Online Plagiarism Checker For Students

Writing an academic paper can be challenging when you’re not sure if it’s original enough to pass a plagiarism check. Of course, students take information from various sites before writing their own text. Sometimes, it just so happens that certain parts are very similar to your resources, making your professor think that you’ve just copied work from somewhere. That’s why it’s crucial for any modern college or university student to ensure that their work has 100% original content to maintain academic integrity.

Luckily, a free plagiarism checker online can solve this issue quickly and easily. Many cheap essay writing services use a plagiarism checker for research paper. However, students sometimes forget that they should too. But with so many options that pop up when you ask Google to “check my paper for plagiarism”, how do you choose the right one for detection? We’ve got the solution in the form of PapersOwl’s free plagiarism checker tool! Our simple tool makes it convenient to check any writing task without having to spend a dime. It works quickly and highly accurately, ensuring that you get the top grade you deserve. So, if you want to check plagiarism online before turning your task in, head over to our website and get started!

Accurate Check for Plagiarism with Percentage

Many students wishing to produce original content aren’t quite sure how to get an exact percentage of plagiarised text in their work. This percentage is important since many universities have a certain limit of non-unique words you can have in your essay for it to be considered okay. If your plagiarism search doesn’t give you the exact percentage, you can’t be sure if your assignment will go through or not.

When using a free plagiarism tool, it’s essential to have this data provided to you. Only when you have it can you decide which parts to change and which ones to chuck out to achieve your desired results. Plagiarized content is a big issue in modern educational institutions, so getting reliable and trustworthy results is vital. This is the most essential requirement when you check plagiarism.

PapersOwl’s plagiarism detection tool gives you all the information you need to fix plagiarized content. Whether you’ve fallen victim to accidental plagiarism or have tried to make your life easier by copying some text from different sources, you’ll get an accurate percentage with our plagiarism checker online. If you’re wondering how to check paper for plagiarism, it’s nothing complicated at all! Simply visit our site, paste your whole essay into the relevant text box or upload the text file, click on Check For Plagiarism, and you’ll get accurate plagiarism results in a matter of seconds. You’ll see the problematic parts with plagiarism detected highlighted, with links to where similar content exists. Our service with plagiarism detector will also give you the option to check my essay for plagiarism and then to hire a professional paper writer to fix your task quickly if you're busy with other things!

The Fastest Plagiarism Checker Online

Gaining insight into duplicate content only works if you get your results quickly. There are so many free plagiarism software online that promise to do the job for you. However, a lot of them are clunky, slow, and inaccurate. How can you produce original work without similarity detection you can trust?

PapersOwl stands out in this regard because it will detect plagiarism in seconds. This is a plagiarism scanner that’s able to perform a Swift Check to give you a uniqueness check right there and then. It also conducts a Deep Search, going through millions of sources on the internet to check for plagiarism. A document of about 1500 words takes only about 10 seconds to get processed! You get a clear plagiarism score of how much text is plagiarized and how much is original. All the sources that your essay matches are listed based on how much similarity there is in your academic writing. And on top of that, you get a handy Make It Unique button that’ll take you to an order page where you can ask our expert writers to rewrite your work and make it 100% unique.

All of this is done almost instantly, allowing students to continue do assignments without missing a beat. Not every plagiarism detection software works this quickly, making ours the best one you’ll ever use.

Plagiarism Checker Helps Boost Your Grade

A lot of students make the mistake of considering their papers automatically free from plagiarism. After all, they’ve written it themselves, so how could it be problematic? What they don’t realize is that it’s very easy to borrow some information mistakenly. Turning such a paper in can cause multiple problems, as your professor might think you haven’t done the work at all.

That is why you should always use a plagiarism scanner to test for plagiarized content in your college papers. Our online plagiarism checker for students is designed for this exact purpose. A simple, free plagiarism check could help you check plagiarism, fix any mistakes you see, and submit high-quality text that no one will question.

Our plagiarism detector has a lot going for it. It makes plagiarism detection easier than ever before. Unlike copying and pasting each passage individually into Google, simply upload the whole file into our plagiarism checker free for students, and you don’t have to do anything else. All the matches are highlighted so you know what to change.

The plagiarism test will give you a uniqueness percentage too. This will help you figure out where you stand and how much time you need to adjust anything if required. So, using our copyright checker online free to check your writing is essential. This way, you’ll submit the task only when you’re sure it meets the level of uniqueness required by your school. As a result, your grades will drastically improve when you check for plagiarism.

💯 12 Online Plagiarism Checkers

🔗 references, 🤔 why use a plagiarism checker.

The issues of plagiarism and academic dishonesty become more and more relevant each year. According to some research , 92% of surveyed students stated that they had or knew someone who had cheated .

So, why does this happen?

The researchers have shed light on this phenomenon, and here are some of their statistics:

• 92% of those who plagiarized stated that they did so because they wanted better grades.
• 83% said that they cheated because of procrastination.
• 75% of respondents pointed out that they did not have enough time to finish their assignments.
• 33% have attempted to cheat due to their overloaded class schedule.
• 58% of the surveyed have plagiarized because they lacked an understanding of the subject.
• 50% had little or no interest in the subject.
• 25% of participants believe that anyone can cheat without any consequences.
• 17% of the interviewees cheated because of peer pressure.
• Another 17% think that it does not matter to the professor if their paper is plagiarized.

After taking all of these numbers into account, it is evident that a significant percentage of students commit acts of plagiarism for several main reasons. Among them are poor time management, concern for academic performance, and peer pressure.

Now that you know the causes of plagiarism, it will be beneficial to examine its different types. Generally, these can be divided into two groups: unintentional and intentional.

Intentional Plagiarism

When it comes to intentional plagiarism, it doesn’t necessarily mean that your paper copies the full document written by someone else. This is only one example of cheating out of many others.

Unintentional Plagiarism

Meanwhile, unintentional plagiarism may refer to:

• Forgetting to cite a source when describing something that is not common knowledge.
• Not citing information that you have paraphrased or summarized.
• Failing to use a proper citation style when documenting sources.
• Misquoting an author, even if it is appropriately cited in the paper.

When composing your paper, it is important to stay vigilant. This is why it is handy to utilize the help of our plagiarism checker (2000 words). Free detection software is a quick and easy way to confirm your paper’s originality.

🔍 How to Check for Plagiarism

As you work on your paper, you may start to ask yourself: How can I avoid plagiarism altogether?

Below, we have prepared some tips that will help you write a 100% original essay:

• Regulate your time. As mentioned earlier, procrastination and a full class schedule may lead to plagiarism. To stay on top of everything, don’t put off urgent tasks until tomorrow. Read up on time management techniques and figure out an efficient study method that works for you.
• Cite while you write. Get in the habit of citing sources in full as you write your paper. Firstly, doing this will save you plenty of time for putting together a bibliography. Second, it will significantly decrease the risk of an improper citation.
• Use only trusted sources. There are a lot of websites with questionable content. Even documents that seem scholarly at first could turn out to be another student’s paper. Ascertain that you understand the source and the ideas that it is trying to convey.
• Understand the difference between various citation styles. An improper citation may result in a penalty for plagiarism. So, make sure you rely on a high-quality reference guide and implement the correct style. Don’t forget to add quotation marks when using unchanged phrasing from the source.
• Use plagiarism scanners before you submit your paper. Even if you wrote your piece from scratch, we still advise you to double-check it. From time to time, you might unintentionally “borrow” a couple of phrases that appear in other works. Despite it being an accident, your professor might penalize your paper. To avoid this, you can use one of the online free plagiarism detectors.

Perhaps our free plagiarism checker (2000 words & more) wasn’t exactly what you were looking for. If you find yourself in need of a tool with slightly different features, this section is for you!

Below, we have prepared a list of 12 online plagiarism scanners , both chargeable and free. They will allow you to avoid similarities with other works on the Internet.

Scribbr is a plagiarism checker powered by Turnitin, a plagiarism-detection system used by most universities. Therefore, it is an excellent choice for those seeking access to Turnitin but not being able to get it. Scribbr offers a free version, but it only allows you to see whether your paper contains potential plagiarism. To see a full report, you have to go premium, which starts from $19.95 per document.

2. Grammarly

Grammarly is famous for its superior grammar-checking software. However, with a paid version, you’ll also get access to its plagiarism detector. It can check your paper against billions of web pages, but its detection doesn’t cover gated and academic content. It also fails to identify rephrased content.

3. PlagScan

PlagScan is an outstanding plagiarism detection tool that is useful for students and writers alike. The website compares your paper against web sources, journals, and internal repositories. It doesn’t offer a free plan, but it allows you to check your first 2,000 words without charge during your free trial.

4. PaperRater

PaperRater is another plagiarism detection service. It operates as freemium software and provides you with a free report. The chargeable version allows you to get a printed summary of your results that contains more detailed information. This program is also integrated with a proofreader and supports various file types for upload.

5. Plagiarisma

Plagiarisma is a simple and free tool for students to use. It works with Google, Yahoo, Bing, and Scholar databases. Don’t forget to register to check your paper!

6. Dupli Checker

At first glance, Dupli Checker is similar to those mentioned above. However, this website has extra features, such as a text spinner, spell checker, word counter, etc. Of course, it also detects plagiarism and provides you with stats, links to plagiarized URLs, and highlights of related phrases. Did we mention that it’s free?

Viper , also known as ScanMyEssay, is a plagiarism detector supporting 56 languages. It checks your content against over 10 billion sources and can scan multiple files at once. Viper offers a free trial, allowing you to check one document of up to 5,000 words. It’s a good option for students who need to scan their papers for plagiarism occasionally.

8. PlagAware

PlagAware offers high-quality plagiarism detection and checks your papers against over 70 billion sources! It has a free plan that allows you to scan 10 pages per month. Moreover, if you choose a premium plan, you pay only for the first check of every document, while subsequent scans of the revised versions are free.

9. Copyscape

Copyscape is a plagiarism detector that can check your paper against online sources and web pages. It doesn’t check your content against academic databases, books, scholarly journals, and offline sources. So, it’s suitable for online content creators and website owners, while students seeking to check academic writing should opt for something else.

10. Copyleaks

Copyleaks offers both free and paid accounts to its users. In both cases, you have to register to use this service. If you have a free account, you can upload up to 2,500 words per month and use two checks. You will also see the history of your previous plagiarism scans.

11. Quetext

Quetext is a user-friendly plagiarism checker that allows you to edit text directly within the tool and has a useful feature — a citation assistant. However, you can check only 500 words with their free plan. After exhausting this limit, you have to go premium. It can also fail to identify plagiarism from scholarly sources like student dissertations or journal articles.

12. SmallSEOTools

The last paper plagiarism checker tool in our list, SmallSEOTools , allows you to check up to 1000 words per search for free. The amazing thing about this tool is that it’s available in English, Chinese, Russian, Italian, French, Portuguese, Spanish, German, and Japanese languages.

Remember – for students, getting caught plagiarizing may mean a failing grade, suspension, or even expulsion. For professionals, the stakes are even higher. Therefore, make sure to use our plagiarism checker for 100% accurate results!

Best Plagiarism Checkers Compared

Published on May 20, 2024 by Koen Driessen . Revised on July 11, 2024.

The best plagiarism checker should be able to detect plagiarism the most accurately, even if the original phrasing has been altered. The tool should also provide a clear, comprehensive plagiarism report.

To identify which plagiarism checker is best, we conducted in-depth research comparing the performance of 10 checkers. We uploaded plagiarized texts that were either directly copied and pasted or edited to varying degrees. In total, we used 140 sources to construct our test documents.

Overview of total scores per plagiarism checker, based on the amount of detected plagiarism:

Table of contents

Our process for comparing checkers, 1. scribbr review , 2. plagaware review, 3. quetext review, 4. viper review, 5. grammarly review, 6. plagiarism detector review, 7. copyleaks review, 8. smodin review, 9. compilatio review, 10. writer review, frequently asked questions about plagiarism checkers.

In order to find the best plagiarism checker, we analyzed different aspects of the tools, focusing on both depth and breadth.

We based our analysis on the following factors:

• Access to the biggest and most varied database
• Ability to detect the most plagiarism for the most source types
• Ability to detect plagiarism when the plagiarized texts have been paraphrased
• Highest quality of matches
• Level of user-friendliness and trustworthiness

We used the same test documents, test date, evaluation criteria, and data analysis for each tool in order to objectively compare the plagiarism results side by side. This ensured that the results required very little interpretation on our part.

“Catches plagiarism more accurately than any other checker”

• Finds the most plagiarism and works for edited texts, too
• Does not store or sell documents
• Offers a happiness guarantee and live support
• Offers a Self-Plagiarism Checker to check for self-plagiarism
• Offers a limited free version
• Quality comes at a price
• Cannot work directly in the tool

Quality of matches

Scribbr performed well for all source types relevant to students, such as journal articles and dissertations.

Most importantly, Scribbr’s checker was the most successful at detecting plagiarism in source texts that had been heavily edited to mimic accidental paraphrasing plagiarism.

Scribbr was also able to find full matches. This means the entire plagiarized portion is matched correctly to just one source, rather than multiple incorrect sources.

The results are presented in a clear, downloadable overview. Different colors are used for different sources, making it easy for users to assess each plagiarism issue separately.

Issues can be fixed with Scribbr’s free citation generator , which generates proper citations for any missed or improperly cited sources.

Users can also choose to combine the Plagiarism Checker with the Self-Plagiarism Checker , which is unique to Scribbr. This tool allows users to upload their own unpublished documents in addition to the public database.

Instead of requiring users to subscribe to their services, Scribbr charges per plagiarism check ($19.95–$39.95, depending on the word count).

However, users are unable to work directly in the tool, and it is not possible to re-check your document for free.

Trustworthiness

Scribbr does not store the uploaded documents, sell them to third parties, or share them with academic institutions. Data is automatically deleted after 30 days, or students can opt to manually delete their document after the check.

Scribbr has live and responsive customer support to assist students in multiple languages. There is easy access to a plagiarism checker guide and other free resources about plagiarism.

Scribbr also has a happiness guarantee, where students receive a new check or refund if they aren’t satisfied for any reason.

Try Scribbr’s Plagiarism Checker now

• Detects most of the plagiarism
• Documents not stored in database
• Multiple support options, but no live support
• Difficult to read PDF reports
• Does not work well for scholarly sources

Plagaware was often able to find full matches and attribute the text to the correct source. However, it performed poorly with heavily edited texts.

Sometimes, the tool did not correctly distinguish between separate plagiarized sources (i.e., it incorrectly attributed two consecutive paragraphs to the same source).

The website report is easy to navigate as it uses different colors for sources. The tool has a function that tells you how many words a plagiarized section has and gives a similarity percentage.

Unfortunately, the downloadable report is confusing to read as it uses only one color and doesn’t clearly link plagiarized text with a source.

Plagaware does not store files and does not sell uploaded content. Their website contains a contact form and phone number.

Discover Plagaware’s plagiarism checker

• Users can work directly in the tool
• Offers a citation assistant that helps with adding missing citations
• Partial matches where one source text is matched to multiple sources
• Reports are hard to read

Quetext detected about half the plagiarized text but was often unable to fully match the entire source text to one source. Instead, individual sentences get attributed to different sources.

The website states that Quetext checks against webpages and academic sources, but the tool does not in fact perform well for academic sources.

The website report sometimes did not correctly distinguish between plagiarized paragraphs and attributed them to the same source.

Quetext differentiates by severity of plagiarism in its online report: orange for partial matches and red for full matches. Otherwise, the same colors are used for different sources.

Users can work directly in the tool, and Quetext offers a citation assistant that helps generate the missing citations.

The original layout of the text is lost in both the website report and the downloadable report.

The tool does not store or re-upload your text, and it offers a help center with FAQs. There is no live support, but users can submit a help request on the website.

Discover Quetext’s plagiarism checker

• Ability to compare your newest document with previously uploaded documents
• Different colors for different source types
• Documents get published on external websites if you use the free version
• Performs poorly for scholarly sources
• Report can be hard to read, due to partial matches

Viper found about half of the plagiarism when the source text was directly copied or lightly edited, but it struggled to find plagiarism in moderately and heavily edited texts.

The tool had average performance for most source types but struggled specifically with scholarly source types such as journal articles and dissertations. This makes this tool less useful for students.

When Viper flagged plagiarism, it often matched the entire passage to one source. While the downloadable report was somewhat difficult to read, it helpfully uses different colors for different sources.

Viper also allows users to check their text against their own previously uploaded documents, which may help to catch instances of self-plagiarism.

Viper stores previous submissions and shows matches with those texts.

The tool does not sell your document if you use the paid version (prices start at $3.95 per 5,000 words). However, if you use the free version, the document is uploaded to an internal database. After three months, the text is published on an external website as an example for other students. This is not good if the content of your text is confidential.

Viper does not have live support, but there is a contact form on the website.

Discover Viper’s plagiarism checker

• Offers a language and citation assistant
• Does not sell or share documents with other parties
• Finds quite a low percentage of plagiarism
• 100,000 character limit (14,000–25,000 words)
• Same colors for different sources

Grammarly found a relatively low amount of plagiarism. It performed best with lightly edited texts. However, it scored below 50% in all other rounds of testing.

When it did find plagiarism, the tool was often able to find the right source. However, the matches were usually only partial and rarely included the entire plagiarized section.

The design is not very clear. As the tool is primarily used as a language checker, the plagiarism checker function is somewhat difficult to find. The tool uses the same color for all sources, making it hard to read.

The subscription comes with a language and style tool and offers a citation assistant that helps generate the missing citations. In addition, there is a 100,000 character limit for both the monthly plan ($30 per month) and the yearly plan ($12 per month).

For more information, you can read our in-depth  Grammarly review .

Grammarly does not store, sell, or share documents with other parties.

There is a support page with tips, tutorials, and FAQs, and it is possible to submit a question via a form. However, there is no live support.

Discover Grammarly’s plagiarism checker

• Does not store or sell your document
• Difficult to find the plagiarized source in the report
• Same highlight colors for different sources
• Technical difficulties generating the report, and no live support

This tool had difficulty uploading the document for each round of testing (for the first round, it took over six hours to generate a report). It seems that Plagiarism Detector was unable to adequately process a document of this size, even though the document did not exceed their word limit of 25,000.

This tool was mostly only able to find partial matches, attributing individual sentences to one or more sources, rather than the entire section.

In the downloadable report, the format of the text is lost, making it hard to read. The list of sources is also difficult to cross-reference with the text above because the same colors are used for different sources.

Plagiarism Detector offers a rewrite tool to help resolve similarities, but the quality of this tool is questionable, and it does not help with the citation issues. You should resolve plagiarism by citing the relevant source, not by attempting to rewrite the text to disguise it.

Plagiarism Detector does not store or sell uploaded documents. There is no live support, but the website does offer a help request form.

Discover Plagiarism Detector’s plagiarism checker

• Text layout is kept intact in the online tool
• Difficult to read reports
• Performed poorly with academic sources
• Unclear data protection policy

Copyleaks performed relatively poorly with all source types. It lists multiple possible sources for flagged sentences. However, it was sometimes able to attribute an entire source block to the correct source.

The report distinguishes between text that is “identical” to a source, text that contains “minor changes,” and text that is “paraphrased.” However, its judgment is sometimes wrong.

The site report and downloadable report differed (the downloaded report flagged content that was not flagged on the site report). On the website report, the source information function did not always work correctly, so it was sometimes impossible to check the accuracy of the attributions.

The reports were also difficult to read, as they use the same color highlights for all sources. While the source formatting is maintained in the online tool, it is altered in the downloadable report.

Copyleaks claim that they “will never steal your work.” To permanently remove uploaded content from their database, users must contact customer support. The website has a chat option and a contact form.

• Site has a citation generator
• Very low word limit
• Report is difficult to read
• Scans individual sentences rather than full texts

Smodin performed relatively poorly in all rounds of testing. While it got some sources correct, it struggled to get full matches and frequently attributed the same text to multiple different sources. It did particularly poorly with scholarly sources.

The tool has a very low limit of 2,000 words per scan.

Both the online report and the downloadable PDF report are difficult to read. The downloadable report displays the uploaded document, but it doesn’t highlight the text that it flags as plagiarized. Instead, below this, it includes the individual parts of the text that it recognizes as plagiarism.

However, it is difficult to read as the same text is repeated over and over again if multiple sources were found for it. The sources also do not seem to be in a logical order.

Their data protection policy suggests they can/might sell or repurpose uploaded content. There is no live support, but there is a contact form on the site.

Discover Smodin’s plagiarism checker

• You can use your credits for multiple documents
• Scans against other documents you have uploaded
• Doesn’t highlight the plagiarized parts in the text
• Hard to review and resolve instances of plagiarism

Compilatio was able to find a few of the plagiarized sources, but it struggled if the source text had been moderately or heavily edited. However, when it was able to identify a source, it was often correct.

It was not possible to determine how accurately Compilatio could match the source to a plagiarized source text, since the plagiarized parts were not highlighted. Instead, the report only shows the general area that matches the source. This may limit its helpfulness to users, since it’s hard to review and resolve potential instances of plagiarism.

As the report does not highlight the flagged text, it does not provide a good overview of the potential issues. Additionally, you cannot work in the tool, so it’s not possible to exclude similarities from the report.

The tool scans the text against other documents you have uploaded, which can help to avoid self-plagiarism.

Users can buy packages for 5,000 words for €3.99 (no $ value is available on the site), 25,000 words for €14.99, or 50,000 words for €24.99. These credits can be used for multiple documents and are valid for 12 months after purchase.

Compilatio does not share or sell submitted documents, and the documents are not used as comparison material for other users.

There is no live support available, but they do provide a helpdesk with FAQs and a request form.

Quality of matches 

This tool found very little plagiarism. It struggled particularly with scholarly sources like dissertations and academic journals.

It scans sentence by sentence, rather than whole paragraphs. As a result, the plagiarized text is often attributed to multiple sources, rather than just one.

The plagiarism checker function is part of a larger language tool that provides grammar and spelling checks. As the tool doesn’t display an overall plagiarism percentage, we couldn’t apply our normal testing methodology. 

The tool has a nice, clean design and was relatively easy to use. The format of the text remains intact, and you can work directly in the tool. However, it doesn’t provide a downloadable report, so you must work solely on the website.

Writer claims that its tool is secure and safe to use and that it won’t share your information with anybody. A detailed security policy is described on a separate page.

Plagiarism can be detected by your professor or readers if the tone, formatting, or style of your text is different in different parts of your paper, or if they’re familiar with the plagiarized source.

Many universities also use plagiarism detection software like Turnitin’s, which compares your text to a large database of other sources, flagging any similarities that come up.

• Unorganized papers often lead to plagiarism. You should be very careful while copying word-by-word. You can use "Quotes" to highlight the part which is copied with a source.
• Never trust Free services. Writing about the thousandth time, Do not use free tools. They will only lead you to false results and the risk of getting plagiarized with your own work. Paying someone to check your work on Turnitin will only lend you to hazard.
• If Your paper is an assignment, always do everything as instructed by the professor.

Today, copyrighted content has become a constant problem in educational institutions. Students create many assignments using a lot of research in a short period. Many schools/institutions, such as Duke University, have judicial affairs offices. They will review each case of plagiarism and fix penalties.

Most of the outcomes of plagiarism occur once the replication is caught. Institutions have noted that students who duplicate data often fail to learn research and writing skills. Once they leave the institution, all those students lose the ability to create original content because they have only cheated before.

Professional

Countless journalists, academics, writers, and creators have had their reputations damaged by plagiarism accusations. Not only do plagiarists disrupt their ongoing work by getting fired or terminated. They also find it difficult to get work in the future. A particularly egregious instance of plagiarism, or worse, can destroy a person's professional image. It also forces them to change careers to avoid the stigma of plagiarism.

Apart from all the professional and personal difficulties that may arise in certain cases, there are also legal consequences. Copying copyrighted material for profit may result in the plagiarist having to pay some financial losses. In some cases, copying data can subject the plagiarist to criminal prosecution.

Similar to all other forms of theft, plagiarism also has many disadvantages associated with it.

It can take place in both intentional, when you try to pass someone’s content as your own, or unintentional when you forget to mention the source for your work correctly. In spite of the kind, piracy always has consequences when it is discovered. Mostly, the punishment of accidental copying is temporary.

Check for unintentional plagiarism

Easily check your paper for missing citations and accidental plagiarism with the EasyBib plagiarism checker. The EasyBib plagiarism checker:

• Scans your paper against billions of sources.
• Identifies text that may be flagged for plagiarism.
• Provides you with a plagiarism score.

You can submit your paper at any hour of the day and quickly receive a plagiarism report.

What is the EasyBib plagiarism checker? 

Most basic plagiarism checkers review your work and calculate a percentage, meaning how much of your writing is indicative of original work. But, the EasyBib plagiarism checker goes way beyond a simple percentage. Any text that could be categorized as potential plagiarism is highlighted, allowing you time to review each warning and determine how to adjust it or how to cite it correctly.

You’ll even see the sources against which your writing is compared and the actual word for word breakdown. If you determine that a warning is unnecessary, you can waive the plagiarism check suggestion.

Plagiarism is unethical because it doesn’t credit those who created the original work; it violates intellectual property and serves to benefit the perpetrator. It is a severe enough academic offense, that many faculty members use their own plagiarism checking tool for their students’ work. With the EasyBib Plagiarism checker, you can stay one step ahead of your professors and catch citation mistakes and accidental plagiarism before you submit your work for grading.

Why use a plagiarism checker? 

Imagine – it’s finals week and the final research paper of the semester is due in two days. You, being quite familiar with this high-stakes situation, hit the books, and pull together a ten-page, last-minute masterpiece using articles and materials from dozens of different sources.

However, in those late, coffee-fueled hours, are you fully confident that you correctly cited all the different sources you used? Are you sure you didn’t accidentally forget any? Are you confident that your teacher’s plagiarism tool will give your paper a 0% plagiarism score?

That’s where the EasyBib plagiarism checker comes in to save the day. One quick check can help you address all the above questions and put your mind at ease.

What exactly is plagiarism? 

Plagiarism has a number of possible definitions; it involves more than just copying someone else’s work. Improper citing, patchworking, and paraphrasing could all lead to plagiarism in one of your college assignments. Below are some common examples of accidental plagiarism that commonly occur.

Quoting or paraphrasing without citations

Not including in-text citations is another common type of accidental plagiarism. Quoting is taking verbatim text from a source. Paraphrasing is when you’re using another source to take the same idea but put it in your own words. In both cases, it’s important to always cite where those ideas are coming from. The EasyBib plagiarism checker can help alert you to when you need to accurately cite the sources you used.

Patchwork plagiarism

When writing a paper, you’re often sifting through multiple sources and tabs from different search engines. It’s easy to accidentally string together pieces of sentences and phrases into your own paragraphs. You may change a few words here and there, but it’s similar to the original text. Even though it’s accidental, it is still considered plagiarism. It’s important to clearly state when you’re using someone else’s words and work.

Improper citations

Depending on the class, professor, subject, or teacher, there are multiple correct citation styles and preferences. Some examples of common style guides that are followed for citations include MLA, APA, and Chicago style. When citing resources, it’s important to cite them accurately. Incorrect citations could make it impossible for a reader to track down a source and it’s considered plagiarism. There are EasyBib citation tools to help you do this.

Don’t fall victim to plagiarism pitfalls. Most of the time, you don’t even mean to commit plagiarism; rather, you’ve read so many sources from different search engines that it gets difficult to determine an original thought or well-stated fact versus someone else’s work. Or worse, you assume a statement is common knowledge, when in fact, it should be attributed to another author.

When in doubt, cite your source!

Time for a quick plagiarism quiz! 

Which of the following requires a citation?

• A chart or graph from another source
• A paraphrase of an original source
• Several sources’ ideas summarized into your own paragraph
• A direct quote
• All of the above

If you guessed option E than you’d be correct. Correct punctuation and citation of another individual’s ideas, quotes, and graphics are a pillar of good academic writing.

What if you copy your own previous writing?

Resubmitting your own original work for another class’s assignment is a form of self-plagiarism, so don’t cut corners in your writing. Draft an original piece for each class or ask your professor if you can incorporate your previous research.

What features are available with the EasyBib plagiarism checker? 

Along with providing warnings and sources for possible plagiarism, the EasyBib  plagiarism checker works alongside the other EasyBib tools, including a grammar checker  and a spell checker . You’ll receive personalized feedback on your thesis and writing structure too!

The  plagiarism checker compares your writing sample with billions of available sources online so that it detects plagiarism at every level. You’ll be notified of which phrases are too similar to current research and literature, prompting a possible rewrite or additional citation. You’ll also get feedback on your paper’s inconsistencies, such as changes in text, formatting, or style. These small details could suggest possible plagiarism within your assignment.

And speaking of citations, there are also  EasyBib citation tools  available. They help you quickly build your bibliography and avoid accidental plagiarism. Make sure you know which citation format your professor prefers!

Great! How do I start? 

Simply copy and paste or upload your essay into the checker at the top of this page. You’ll receive the first five grammar suggestions for free! To try the plagiarism checker for free, start your EasyBib Plus three-day free trial.* If you love the product and decide to opt for premium services, you’ll have access to unlimited writing suggestions and personalized feedback.

Scribbr partners with Turnitin, which can detect everything from precise word and phrase matches to language where synonyms have been to used, and Scribbr checks writing against a database that covers 91 billion web pages and 69 million publications. Impressively, you can upload old assignments or referenced works to compare, too – perfect if you want to check your writing against something that won’t be in Scribbr’s database.

Beyond plagiarism, Scribbr offers expert editors who can edit essays, thesis documents, funding proposals, and literary reviews – it’s ideal for making sure that your academic work is top-notch, no matter the subject. Scribbr also provides a generator and checker for APA citations so you can be sure that no-one will question your sources.

Scibbr’s plagiarism checking service ranges in price from around $20 / £14 / AU$27  to $40 / £32 / AU$63, depending on the length of the document, and you’ll get your checked document within ten minutes.

The lack of dashboard and security features, when compared to other services, means that Scribbr isn’t suitable for large enterprises. But if you’re a student or academic, it’s well-designed and potentially invaluable.

3. Grammarly

Grammarly is one of the world’s most popular writing assistants, and no wonder: it does a fantastic job of checking written work for linguistic accuracy alongside its readability and tone. It’s also available as an app, as a plug-in for most word processing tools and as a browser extension.

It works in email clients , on social networks, and even in Slack and Discord too – so you’ll always be able to rely on this tool.

Grammarly has a great plagiarism checker, too. It uses the academic papers in ProQuest’s database and more than 16 billion web page sources to check for plagiarized text, and if the app detects copied language or phrases then you’ll get an alert in your document.

Grammarly’s plagiarism checker is free to use, but we don’t recommend this option – it will tell you if you’ve plagiarized, but it won’t show you where.

Instead, we recommend signing up to Grammarly’s paid tiers – you get its grammar, spelling, and punctuation tools alongside its clarity, engagement, tone, and plagiarism detection. Grammarly is one of the best linguistic tools on the web.

Grammarly’s prices start at around $11 / £10 / AU$16 per month.

4. PlagScan

PlagScan is a robust plagiarism deterrent focused on the academic circle. While used by many other fields as well, the features that make PlagScan stand apart among other plagiarism tools seem geared in this direction.

Pricing is pretty reasonable, with plans per word for individuals and some business plans as well. Prices can vary from $6 - $50 or more on average. On the higher level plans, there are advanced features including API abilities, support and more. There is also the ability to create more detailed reporting and integrate with tools you are already using.

Compared to other tools, PlagScan is pretty good about picking up possibilities, albeit sometimes too good. There are the occasional mistake, as in it notifies of a plagiarized item that is not actually there, however all around this tool is fairly accurate.

PlagScan itself even will say that the only true way to see if something is plagiarized is to utilize human support, confirming what PlagScan finds. But, without this tool, you would take much longer to find these similarities!

Lastly, there are easy color-coding highlights that help show what kind of infraction is found in offending pieces of writing.

5. Plagramme

Plagramme has a range of features that goes beyond what you’ll find with many other anti-plagiarism tools. It doesn’t just check billions of sources – it highlights your article with plagiarism risks, potentially paraphrased sections, poor citations, and textual similarities. Combine this with a straightforward scoring system, and you’ll be able to quickly see how much of any article is at risk.

This system is multilingual, so it can detect issues in different languages, and Plagramme also offers an authenticity service where its own editors check and fix documents manually. This does cost more, but it’s ideal if you have an important document that needs perfection. And, at the other end of the scale, there’s a free plagiarism checker – although this performs a quick check without the in-depth reporting or database access of the full product.

Once you’ve signed up for an account then you’ll be able to see Plagramme’s full range of services. It’ll cost a few dollars to skip the queue and a few more to get an in-depth report, and you can buy credits that work on any of Plagramme’s services.

This credit-based system and the emphasis on individual documents mean that Plagramme may not suit large organizations, but it’s well-suited to individuals and small businesses. 

Quetext has plagiarism detection algorithms that use a system called DeepSearch, which relies on word placement, deep learning, and contextual analysis to deliver smarter and more sensible results when you scan a document.

This tool can check for plagiarism in academic documents, news articles, blog posts, and webpages, so it’s versatile. It’s easy to use too: potentially plagiarized words or phrases are highlighted using a color-coded system with bolder shades for more significant issues. Side-by-side displays mean you can see exactly where the plagiarized text originated. And, at the end of the process, content gets a score so you can see how it’s performed.

Quetext also prizes itself on its straightforward pricing. If you pay for the basic package that allows you to check 100,000 words. The Plus package doubles the cost and increases the word allowance to 250,000, and there’s an Organization option that’s ideal for companies. Impressively, every product includes every feature – the good stuff is never held back for those who are willing to pay more.

Plagiarism checker FAQs

What is plagiarism.

Simply put, plagiarism is cheating. it refers to the act of copying one’s content and passing it off as your own. Grabbing someone’s photo and using it without permission and/or proper credits can be considered an act of plagiarism. Taking some text from a source and using it on your website without proper citation is also an act of plagiarism. 

In college, getting caught plagiarizing can lead to expulsion and can ultimately end any plans you have for your future. Stealing content for your own blog is not considered a form of flattery either, nor is it legal. Copying content for your own website can get you reported and your website taken down. 

What are the common types of plagiarism?

There are a couple of ways to commit plagiarism, but here are the five most common types:

1. Verbatim plagiarism - This is a common crime wherein a text or content is copied exactly as it is written without any form of credit or citation. 

2. Mosaic plagiarism - This type of plagiarism involves copying content from different websites or sources and combining them without any form of credit or citation. 

3. Global plagiarism - This means deliberately claiming someone else’s entire work as your own. 

4. Self plagiarism - This is when you resubmit your own work when you’ve already used it. It’s also known as auto plagiarism.

5. Accidental plagiarism - This occurs when you unintentionally commit plagiarism by paraphrasing a content and failing to cite or add credits. 

As content is a vital ingredient in SEO ranking which is always a neck to neck competition, websites are usually trying to come up with more content than they likely would have expected to be needing. A team of writers usually solve the problem, but it’s also where a new problem arises - monitoring the content.

Whether it’s an intentional copying of content or a missed citation, quote or credit, plagiarism isn’t as easy to detect if you’re dealing with tons of articles to check. The good news is that there are resources available - plagiarism checkers - that you can utilize to make it an easier task.

How to choose the best plagiarism checkers for you?

When choosing the best plagiarism checker for yourself, you'll want to start with assessing whether you want a standalone plagiarism checker or something with more features to improve writing. 

You'll want to consider the tool's user interface and learning curve. The simpler it is to operate, the more efficient you can be with your checking. 

If you're working alone, you may do well with a certain type of plagiarism checker, but the same tool may not be suitable for larger organizations. 

You'll also want to take the plagiarism tool's pricing into consideration, check how many users it can support, and analyze how well it integrates with third-party apps. 

How we test the best plagiarism checkers

To test the best plagiarism checkers, we first evaluated whether the tools are standalone plagiarism checkers or if they offer a suite of language improvement tools. 

We analyzed how large their content database is, whether there's citation checking, and what third-party apps they integrate with.

We assessed the tools' user interface and learning curve, and the kind of algorithm they were using to effectively spot plagiarism. We also considered their pricing plans, the number of users supported on each plan, and what type of client they'd be ideal for, among other things.

How you can avoid plagiarizing

Know the different types of plagiarism

There are several types of plagiarism, and it’s essential to understand the differences to avoid making these mistakes and prevent plagiarism in the classroom.

• Direct plagiarism: Using someone else’s exact words and using them as your own with no credit to the source. Eliminating portions of the text still qualifies as direct plagiarism.
• Patchwork plagiarism: Creating new text by combining exact phrases or sentences from multiple sources without acknowledging the original authors or sources.
• Self-plagiarism: Attempting to reuse or recycle your previous work and claiming it as a new piece of work without mentioning the source of original publication.
• Source-based plagiarism: Producing false sources within your writing or omitting one or more references from citations.

Cite your sources

Students often think of citations as a simple means of acknowledging another author's work. While this is their main purpose, there are other benefits as well.

Source citations also show readers where to go to learn more. By providing context around the citation in student papers, such as the source medium and when it was published, readers can locate the information more easily. Giving too little source information or improperly formatting it can result in unintentional plagiarism. These mistakes also make it difficult for readers to locate the original source and verify information.

Quetext's citation generator makes it easy for students to accurately cite their sources without slowing down their writing process. Once a user inputs the text, the software identifies the passages that require a citation and subsequently generates it in the style required — APA, MLA, or Chicago.

Always use a plagiarism checker

The best way to avoid severe plagiarism consequences is to use a plagiarism checker. Often, plagiarism is unintentional and results from poor paraphrasing of material found online. Using a plagiarism checker, the student can avoid accusations of any kind of plagiarism and benefit from a close review of the original material.

Quetext's plagiarism checker provides a speedy, easy process for students to receive accurate results, identifying areas of concern and providing on-page solutions.

Plagiarism Checker for Students FAQ

What are the consequences if a student is caught plagiarizing.

The consequences of plagiarism vary according to the student’s academic institution and grade level. For example, a middle school student who plagiarizes within an essay may receive a stern warning and additional instruction related to the process of citing sources or summarizing one’s thoughts.

However, students in higher education institutions guilty of plagiarism in academic papers face much steeper repercussions, including, but not limited, to failing grades and disciplinary or legal action. Factors such as the assignment itself, the instructor, and whether or not it is your first offense impact the outcome.

Depending on the severity of the situation, plagiarism can also impact a student’s reputation or future career opportunities.

How does a plagiarism checker help students?

A plagiarism checker helps students be proactive in finding instances of plagiarism before an assignment is completed and turned in with no way to correct the errors.

In addition, by identifying the potential conflicts early, students can conduct further research to find alternative sources to understand the material better and revise or rewrite the offending passages.

Plagiarism checkers also help students learn innovative writing techniques, improve their writing skills through better research and experience in summarizing ideas, and preserve academic integrity.

Do teachers use plagiarism checkers?

Many teachers use plagiarism checkers to ensure a student’s submission is 100% original work. With the rise of easy-to-use tools like Quetext, checking for authenticity and text matches is a quick and affordable process to scan millions of online data sources.

Using plagiarism checkers also allows teachers to educate their students on the importance of citing sources and the ethical responsibilities of research and opinion writing.

Plagiarism has always been a source of concern for teachers, but until now, options for manual detection have limited their opportunities to identify the problem efficiently. However, the evolution of technology in this area has made the tools more accessible than ever.

How do teachers check a paper for plagiarism?

Teachers are skilled at detecting plagiarism, especially those who have been teaching for a significant period or who teach in the areas of English or Literature. Some teachers use a simple technique of entering a sentence into a search engine to find instances of duplicate text on web pages.

However, this manner of plagiarism detection is manually intensive and dependent upon unreliable algorithms. Some may use their writer’s intuition by identifying anomalies in sentence structure, inconsistencies in vocabulary or grammar, or a combination of all of these.

Others use more sophisticated and robust plagiarism detection software, like Quetext. Quetext can scour millions of sites using DeepSearch™ technology to identify plagiarism in seconds. These tools also enable instructors to work with students to improve their writing and avoid repeating the same mistakes in the future.

Can students get in trouble for accidental plagiarism?

Yes, students can be penalized for plagiarism, even if it was an accident. Unfortunately, instructors have no way of knowing the intent behind plagiarism. Depending on the type of plagiarism, instructors may allow leeway for students to learn from their mistakes and correct the work without the threat of severe consequences.

However, repeat offenders are less likely to receive this flexibility and may face steeper penalties. Additionally, instructors of college-level courses with clear plagiarism guidelines and policies may be less inclined to let students off the hook and instead enforce severe consequences.

Is there a free plagiarism checker for students?

Yes! Quetext offers both a free and a paid subscription for students to seamlessly verify their writing. Quetext goes beyond traditional plagiarism checkers to provide students with advanced technology that puts content through three layers of evaluation in just a matter of seconds. This level of insight enables students to understand the degree to which the text has been plagiarized and decide whether to rewrite the text or use the citation assistant to cite sources.

Quetext also offers a detailed report students can use to document their editing efforts and present as proof of a plagiarism-free, 100% original content document.

Quetext's plagiarism tool also offers flexible pricing for its Pro features which facilitates the citation of online sources, attributions, and real-time feedback for writing improvement.

How can a student check for plagiarism?

Anyone can enter the text from a research paper into a search engine and find potential matches that identify instances of plagiarized content or duplicate content. However, this method is largely ineffective and does not identify every area of concern.

Students can use Quetext's free online plagiarism checker by creating an account, copying and pasting the text in question into the plagiarism checker, and receiving a comprehensive analysis with color-coded feedback, a plagiarism percentage score, and options for editing the text.

Quetext is one of the best plagiarism checkers available with high-quality insights and accurate results.

Plagiarism checkers: How to pick the best plagiarism checker

Identifying potential plagiarism to supporting formative learning

With a wide variety of plagiarism checkers available on the market these days, it’s more important than ever to have a clear idea of your needs and pedagogical goals as you make your choice.

A note on the term “plagiarism checker”:

Because “plagiarism checker” is a term that is accusatory in tone and plagiarism detection is a judgment call that should be undertaken by humans, this isn’t a term Turnitin often uses. Turnitin doesn’t check for plagiarism in student work; we generate a report that provides text similarity and leave the academic judgment of whether work is plagiarized, to the instructor and academic leaders of an institution. That said, we acknowledge that “plagiarism checker” is an oft-used general term for tools that detect similarity.

We agree with researchers who state, “Plagiarism detection is an academic judgment, which is depending [sic] on plenty of factors, and only expert academicians can do this job” ( Meo & Talha, 2019 ). Notable academic integrity researchers Foltynek, Guerrero-Dib, and Weber-Wulff state similarly, emphasizing, “Plagiarism and similarity are very different concepts. What these tools promise is to find overlapping texts in the document examined. Overlapping texts do not always indicate plagiarism, thus the decision about whether plagiarism is present or not should never be taken on the basis of a similarity percentage. The similarity reports of these tools must be inspected by an experienced human being, such as a teacher or an academic” ( Foltýnek , et al., 2020 ).

Informing your choice of similarity checking tools

We acknowledge that choosing a similarity checking tool can be a fraught process for academic leaders. So what are key criteria and questions to consider when finding the best solution for your students, faculty, staff, and overall institution? And how can a solution go beyond simply identifying similarity and potential plagiarism but also serve as a formative learning tool? How can a solution support the lofty goal of transforming plagiarism into a teachable moment?

What matters most in the evaluation of plagiarism checkers and similarity detection tools?

What pedagogical criteria should academic leaders consider in choosing a “plagiarism checker?”

There are many factors to consider when choosing an edtech tool, and in turn, a plagiarism checker or similarity detection software. Pedagogical criteria are of utmost importance. An Edutopia article defines criteria in evaluating edtech tools as:

Student experience

Intrinsic motivation.

• Zone of proximal development
• And teacher experience ( Miller, 2020 )

How effective is the solution in upholding academic integrity and supporting student learning? While this factor is often muddied by marketing writing, it is a top question to ask when it comes to picking a similarity detection tool. The best option is to look at objective academic research and customer testimonials .

It is challenging to determine the efficacy of tools that haven’ t been around very long. Software that has been in existence for years or decades is subject to research and user stories that can provide transparency into how robust or helpful they are in upholding academic integrity. Multiple research projects over the years state that Turnitin Feedback Studio is effective in reducing plagiarism in student writing ( Li, et al., 2021 ; Kostka & Maliborska, 2016 ; Batane, 2010 ; Baker, et. al., 2008 ).

Can the tool meet a variety of student needs? Is it accessible to all students regardless of disability or circumstance ? How easy is it to use? The best similarity detection tools are ones that students are able to use and experience in positive ways so that they then use it consistently.

Research can also provide insights into student experience. According to Steppenbelt & Rowles, “Student perception of the usefulness and effectiveness of the use of the software was also very positive. Generally, due to the use of Turnitin and the accompanying focus this necessarily placed on the associated issues, students developed a sense that avoiding plagiarism is important. From this perspective, Turnitin appeared to be a successful learning tool in academic writing education” ( Steppenbelt & Rowles, 2009 ).

Is the similarity detection tool one that provides opportunities for learning? It is important to choose a tool where students set the goals, where they have access to feedback and information to guide them in the next steps of learning, and that these are primary features in the product.

A similarity detection tool—or “plagiarism checker”—should not discourage students or act as a policing device but rather provide them with a curiosity about learning and an appreciation of academic integrity.

Academic research found that “Turnitin can be used by learners in strategic ways that facilitated a deeper knowledge and capacity for academic writing practices. Students who demonstrated intentionality in their use of Turnitin engaged with the program in a nuanced way, which supported the self-identification of gaps in their academic literacy knowledge and skills. They then used an array of resources to develop their assignment and more broadly their own learning in this area” ( Orlando, 2018 ).

Zone of Proximal Development

Vygotsky’s Zone of Proximal Development (ZPD) refers to an optimal learning space where the student is challenged with tasks that they cannot achieve alone but with guidance can proceed to next steps ( Shabani, et. al., 2010 ). If the similarity detection tool can support students from unconscious incompetence to conscious competence in skill development , it effectively provides scaffolding for learning and supports the Zone of Proximal Development.

An excellent candidate for similarity detection will have ample opportunities for formative feedback so that plagiarism can be turned into teachable moments .

Research determined a decrease in similarity indices with continued student use of Turnitin. Steppenbelt & Rowles state, “Most students are genuinely interested in learning. The mechanistic application of citation and referencing rules, involving trial and error phases using the Turnitin software, may also be a necessary initial learning stage on the path to competent academic writing…Using the software, students received frequent feedback regarding the originality of their written work and whether sources had been properly acknowledged” ( Steppenbelt & Rowles, 2009 ).

Teacher experience

Finally, a similarity detection tool needs to help faculty both in providing accurate and reliable information to determine a case of plagiarism or misconduct as well as opportunities to teach and guide students. Of course, too, it should be easy to use and optimally, free up time for teachers.

Ask other teachers for their experiences with similarity detection tools. Look to academic research and case studies for evidence on teacher experience. According to Lisa Simperingham, Academic Advisor of Digital Learning at Unitec, “At first, our teachers primarily used Turnitin Feedback Studio for similarity checking. However, as they got used to using the platform, more and more teachers started to use the different feedback functions, attaching rubrics and grading online…The feedback from teachers has been positive. They say that it makes grading faster and easier, and they like the flexibility of being able to do their marking from anywhere. Also, being online, it simplifies the process of returning graded assessments to students.”

How to evaluate similarity detection tools or “plagiarism checkers”

Plagiarism detection shouldn’t be the main methodology in upholding academic integrity, but rather a backline defense. Similarity detection tools that guide students towards academic integrity are the most optimal solution. Additionally, effective assessment design and instruction, as well as honor codes are the foundation of preventing academic misconduct like plagiarism.

That said, according to notable academic integrity researchers, there are factors to consider when evaluating similarity detection tools.

At the 2021 International Center for Academic Integrity’s Conference, Dr. Debora Weber-Wulff presented her findings on various plagiarism detection tools. It was followed by a research article authored by various other notable scholars specializing in academic integrity.

In the article, researchers Tomáš Foltýnek, Dita Dlabolová, Alla Anohina-Naumeca, Salim Razı, Július Kravjar, Laima Kamzola, Jean Guerrero-Dib, Özgür Çelik, and Debora Weber-Wulff conducted an evaluation of the coverage and usability of most known similarity detection tools ( Foltýnek, et. al., 2020 ).

Turnitin, Unicheck, Plagscan, and Urkund had the highest overall scores for coverage and usability as illustrated in their graph .

Author’s note: In 2020, Turnitin acquired Unicheck . In 2021, Turnitin acquired Ouriginal , composed of both Plagscan and Urkund.

For coverage evaluation, the research encompassed language coverage, types of plagiarism sources (e.g., open access journals, Wikipedia , and student papers), plagiarism types (e.g., copy and paste, synonym swapping, translation plagiarism), and single-source versus multiple-source documents.

For usability evaluation, the research reviewed workflow process, result presentation , and other usability issues (e.g., integration into an LMS, call support, and no external advertisements).

These criteria may be used to do your own evaluation and research of similarity detection tools, especially if you want to weigh one factor more than another.

Does your similarity detection tool support AI writing detection?

AI writing tools like ChatGPT are disrupting education in both positive and negative ways. While having essential conversations with students about proper AI writing tool use is the foundation to academic integrity, AI writing detection can also be a deterrent to AI writing tool misuse . While similarity detection tools focus on potential plagiarism, it is important to prepare for the future and ensure that your similarity detection tool is keeping pace with emerging trends in academic misconduct.

Does your similarity detection tool integrate with your existing workflow?

The value of a similarity detection tool is eroded if there are technical and/or perceived barriers affecting educators and students. Software that is cumbersome or inconvenient is unlikely to receive buy-in and risks inconsistent use, or worse still, unchecked incidences of plagiarism. Not only should the tool support academic integrity checks that easily integrate with your daily workflow, it should ideally operate in unison with other teaching functions that nurture academic excellence.

Provision of feedback

Plagiarism is often the product of writing deficiencies, and robust feedback loops are key to assisting at-risk students develop their aptitude and confidence for original work and improving learning outcomes. It’s also a way to make students feel seen and less inclined to take shortcut solutions. However, crafting meaningful feedback at scale is often a hurdle for time poor educators.

In a 2021 study demonstrating synergy between pedagogy and technology, John Hattie teamed up with Turnitin researchers to examine feedback that leads to improvement in student essays. Using both high school and university data in the form of 3,204 student essays submitted through Turnitin Feedback Studio, results were gleaned following the initial submission, receipt of feedback, and resubmission of essays to generate final scores. They discovered that ‘where to next?’ feedback was most powerful, and that “the use of a computer-aided system of feedback augmented with teacher-provided feedback does lead to enhanced performance over time”.

One of many features designed to support feedback delivery within Feedback Studio is QuickMarks , which enables educators to save time on grading and offer richer, more personalized feedback with a library of drag-and-drop comments. Furthermore, the Draft Coach feature guides students through the writing process by blending similarity checking and citation checking with intuitive, real-time feedback so that students develop positive habits in upholding integrity where and as they write.

Grading delivery

With an all-in-one solution to surface plagiarism or validate the originality of student work as part of the overall grading process, educators can gain efficiency plus additional insights into what students know, what they struggled with, and next steps for both the instructor and student.

Ensuring that grading is based on clearly communicated learning objectives and standards is a key component to student success and mitigating the risk of misconduct such as plagiarism or student collusion. Rubrics are, in essence, not only part of assessment but also a teaching and learning junction with the potential to increase student learning outcomes and uphold integrity. By providing rubrics prior to assessment and mapping feedback to the rubric, students better understand how they are measured.

Turnitin Feedback studio supports customizable rubrics and grading forms for fair, consistent grading. With Turnitin’s Paper to Digital add-on as part of Feedback Studio, instructors can speed up grading using AI to cluster like responses to grade all at once. Dynamically update rubric scoring and apply it retroactively to previously graded work to ensure fairness. It also facilitates pedagogical best practice such as item analysis to evaluate student performance in relation to test effectiveness.

Paper-based and digital workflows

Amidst digital transformation, there is legitimacy and flexibility in tried-and-true pen-and-paper methods; especially as educators navigate integrity measures in the age of generative AI. For those looking to retain paper-based instruction and assignments but gain the speed and precision of digital grading, Turnitin’s Paper to Digital feature bridges the gap. By enabling the scanning and grading of paper-based assignments and supporting seamless LMS integration, educators can supercharge their productivity to enhance, rather than disrupt existing workflows.

How can similarity detection tools deter plagiarism?

At Turnitin, we’ve developed solutions that both check for text similarity and deter plagiarism. It’s one thing to flag potential plagiarism, but the work of teaching students the value of original writing and proper citation isn’t done with that one step. Educators aren’t police—we are teachers—and our tools should fully support the entire writing process.

Here’s the ideal scenario: the best solution for combating plagiarism is deterrence and to turn instances of plagiarism into opportunities to facilitate original thinking.

It’s an ambitious goal—and we know that many of these “ivory tower” pedagogical notions are not realistic. But we’re trying to bridge that gap between ideals and reality. Yes, teachers want a way to check for plagiarism, full stop. But—what if—what if there was a tool that not only checked for plagiarism but could provide ongoing support to students and teachers to move towards original ideas and thinking?

Teachers are used to providing scaffolding to our students. But what if—what if—teachers had scaffolding in the form of software? What if there was software out there that checks for similarity, but also provides students with formative learning opportunities that lead to success in writing and beyond?

To put it simply, if you are looking for a plagiarism checker that upholds writing pedagogy, here are some questions you should ask yourself before choosing a solution for your institution:

• Does the service allow teachers to provide feedback on student work flagged as potential plagiarism?
• Does the service offer automated feedback to help students with revision? Plagiarism checking is important—but more important is to deter it by providing scaffolding and feedback throughout the writing process.
• Does the service only police or does it facilitate student growth? Can students use the service to improve their drafts and address citation or paraphrasing issues before submitting final work?
• Is the service grounded in best practices for teaching and learning? Does the service provide any classroom resources beyond the product itself? Does the service help teachers address skill gaps that can lead to plagiarism?

It’s time to find out.

Definition of Plagiarism

But before checking for plagiarism everyone should know, What Is Plagiarism?

“The act of pretension where you take one’s words and make them your own it can include ideas, thoughts, or any material that you can see/hear and make a copy of.”

If we talk in a legalistic manner then taking someone’s copyright and claiming it to be yours is unintentional plagiarism.

Self-Plagiarism

The concept of thinking that, self-plagiarism is only copying some other's paintings or borrowing someone else's unique idea. In my thoughts like "copying" and "borrowing" can cover the seriousness of the offense.

According to the Oxford Dictionary Plagiarism is:

“The practice of taking someone else's work or ideas and passing them off as one's own”

In precise words, plagiarism is an act of fraud. It involves both stealing someone else's artwork and lying approximately it in a while.

What is Plagiarism?

Plagiarism is essentially the “imitation of someone else’s work” without giving them their due credit.

Wikipedia defines plagiarism as the “wrongful appropriation” and “stealing and publication” of another author’s “language, thoughts, ideas, or expressions” and the representation of them as one’s own original work.

Examples of Plagiarism

There are dime a dozen examples of plagiarism and some of them are as follows:

• copying someone else’s work without citing them properly,
• paying an external writer/essay mill to write the essay on your behalf,
• stealing ideas and verbal conversations (overheard during discussions etc) and presenting them as your own,
• copying data from websites, library books and other sources verbatim,
• using someone else’s images, music, videos and even style of writing in your own work without their explicit permission is a punishable plagiarism example.

What Are the Different Types of Plagiarism?

Plagiarism can commonly be divided into 5 types. They are as follows:

• Direct plagiarism: Copying someone’s work verbatim (word by word) without giving credits.
• Self-plagiarism: Copying or producing an assignment influenced by your own previous work (also called unintentional plagiarism).
• Mosaic or patchwork plagiarism: Quoting someone else’s work without quotation mark or changing the language (of original work) while keeping the structure same.
• Accidental plagiarism: Unintentionally forgetting to cite the original work, misquotation etc.
• Outsourcing: Paying essay mills, friends, hiring article writers, bloggers to write on your behalf.

FAQs About Plagiarism Detection Tools

1. are free plagiarism checkers efficient enough.

No. No matter what the plagiarism software or plagiarism website tells you on the face, free plagiarism checker tools are not half as efficient as paid ones. If you see, most free versions of plagiarism checkers have a upsell to a paid plan. That’s why free plagiarism checkers are not efficient.

2. Are Premium Plagiarism Checkers Worth The Money?

Yes. Premium plagiarism checkers provide a plethora of tools and features like Deepsearch, checking for contextual plagiarism, multiple file uploads, single institutional account for multiple usernames, analytics, etc.

If you’re a teacher scanning students’ submissions and find duplicate content, you can take action against this academic dishonesty based on the level of copied content. In serious instances, you could terminate the student from school (or as your official manual says). If you’re a website owner and find someone copying your website, you can file a DMCA takedown notice. Alternatively, you can file a Google Copyright Removal which is free and hassle-free. It also gives you the liberty to file a lawsuit against copyright infringement.

4. Is plagiarism similar to copyright infringement?

No, plagiarism is not similar to copyright infringement. The latter is more bound by legal procedures and is taken as a criminal offense. However, plagiarism is considered dishonesty and might lead to a criminal offense in certain cases.

5. Did I plagiarize?

To know if you plagiarized or not, simply scan your document through any of the above online plagiarism checker tools and notice the result. A plagiarism report of 10% or low is generally not considered an offense in academic plagiarism. If it exceeds more than that, you have to double-check your document to see if you copied content or forgot to cite them properly.

6. Can I copy text from Wikipedia?

Yes, as long as you cite the source accurately giving credit where it’s due, you can use text from Wikipedia in your writing. Wikipedia’s content is licensed under Copyleft ( CC-BY-SA & GNU Free Documentation License or GFDL) which means you are free to reuse and modify as long as you attribute the source.

The one tool that I have used over the past decade is Copyscape. I like the premium version though as it allows me to copy/paste the entire article and check for duplicates.

I still haven’t used Grammarly, that is on top of my things to do, and will surely check it out soon.

You’ve neatly explained about copying content and yes, it is a big headache for bloggers. I have many bad experiences with content copying and If found any, I politely request the blog owner to remove that. Some bloggers accepted to delete that type of content but few of the bloggers didn’t worry with it. I don’t have any issues but they will hit by Google animals soon.

Since I’d started blogging a year back since i was new and wasn’t aware of do’s and don’t of blogging and faced such problem. I was only aware of copyscape and smallseotools that i came to know later on as i was searching learning. Since copyscape tell the overall site Plagiarism Check moreover with a number of limited searches being new and having highly copied content it was difficult.

Hello Swadhin,

Plagiarism is worst thing in internet world because many peoples steal contents as well as other’s work without prior permission and used as own work. The original author or owner doesn’t aware about it so above free tools are really useful for them to protect their own work.

Hi Gangadhar, Its true. Its not only disappointing for the owner but also cheating for the readers and viewers who think they are looking at a original piece. Thanks and glad you liked the post. Have a happy week

Hi Swadhin, Thank you so much for this post. You have right timing bro. I was looking for a perfect, free online plagiarism checkers. During the time, I just visited your blog and saw this latest post. This one seems it is exclusively written for me. Thank you so much bro. Among the list, I tried more than 5. Some tools demand to sign-up while others can’t check for plagiarism if the text we enter is a bit longer. So after the fruitless tries, I found Small SEO Tool’s plagiarism checker more useful and it shows how much unique our content is on the basis of percentage. I used it and I am completely satisfied with it. Keep going bro. Regards, Rahul

Hi Rahul, thanks for the kind words. Glad my post was on time to help you. I also think smaalseotools to be a better option and many bloggers use them too. I think plagiarism tools that do not ask for sign ups are great but I would not hesitate giving them my id. In fact I have a rough id for all those sign ups :)

These tools are handy Swadhin. I use copyscape premium version and that is working fine. Free ones are good too. The list is huge and one can find the plagiarism tool of their choice. Nice write up with a great list.

Hi Atish bro, thanks for saying that. Ohh wow you use copyscape premium version for protecting your online content? Thats so good to here. I rarely have seen people invest in such a thing and they should invest in such useful plagiarism detection tools.

That was an informative post indeed :)

I think you covered up everything one wanted to know about plagiarism very well in this post, and it is a great resource for bloggers, new and old. I liked the way you started the post, with the very basic of what is plagiarism, it’s kinds, and the best free tools, and then the paid ones too – you know I like that kind of format myself :)

Yes, you are right – with so many blogs coming up each day, it’s tough for bloggers to be original, and that can only happen if you visit less blogs and write on your own. Yet, for new bloggers that’s not easy, as they tend to read and then learn the right ways, and it’s a process that takes place slowly. We cannot really blame them for they don’t know, till they reach a certain stage in their blogging career. I guess giving due credit to the post author is the right way, even if you take a few pieces of text from the original post.

Honestly speaking, many people copy our posts too, but they are kind enough to link back or put up the original authors names, and all this your Google analytic also shows you, as you don’t always get the pingbacks.

Nevertheless, these are a great list of plagiarism checker tools, and I’ve used most of these, being a freelance writer also, and now of course when one’s blogging also. More than your own posts, it’s the guest posts one needs to scan through, especially if you don’t know the person. I hadn’t heard of the WordPress plugin for checking plagiarism, though it’s not been updated for a while now and not many downloads too. Yes, Copyscape is a good paid option, so is Whitesmoke as I’ve seen many writers use these, though we could always use the free options as and when needed. I know Grammarly has a great one too.

Thanks for sharing this with us. Have a nice week ahead :)

Hello Harleena maam, Thank you maam for the appreciation, I thought to have a post that in a way tries to answer most (if not all) questions writers have . I am learning all these formatting from you and other good blogs. So yes I am still learning to craft the perfect blog post.

Yes maam, we cannot just blame anyone and end the game. The novice bloggers are doing so becuase they aren’t aware about it. But then there are some that do it as a profession. The article spinners and the content mills produce these type of original content and harm both the owner’s credibility and the readers’ trust. I must admit, I was unaware Google analytics have this kind of feature. updates of plugins is not seriously a factor as I had recently read in a post. But yes whitesmoke and grammarly are great option. Copyscape is fantastic if we shell a few dollars. :) Have a great week maam :)

A really huge list of Plagiarism checker tools. All these are very useful. I’m using Small SEO tools from a long time and think most of the bloggers use the same.

No doubt Grammarly is best choice for those who are looking for Grammar checker, a proofreader and plagiarism checker, all in one tool. Although it’s paid tool but free version also offer some good service.

Thanks for sharing these 20 tools list here. I’ll also update my post :D ~ Ankit

Hello Ankit bro, welcome over here, am glad you liked the post. Yes small seo tools is what most use even I do it sometimes. Hahaha I did not know you have a post on plagiarism checker tools also :)
