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.

Necessity of AI Plagiarism Checker Over Time

DupliChecker's AI plagiarism checker utilizes artificial intelligence to enhance the precision of detecting plagiarism by analyzing various text elements, such as syntax, writing pattern, tone, and rhythm of words. This inclusion of AI simplifies to check AI plagiarism across different domains.

This entire method differs from traditional plagiarism detection methods that use string-matching techniques and provide an approximate estimation of plagiarism that needs to be more accurate.

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.

10 Best Free Plagiarism Checkers | Tested & Reviewed

Published on January 8, 2024 by Koen Driessen . Revised on July 10, 2024.

To find the best free plagiarism checker, we extensively tested and reviewed all popular tools to answer questions like, “How much plagiarism can they detect?” and “Are they actually free?”

Table of contents

Research methodology, general conclusions: free vs. paid checkers, 1. scribbr review, 2. quetext review, 3. duplichecker review, 4. small seo tools review, 5. pre post seo review, 6. grammarly review, 7. plagiarism detector review, 8. check-plagiarism.com review, 9. search engine reports review, 10. plagiarismchecker.co review, frequently asked questions about plagiarism checkers.

The plagiarism tools in this research are tested using 4 test documents , ranging from unedited to heavily edited.

Each test document consisted of plagiarized sections from 140 sources like Wikipedia articles, news articles, open-access journal articles, websites, theses and dissertations, and PDFs.

This setup allowed us to analyze:

• The reliability of plagiarism checker tools, even when texts are edited to varying degrees
• The depth and breadth of the tools’ content databases (whether they only covered websites or also journal articles)

Read more about the research methodology

We found that free tools were frequently misleading in their advertising and were lacking in many ways compared to paid ones. Our research led to these conclusions:

• Offers a limited free version
• Finds far more plagiarism than other tools
• Detects plagiarism even in edited texts
• Won’t store or sell your documents
• Money-back happiness guarantee, with live support available
• Self-Plagiarism Checker feature allows you to check for self-plagiarism

Scribbr offers a limited free version that’s perfect for checking if your paper contains potential plagiarism. To view the full report, you need to buy the premium version, which costs between $19.95 and $39.95 depending on the word count. There’s no word limit, so you can upload as big a document as you want.

Scribbr’s checker, developed in partnership with Turnitin, heavily outperformed all free and paid tools in terms of the amount of plagiarism detected: 83% vs. an average of 42% across free tools.

It performed particularly well with source types relevant to students, such as journal articles and dissertations. Importantly, Scribbr was far more successful than other tools at detecting plagiarism in heavily edited texts, showing it has no trouble with paraphrasing plagiarism.

Scribbr could also consistently provide full matches instead of partial ones, matching the whole plagiarized passage to the correct source.

You see your results in a straightforward downloadable report. Different sources are highlighted in different colors, making it more readable.

The issues identified can be fixed with Scribbr’s Citation Generator , generating correctly formatted citations wherever they are needed.

In addition, Scribbr offers a Self-Plagiarism Checker . This unique tool allows users to upload their own unpublished documents in addition to the public database, to detect any possible self-plagiarism.

However, you can’t edit your text directly in the tool, and it’s not possible to re-check your document for free.

Trustworthiness

Scribbr will not store, sell, or share your uploaded documents. Data is automatically deleted after 30 days, or students can opt to manually delete their document after the check.

Live customer support is offered in multiple languages to assist users. A guide and other resources explaining plagiarism issues are easily accessible.

Scribbr also has a happiness guarantee: if you’re not satisfied with the tool for any reason, you can ask for a new check or a refund.

• Built-in citation assistant helps to add missing citations
• Documents not stored in database
• Support options available (but no live support)

Quetext offers a free trial of 500 words, after which users must pay for a premium plan.

Additionally, uploading files to Quetext is a Pro feature. If you don’t pay, you’ll have to copy-paste the text from your document instead.

The paid version costs at least $8.25 per month (more expensive plans are available), which allows you to check up to 100,000 words.

Quetext detects more plagiarism (49% on average) than any free tool, but it’s unable to match each source text fully to a single source. Different sentences are attributed to different sources.

While Quetext claims to check against academic sources, we found it didn’t perform well at identifying plagiarism from sources such as journal articles and student dissertations.

Quetext’s plagiarism report is relatively straightforward to understand and provides a useful overview. A precise percentage is shown, with similarities in the text highlighted.

However, different sources are not highlighted in different colors, making the report somewhat difficult to read. Instead, orange highlighting is used for partial matches, red for full matches.

There’s also a built-in citation assistant that can help you fix plagiarism by adding citations. Unfortunately, it’s not very robust. Citations generated this way may not be accurate, and you have to add a lot of information manually.

Quetext states that it doesn’t save your text to a database and that all text submitted remains private and encrypted.

Information about the service is available in the form of FAQs on the website, and it’s also possible to contact the company by submitting a request form.

Check out Quetext

• Free (1,000 words per scan)
• Doesn’t save uploaded documents
• Relatively user-friendly reports
• Distracting ads for other services
• Low level of plagiarism detected
• Performs very poorly with edited text
• No color coding for different sources

DupliChecker’s service is free, though you can only upload 1,000 words at a time. If you go for one of their premium plans, you can go up to 25,000.

If you do want to upgrade, a large number of different premium plans are offered on the site, which can be somewhat confusing to navigate. The cheapest is $10 a month.

The level of plagiarism detected by DupliChecker was relatively low (44%).

While the tool was able to find some plagiarism, it was unable to find any full matches. Overall, it performed about as well as other checkers like Small SEO Tools.

DupliChecker’s website is unfortunately full of ads for their other services and for similar sites. A distracting animated “Make it unique” button appears in the report, advertising their rewriting tool.

In the online report, all plagiarized text is highlighted in one color, and it is difficult to figure out what source each source block is matched with.

The site claims not to save uploaded documents, and it deletes content after the check is complete to avoid data leakage. No live support is available, but there is a contact form on the website.

Check out DupliChecker

• Various options for document uploads
• Page is slow, somewhat confusing, and full of ads
• Scans individual sentences rather than full texts

Small SEO Tools is free to use, although you can only check 1,000 words at a time without paying.

You can run multiple checks if you need to scan more than that, although the site requires you to complete CAPTCHAs to upload multiple documents.

Small SEO Tools was unable to identify most plagiarism in our test documents, with an average of only 44%. Since it scans individual sentences separately, it was only ever able to produce partial matches.

Plagiarized text is highlighted (though all in one color), and you can click on it to be shown the source it was matched with.

The page is cluttered with a lot of ads that you can easily confuse with the buttons you need to press.

The report itself is relatively clear. While plagiarized text is highlighted in one color, the tool clearly links matched text with the source identified for it.

Small SEO Tools claims not to store your content after checking it. You don’t have to register to use the tool. Users can also contact a support email to request their personal data be erased.

Check out Small SEO Tools

• 1,000-word upload limit
• Color-coded highlighting
• Some full matches
• Citation assistant
• Live support option
• Detects a low proportion of plagiarism
• Report is hard to read
• Messy, ad-heavy page design
• Color coding doesn’t distinguish between different sources

It’s unclear whether Pre Post SEO is actually a free tool. While the website claims there’s a search query limit for visitors, the limit is not clearly specified and did not seem to apply when we tested our documents.

You can only scan up to 1,000 words per search and cannot see a complete list of matched sources (instead, you must check them manually). These limits are removed if you sign up for their premium plan, which costs $10 to $45 a month.

Pre Post SEO did find the occasional full match, but in most cases it was only able to find partial matches, like most free checkers. Overall, it performed about as well as tools like DupliChecker and Small SEO Tools.

The page where the checker is hosted is full of distracting and irrelevant ads, making the user experience frustrating.

A different color was used for verbatim plagiarism and paraphrasing plagiarism, but the tool’s judgment was often wrong. Other than that, the same color was used for different sources, which made the report hard to read.

Pre Post SEO states that it does not store or sell your documents. There is a live support option on the site and a form you can use to request support.

• Language and citation assistant available
• Does not sell or share documents with third parties
• Finds a relatively low percentage of plagiarism

Despite the way it’s advertised, Grammarly’s checker is not free. All you can do is see a screen that tells you there’s plagiarism in your text without giving you any details of where it is, how much of it there is, or what the sources are.

After this you’ll be directed to download the Grammarly app and subscribe to their premium service ($30 per month). There’s a limit of 100,000 characters (about 20,000 words) even after paying.

Grammarly was able to find more full matches than most free tools. However, it performed particularly poorly with academic sources and received a low percentage overall, scoring a total of 40%.

As a premium service, Grammarly has a clearer and more visually appealing style than most free checkers. The original formatting of the document remains mostly intact, but the tool uses the same color for all sources, making the results hard to parse.

The subscription also gets you a language and style tool and a citation assistant.

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

The site provides a support page with tips, tutorials, and FAQs, and you can submit a question via a form. Live support is not available.

Check out Grammarly

• Free to use (1,000-word limit)
• Does not store or sell your document
• Technical issues with long documents
• Difficult to match text with sources in the report
• Different sources highlighted in the same color

Plagiarism Detector is free to use and users do not need to register. However, there is a limit of 1,000 words per document. By paying, you can raise this limit to 25,000 words per document.

Plagiarism Detector’s performed about as well as other 100% free tools (40%).

The tool was mostly only able to find partial matches, attributing individual sentences to one or more sources.

Plagiarism Detector’s reports are somewhat difficult to read. The same colors are used for different sources, and hovering over a plagiarized section doesn’t show you the source. Instead, you need to find it in a separate list.

Plagiarism Detector states that it will not store or sell your documents. No live support is available, but there is a help request form.

Check out Plagiarism Detector

• Offers a citation generator
• Difficult to match text with sources in the downloadable report
• Scans sentence by sentence —rarely gets a full match

It’s unclear whether Check-plagiarism.com is actually free. The site describes the free upload limit in a confusing way, allowing you a certain number of “queries” (sentences) per month. However, these limits are not clearly specified and did not seem to apply when we tested our documents.

Check-plagiarism.com performed slightly worse than most 100% free tools, scoring a total of 39%.

While the tool was able to find some full matches, it mostly found partial matches.

The same color was used for different sources, which made the report hard to read. A different color was used for verbatim plagiarism and paraphrasing plagiarism, but the tool was often wrong.

You can check up to 1,000 words at once for free. 

In the downloadable report, the format of the text is mostly retained. The report provides a long list of sources that are difficult to cross-reference with the text above.

The version of the report shown on the site itself is slightly better, as a box next to the plagiarized text allows you to see the text identified as the source. There is a “rewrite” function, along with a (manual) citation tool.

Check-plagiarism.com claims that the reports generated on their site are “highly secured and un-accessible.”

There are some FAQs listed on the site, but the answers provided are not very clear. They have live messaging support along with a contact form.

Check out Check-plagiarism.com

• Genuinely free for most purposes (1,000-word upload limit)
• Lots of distracting ads
• Unable to find most of the plagiarism
• Same highlight colors for different sources

Search Engine Reports is free to use, and users do not need to register. However, there is a limit of 1,000 words per scan. By paying, you can raise this limit to 30,000 words per scan.

The methodology this tool uses to find matches appears highly unreliable. It seems to simply search Google for each sentence in your document, counting it as plagiarism if it finds a match.

It identified only a low proportion of the plagiarism (38%) in our test documents. Due to its methodology, it was usually unable to find full matches, and it performed particularly poorly with scholarly sources such as dissertations and journal articles.

The report shown on the site gives a list of individual sentences marked as plagiarized or original. You can click a link next to each source, but all it does is google the sentence in question. The downloadable report highlights plagiarism within the text and shows a list of sources, but it doesn’t clearly link each sentence with a source.

There is also a language statistics function that lets you see words that appear frequently in the text to help limit repetition.

Search Engine Reports claims not to store any uploaded content in their database. There is no live support, but there is a contact form.

Check out Search Engine Reports

• Uploaded documents not stored/sold
• Detects a very low amount of plagiarism
• Misleading about costs—only free for five documents
• Low word limit of 800
• Lots of distracting ads and pop-ups

The tool claims it’s free, but it actually only allows you to upload five documents before requiring you to sign up for one of their many premium plans. These documents have an unusually low word limit of 800.

The premium plans offer options to increase (but not remove) this word limit. The cheapest is $15 per month, which only increases the limit to 1,000 words—a limit many other tools offer for free.

Plagiarismchecker.co gave some of the worst results out of all the checkers we tested, with an average of 30%. It was never able to provide a full match for a source text, only partial.

The tool is frustrating to use due to the high number of ads it displays and the low word limit.

The downloadable report sometimes didn’t include the plagiarism percentage, making it impossible to know how much of the text was plagiarized/original.

The report itself is difficult to read. All plagiarized text is highlighted in one color and is not clearly matched with the source identified for it.

The site claims that uploaded content is not stored in a database or shared with others. It also claims that “our advanced AI-powered algorithm ensures that your content must be protected under the copyright laws.” It’s not clear what this means.

While the site claims to have 24-hour support, there is no live support. There is a contact form on the site.

Yes, Scribbr offers a limited free version of its plagiarism checker in partnership with Turnitin. It uses Turnitin’s industry-leading plagiarism detection technology and has access to most content databases.

Run a free plagiarism check

If you’re a university representative, you can contact the sales department of Turnitin .

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.

It can be easier than you think to commit plagiarism by accident. Consider using a plagiarism checker prior to submitting your paper to ensure you haven’t missed any citations.

The accuracy depends on the plagiarism checker you use. Per our in-depth research , Scribbr is the most accurate plagiarism checker. Many free plagiarism checkers fail to detect all plagiarism or falsely flag text as plagiarism.

Plagiarism checkers work by using advanced database software to scan for matches between your text and existing texts. Their accuracy is determined by two factors: the algorithm (which recognizes the plagiarism) and the size of the database (with which your document is compared).

Your document will be compared to the world’s largest and fastest-growing content database , containing over:

• 99.3 billion current and historical webpages.
• 8 million publications from more than 1,700 publishers such as Springer, IEEE, Elsevier, Wiley-Blackwell, and Taylor & Francis.

Note: Scribbr does not have access to Turnitin’s global database with student papers. Only your university can add and compare submissions to this database.

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.

How to Check for Plagiarism: Ensuring Your Work is Original

Plagiarism is a serious issue, both in academic and professional settings. It involves using someone else’s ideas or words without properly citing them. Fortunately, there are several tools and techniques available to help you check your work for plagiarism before you submit it.

Here’s a guide to navigating plagiarism checkers and ensuring your writing is original:

Understanding Plagiarism Checkers:

• What they do: Plagiarism checkers are software programs that scan your text against a massive database of web pages, articles, and academic journals. They identify any significant matches, highlighting potential plagiarism.
• Peace of mind: Knowing your work is original reduces stress and avoids accusations of plagiarism.
• Catching unintentional mistakes: Even paraphrasing without proper citation can be flagged, prompting you to double-check your references.
• Not perfect: Plagiarism checkers are powerful, but they can’t catch everything. For instance, they may miss paraphrased content that retains the original meaning.
• Limited databases: Free checkers might have smaller databases, potentially missing less common sources.

Using a Plagiarism Checker:

There are several free and paid plagiarism checkers available online. Here’s a general process for using them:

• Choose a checker: Consider factors like features, database size, and cost. Free options are great for basic checks, while paid services might offer more in-depth analysis.
• Upload your text: Most checkers allow you to copy and paste your text or upload a document file.
• Run the scan: Initiate the plagiarism check and wait for the results.
• Analyze the report: The report will highlight any matches. Review each flagged section carefully.

Beyond the Checker: Avoiding Plagiarism

• Proper citation: Always cite your sources correctly, following the appropriate style guide (e.g., MLA, APA).
• Paraphrase effectively: Don’t simply copy and change a few words. Rephrase the information in your own words, but still cite the source.
• Focus on understanding: The goal of research is to learn and develop your own ideas. Don’t rely solely on copying others’ work.

Plagiarism is a serious offense that can hurt your academic or professional career. To avoid accusations of plagiarism, it’s important to use a plagiarism checker to ensure that your work is original.

Ensuring the originality of your content is essential, and the best plagiarism checkers mentioned above can assist you in avoiding the severe consequences associated with plagiarism.

By considering factors such as content database size, user interface, additional features, and pricing plans, you can select the most suitable plagiarism checker to meet your specific needs. Invest in these reliable tools to enhance your writing integrity and achieve peace of mind.

Many plagiarism checkers are available, so it’s important to choose the right one for your needs. In this article, we’ve compared the best plagiarism checkers of 2024 and helped you choose the one that’s right for you.

We hope this article helps you to choose the right plagiarism tool to check your thesis, research manuscript, and assignments.

No, the Self-Plagiarism Checker does not store your document in any public database.

In addition, you can delete all your personal information and documents from the Scribbr server as soon as you’ve received your plagiarism report.

Scribbr’s Plagiarism Checker is powered by elements of Turnitin’s Similarity Checker , namely the plagiarism detection software and the Internet Archive and Premium Scholarly Publications content databases .

The add-on AI detector is powered by Scribbr’s proprietary software.

Extensive testing proves that Scribbr’s plagiarism checker is one of the most accurate plagiarism checkers on the market in 2022.

The software detects everything from exact word matches to synonym swapping. It also has access to a full range of source types, including open- and restricted-access journal articles, theses and dissertations, websites, PDFs, and news articles.

At the moment we do not offer a monthly subscription for the Scribbr Plagiarism Checker . This means you won’t be charged on a recurring basis – you only pay for what you use. We believe this provides you with the flexibility to use our service as frequently or infrequently as you need, without being tied to a contract or recurring fee structure.

You can find an overview of the prices per document here:

Please note that we can’t give refunds if you bought the plagiarism check thinking it was a subscription service as communication around this policy is clear throughout the order process.

Your document will be compared to the world’s largest and fastest-growing content database , containing over:

• 99.3 billion current and historical webpages.
• 8 million publications from more than 1,700 publishers such as Springer, IEEE, Elsevier, Wiley-Blackwell, and Taylor & Francis.

Note: Scribbr does not have access to Turnitin’s global database with student papers. Only your university can add and compare submissions to this database.

Scribbr’s plagiarism checker offers complete support for 20 languages, including English, Spanish, German, Arabic, and Dutch.

The add-on AI Detector and AI Proofreader are only available in English.

The complete list of supported languages:

If your university uses Turnitin, the result will be very similar to what you see at Scribbr.

The only possible difference is that your university may compare your submission to a private database containing previously submitted student papers. Scribbr does not have access to these private databases (and neither do other plagiarism checkers).

To cater to this, we have the Self-Plagiarism Checker at Scribbr. Just upload any document you used and start the check. You can repeat this as often as you like with all your sources. With your Plagiarism Check order, you get a free pass to use the Self-Plagiarism Checker. Simply upload them to your similarity report and let us do the rest!

This may be accidental. Students, researchers, etc should take precautions while doing that.

There are several different types of plagiarism that should be avoided, as they can lead to embarrassment and loss of reputation.

This is an awesome product. I create promo in a multi-language area, and I'm often tasked with creating pieces that need to be in multiple languages.

I am so excited to see more feature like Translate Speech and more tools like content checker, synonyms and grammar correction tools.

Testimonial 1

I'll be using it a lot, since I work in the publishing industry and we were searching for an accurate tool to translate short stories into other languages. With Multilings, we've been able to do so, and to spend less time "adapting" the translation. It's a lot more intuitive about the context of the phrases than other tools out there. What an app have you created! It`s amazing and works so fast and precisely. Also, tried their customer service, awesome on time experience. I highly recommend Multilings to my friends and coworkers.

Plagiarism Checker FAQ​

Unlocking the Answers: Your Ultimate Plagiarism Checker FAQ Guide

We recommend making your text only 15% or less plagiarized. More than that affects the originality of your work. In some cases when you put references, text, and quotes, you should always use the citation to give full credit to the author of that content.

Deliberate plagiarism is intentionally copying works from websites, e-books, articles, blogs, or someone else’s paper and representing it as your original work. However, accidental plagiarism happens in a few different ways:

• Unknowingly citing another person’s works

• Incapable to paraphrase someone else’s works – even when cited correctly.

• Reusing your own previous papers and inadvertently representing it as a fresh work.

Your reputation in the market can seriously get affected due to copying. The audience will consider you a non-professional who just steals others’ ideas and presents them as your own.

Damaged Career

A content writer might find it difficult to secure his/her job in the market after getting caught with plagiarized data. As a result, your years of hard work can go in vain, and you might not be able to find another job.

Legal Consequences

Depending upon the seriousness of replication you’ve committed, you can face legal issues because of duplication. For example, the original creator of the content might sue you, and as a result, you would have to pay compensation in monetary terms.

Lose website Traffic

If the text on your site’s pages isn’t giving any fresh material to visitors for reading, then they will eventually stop visiting your site. These days, people admire reading something that they haven’t known before. However, the habit of similarity will prevail from attracting the audience towards your site. To prevent yourself from this nuisance use the best plagiarism checker.

Damaged SEO

An authoritative and unique content has a significant role in enhancing the SEO of a website, which eventually leads it towards the top ranking in SERP. However, if the content you’ve uploaded is plagiarized, then it would result in negative SEO. Plus, not only one webpage but the whole website will suffer from a downfall in Google ranking. Check the keywords ranking of any website by using a keyword rank checker.

What is Plagiarism?

Plagiarism means to pass off as new and original an exact idea or product derived from an existing source with or without the consent of the original creator.

According to the Oxford Dictionary "plagiarize" means: “Presenting someone else’s work or ideas as your own, with or without their consent”

Merriam-Webster says: “To use the words or ideas of another person as if they were your own words or ideas”

What Are the Most Common Types of Plagiarism?

The most common types of plagiarism include direct plagiarism, self-plagiarism, mosaic plagiarism, and accidental plagiarism.

Direct plagiarism happens when a writer duplicates another's work without acknowledging that the material came from another source.

Self-plagiarism occurs when someone recycles or reuses their own work from previously published texts as new writing

Unintentional or accidental plagiarism occurs when a writer fails to appropriately paraphrase, quote, or cite without intending to cheat

Mosaic plagiarism or patchwriting occurs when a person overuses quotes without crediting the original sources. This type of plagiarism may indicate a lack of research or proper understanding of the topic

• Paraphrased – text that is rewritten using different words or sentence structures, but the core idea remains the same.
• Omitted – the portion of text that is not being scanned for plagiarism based on the scan settings. (example: the ignore quotations setting is enabled, and the document is 20% quotations = the omitted words percentage is 20%), unhighlighted.

This is a fantastic product and given the income I would definitely upgrade to the premium. I've let all my fellow students know about Trinka as it is seriously a life saver.

Do You Have Further Questions?

What do I need to know for using the plagiarism checker?

The plagiarism checker scans your whole document, looking for plagiarism. This also includes tables and indexes, as it might happen that entire tables or indexes are copied. Small similarities might always exist on work cited pages.

Note: If you do not want the plagiarism checker to scan these parts of your paper, change your document accordingly before you upload your thesis. Check now for plagiarism with our online plagiarism checker .

How long does a plagiarism check take?

A plagiarism check of a bachelor’s or master’s thesis (60-80 pages) normally takes between 10 and 20 minutes. It depends on the number of words submitted. In the case of longer pieces of work (200-300 pages), the plagiarism check can take up to an hour.

Does the plagiarism checker work in other languages?

Yes! The plagiarism check works in all languages. Regardless of the language or if you’re writing a Bachelor’s thesis or a dissertation, the plagiarism checker will work for you. Many of our services here at BachelorPrint are multilingual.

Will the document I upload be saved to a database?

The first step of the plagiarism check is to upload your file. This will be temporarily saved on our server. Then the text content of the uploaded document will be extracted, and your original file will be deleted. In the next step, the extracted text will be transferred to a temporary database and will be divided into individual sections according to language statistics.

The plagiarism checker then reads the individual sections and searches the World Wide Web for matches. In the last step, a plagiarism report will be generated, in which plagiarized areas are marked in color and the link to the original source is given. If you’re not sure why something has been marked as plagiarism, check out our blog post to find out more about what constitutes plagiarism . But don’t worry! Because 24 hours after using the plagiarism checker online, your data will be deleted – completely in line with data protection requirements!

Do I have to register for the plagiarism checker first?

No! It’s incredibly easy! You can just upload your document, choose your payment method, and then use the plagiarism checker without a user account or registering. Start your plagiarism check now.

Which sources will be used by the plagiarism software?

All publicly accessible online sources will be used in the plagiarism check. Databases where payment is required are excluded. If a book is online in a publicly accessible database, then the plagiarism software will also find this source. Have trouble organizing and citing your sources? Take a look at our blog posts. We have APA citation , Harvard referencing , and more.

What’s the difference between the BachelorPrint plagiarism software and Turnitin?

The BachelorPrint plagiarism software doesn’t save any uploaded work for data protection reasons, unlike Turnitin. Accordingly, we don’t rely on the same database as Turnitin.

However, our plagiarism software searches billions of publicly available sources on the World Wide Web.

Information : If the work is scanned for plagiarism in advance with Turnitin, and the university also uses Turnitin, there is a considerable potential risk for the writer. As Turnitin saves the uploaded work, this will then be in their database. If the university scans the same work on it, it will then be classified as complete plagiarism. This has already been heard of a few times. The student’s work therefore failed in the first instance, and they had to prove that they had written the document saved by Turnitin.

I haven't received an email with the plagiarism software. What should I do?

It’s possible that the email from the plagiarism software has gone into your spam folder. In extremely rare cases, our e-mail with the plagiarism report from the plagiarism software might have been blocked by your e-mail provider and haven’t been received. Please contact us at [email protected] . We will resend the plagiarism report right away.

Too few pages are shown in the plagiarism report. Why?

For an overview, only text passages that might contain plagiarism are shown in the plagiarism report. The other pages where no plagiarism is suspected will not be shown. So fewer pages in your plagiarism report is a good sign!

Why is a section marked as suspected plagiarism even though I have cited the source?

It’s possible that a section of text is marked as suspected plagiarism even though it has already been correctly cited, for example from a book. This happens if the software finds a further online source. In this case, the suspected plagiarism can be ignored and this serves merely as extra peace of mind. To learn more about properly citing your sources, read our blog post about how to cite a book .

Why should I use the online plagiarism software?

It mostly happens unintentionally. Mistakenly. Unknowingly. Due to time constraints. Even though every single student knows, or should know, that every source from a different author must be identified in an academic paper. Not complying with this principle is committing plagiarism. Therefore, you should use the online plagiarism software just to be sure.

There are well-known examples that indicate how rigorously academia deals with plagiarism. Writers of a Bachelor’s thesis, Master’s thesis, and other academic work didn’t have to fear being disqualified from their Ph.D. program or even public exposure. However, this is of little consolation to someone who has failed their bachelor’s thesis because of a few “forgotten” citations.

Extremely satisfied, excellent deal with delivery in less than 24h. The print...
