10 Best Free Plagiarism Checkers in 2023 | Tested & Reviewed

Published on June 8, 2023 by Koen Driessen .

To find the best free plagiarism checker in 2023, 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
• You need to go premium to find out your precise similarity score and view the entire report

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.

Quality of matches

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.

Check out Scribbr

• Built-in citation assistant helps to add missing citations
• Documents not stored in database
• Support options available (but no live support)
• Finds partial matches
• Not clear how the free trial works
• Monthly subscription of at least $8.25 after free trial
• Not effective for scholarly sources
• Doesn’t detect all plagiarism

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.

Check out Pre Post SEO

• Language and citation assistant available
• Does not sell or share documents with third parties
• Finds a relatively low percentage of plagiarism
• Same colors used for different sources

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.

The EasyBib plagiarism checker is conveniently available 24 hours a day and seven days a week. You can cancel anytime.  Check your paper for free today!.

Best Plagiarism Checker for Research Papers and Thesis – Free and Paid

If you are writing scientific papers or academic thesis, one of the most critical aspect of your work is avoiding and reducing plagiarism from your papers. In this post we will break down the most useful plagiarism checker for research work and journals. 

The recommendations in this article have a data-base of thousands of papers from medical, engineering and other domains and AI capabilities to offer plagiarism reports.

Recommendation Plagiarism Detectors for Research

• Turnitin (Only registered students and researchers can use it. Not available for public)
• Plagiarism Checker X ( Available in 7 languages including German; Used by top Universities and companies )
• Grammarly ( Grammar checker and Plagiarism detection tool; Now available on Mac and Windows )
• ProWritingAid ( Plagiarism and Grammar error correction; Loved by Millions of Authors, Writers and academicians )
• MOSS (for technical papers to detect similarity in code)

Hunting plagiarism in research papers is more daunting than a personal website or a blog.

Where you can have a fair excuse and the luxury of <blockquote> , which help other search engines to know that you have copied online, you don't have such an option while working on your thesis. Here we are writing about the best software tools to prevent plagiarism in research work.

Plagiarism is unacknowledged copying or an attempt to misattribute original authorship, whether of ideas, text or results.

source: https://www.nature.com/authors/policies/plagiarism.html

There can be multiple ways to plagiarise your hard-worked content. We have already talked a lot about accidental plagiarism and ways to protect it in our previous articles.

You can also test your knowledge by taking a simple plagiarism quiz which will help you to understand and avoid plagiarism in a better manner.

Other is, as you know, intentionally. No matter, how are you messing up with the act, it will be equally offensive.

Steps to Avoid Plagiarism in Research Work

• The best way to stay original is: staying original. Don't get me wrong. All I want to say is, think with your own imagination. Paraphrasing is actually detectable if it is not done properly. Also, if you are doing it, you should not forget to add an in-text citation properly.
• Another important thing is to keep track of your work from the very beginning of your work. You can use cloud services like Evernote and Pocket to keep track of URLs, PDFs, Blogs, Websites, and Other Works.
• 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.

Best Plagiarism Checker Tools for Research and Journals

Without any doubt, Turnitin is a good tool to detect a similarity between the strings, whether it is a research work or an assignment. It has a huge database of research work and it is capable to find similarity in your content with the previous works.

A common myth about Turnitin is that it is a perfect tool. It is Not! Also, it is not a deciding tool   that you have actually plagiarized. Instead, it shows results to your professors for possible similarity among previously submitted work. That depends on the setting teachers are using. Only the examiner and you (human) can judge whether you have plagiarized or not.

Plagiarism Checker X

Plagiarism Checker X is the best alternative to Turnitin for many reasons. It provides some of the coolest features for students and professors. Some of them are bulk uploading, side-by-side comparison, automatic citation and multiple language support. It is the only tool on the planet which provides offline check after two consecutive checks.

You can play with the free version to test the waters before going for a premium one which is also available for less than $40 for a lifetime. It is being used by several universities and top companies as their standard tool.

PlagiarismcheckerX supports All Windows Platforms and you will be required to download .exe file to work with this plagiarism checker for academics.

Grammarly is one of the biggest companies working closely in education and industry. Hundreds of companies, schools, and universities are using Grammarly for proofreading, plagiarism checking, and learning English Grammar. They have a great database and constantly learning algorithms that are becoming better with time.

Not to forget, Grammarly is a safe tool (forget rumors) and they don't sell your data to anybody. With the provided browser extension, Android support, and native applications, it gives much power to you as an academician.

It supports macOS, Android, iOS, Windows, Google docs, and have a web application.

Plagiarisma.net

After a considerable amount of research, I came to the only Free tool which is safe to be used for research work. It uses Google Scholar search results to detect similarities in your content. Plagiarisma.net is able to detect more than 10 billion (as they claim) search engine results and it can be used from their website as well via their Windows application. But take this advice with a grain of salt.

Note that Plagiarisma only supports Windows operating systems.

💯 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.

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

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.

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.

Ultimate Guide to a plagiarism detection tool for Academic Research

Defining plagiarism – types and examples.

Plagiarism occurs when you replicate the thoughts, ideas, and words of another without giving them the credit they deserve . 

So, when you do research online, make sure you 1) cite the source and attribute the credit when it’s due and 2) blend the reference into your own content. 

We have talked about some of the Best Academic Writing Tools here. 

Plagiarism may be classified into several types:

• Plagiarizing from your own work- this is when you copy sections of your own work and offer it as new material.
• Plagiarism from other sources- This is when you copy content from other sources without crediting the original author.
• Paraphrasing without attribution is when you steal someone else’s content and alter the words around, but you don’t give credit to the original author.
• Quoting without attribution is when you utilize someone else’s text without crediting the original author.

All of these sorts of plagiarism are considered cheating and can result in severe penalties. It is critical to understand the many forms of plagiarism and to always give credit to the original author anytime you utilize someone else’s work.

Why pay when there are so many free tools? 

There are several reasons why people would opt to pay for a plagiarism detection program when there are so many free ones accessible. As a researcher myself, my biggest reasons are:

• Accuracy – I want to be able to trust the tool to detect plagiarism in my writing. 
• Ease of use – how easy is it to trace the plagiarism and make the fixes
• Performance – does it tell me who’s content my writing is similar to?

Free tools either have issues with accuracy or are inherently difficult to navigate. Also, most of them do not show the source of plagiarism. 

Other than these, you may also consider the following. 

What features should you look for in a plagiarism checker tool?

When looking for a plagiarism checker tool, you should consider the following features:

1. Ease of use – The plagiarism checker tool should be easy to use, with a user-friendly interface.

2. Accuracy – The plagiarism checker tool should be accurate, and be able to detect plagiarized content quickly.

So what’s the best way to avoid plagiarism and make sure your research paper is up to the desired standards? Use a plagiarism checker tool, of course! There are a number of different plagiarism checkers out there, and each one has its own strengths and weaknesses. 

But no matter which tool you choose, using it is better than not using it at all. Have you tried using a plagiarism checker for your research papers? If not, now might be a good time to start. Let us know in the comments which plagiarism checker works best for you.
