Avoiding accidental plagiarism

You don't need a plagiarism checker, right?

You would never copy-and-paste someone else’s work, you’re great at paraphrasing, and you always keep a tidy list of your sources handy.

But what about accidental plagiarism? It’s more common than you think! Maybe you paraphrased a little too closely, or forgot that last citation or set of quotation marks.

Even if you did it by accident, plagiarism is still a serious offense. You may fail your course, or be placed on academic probation. The risks just aren’t worth it.

Scribbr & academic integrity

Scribbr is committed to protecting academic integrity. Our plagiarism checker software, Citation Generator, proofreading services, and free Knowledge Base content are designed to help educate and guide students in avoiding unintentional plagiarism.

We make every effort to prevent our software from being used for fraudulent or manipulative purposes.

Frequently asked questions

See all
Will my sources/document be stored in a (shared) database?

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.

What plagiarism and AI detection software does Scribbr use?

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.

How accurate is Scribbr’s plagiarism checker?

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.

Can I buy a monthly subscription for the Scribbr Plagiarism Checker?

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:

Small document (up to 7,500 words) $19.95
Normal document (7,500-50,000 words) $29.95
Large document (50,000+ words) $39.95

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.

To which databases will my document be 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.

What languages are supported by the plagiarism checker?

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

Will Scribbr give the same result as my university’s plagiarism checker?

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!

Can other plagiarism checkers see my submissions to Scribbr?

Your writing stays private. Your submissions to Scribbr are not published in any public database, so no other plagiarism checker (including those used by universities) will see them.
