Detect all types of plagiarism

Like many other plagiarism checkers, the Scribbr Plagiarism Checker identifies sentences that are exactly the same as in the original source.

However, it also detects plagiarism in paragraphs where the sentence structure is changed, synonyms are used, extra words are inserted or text from multiple sources is combined.

Frequently asked questions

See all
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).

Luckily, many papers, theses, and dissertations are also published in public databases that Scribbr does have access to.

Which databases will my document be compared to?

The Scribbr Plagiarism Checker, powered by Turnitin, compares your submissions against the largest and fastest-growing content database in the world:

  • Over 91 billion current and historical web pages.
  • Over 69 million publications from more than 1,700 publishers such as Springer, IEEE, Elsevier, Wiley-Blackwell, and Taylor & Francis.

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

Can I check my document for plagiarism more than once?

Scribbr checks your document for plagiarism only once. You can use the “exclude text” feature to exclude similarities that you’ve resolved, which automatically updates your similarity score.

If you would like to recheck your entire document, you can purchase a new plagiarism check at the regular price. We don’t currently offer a subscription service.

Will my submissions be published in a (public) database?

No, the Scribbr Plagiarism Checker does not publish your submissions in any public database (unlike other plagiarism checkers).

Will my teacher or supervisor see my submissions to Scribbr?

No, your teacher, professor, or admissions officer will not be able to see your submissions at Scribbr because they’re not added to any shared or public databases.
