Frequently asked questions

See all
Will my document be published on a (public) database?

No, the Scribbr Plagiarism Check does not result in your document being published in any public database (unlike other plagiarism checker services).

As soon as you’ve received the result from the Plagiarism Checker, you can directly delete all details and documents from the Scribbr server.

Which sources are used for the Scribbr Plagiarism Checker?

The Scribbr Plagiarism Checker, in partnership with Turnitin, compares your document against the largest and fastest-growing content database in the world:

  • Over 70 billion current and historical web pages.
  • Over 69 million journal articles and books from more than 1,700 publishers such as Springer, IEEE, Elsevier, Wiley-Blackwell and Taylor & Francis.

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

In your plagiarism report you can see the database in which the original source is found.

Turnitin Similarity Report

Will I get a 100% match at my school when I use the Scribbr Plagiarism Checker?

We understand this concern. However, since the Scribbr Plagiarism Checker does not store any documents that it checks in a shared database, it’s impossible for this to happen.

As an added precaution, you can also personally delete your details and documents from Scribbr’s own server as soon as you’ve received the results of your Plagiarism Check.

Will the results be the same as the results of the check used at my school?

The Scribbr Plagiarism Checker is optimized for students, which means that you will receive a detailed report with extra information to fix and prevent plagiarism, similar to the report received by your school.

Minor difference

Schools often have their own database of (prior) theses. Scribbr has no access to those databases. When you copy data from another thesis that is not publicly accessible, the Scribbr Plagiarism Checker will neither be able to detect plagiarism nor identify the source of this data.

However, most theses are actually publicly accessible since many universities and schools have public databases. This means that the Scribbr Plagiarism Checker is able to find these theses.

How long does the Scribbr Plagiarism Checker take?

The Scribbr Plagiarism Checker takes about 10 minutes to finish.

For documents larger than 25.000 words it can take a bit longer. You will be shown an estimate at the order overview.

As soon as the check has finished we will also send you an e-mail.

Can institutions buy plagiarism checks for a discounted price?

Yes, if you are interested in buying more than 25 plagiarism checks we can make an offer with a discounted price.

Depending on the size of your request, you will be contacted by a representative of either Scribbr or our partner Turnitin.

Please open our Plagiarism Checker page and click on “Request volume pricing”.


Can I check my document for plagiarism multiple times?

The Scribbr Plagiarism Checker will only check your paper for plagiarism once. Don’t worry – if you have followed our guide, as well as our articles on preventing plagiarism and citing sources, there is no need to perform a second plagiarism check.

Keep in mind that if you try to avoid plagiarism by paraphrasing, you still need to include a reference to the original source.

If you still want to perform a second plagiarism check, you’ll have to buy a new check at the regular price.
