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.

What payment methods do you accept?

We accept the following payment methods:

Credit card (Visa, MasterCard, American Express, Maestro and Diners Club)
Transaction fee of 2% – 3,9%.

Transaction fee of 3,5%.

Transaction fee of 3,2%.

WeChat Pay
Transaction fee of 2%.

No transaction fee.

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 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 compares your document against:

  • Over 60 billion of current and historical web sources.
  • Over 30 million of articles from scientific information sources and journals from the major scientific publishers.

This content database is provided in partnership with Turnitin.

At the result page of your Plagiarism Check you can see in which database the original source is found.
