Comprehensive report

Your plagiarism report contains three main elements: a similarity percentage, a list with matched sources and a preview that highlights matched text in your document.

Whereas many other plagiarism checkers can only detect exact matches, the Scribbr Plagiarism Checker also detects patchwork plagiarism.

In other words, our software can detect plagiarism even when you paraphrase sentences or combine multiple sources.

turnitin check percentage

The similarity percentage indicates what portion of your text matches other sources in our database.

The plagiarism software excludes your reference list and other sections where similarities are common but are not actually plagiarism.

Therefore, the similarity percentage is highly accurate.

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 avoid plagiarism, similar to the report received by your school.

Minor difference

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

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.
