Best plagiarism checker

The Scribbr Plagiarism Checker has been named the best plagiarism checker of 2019.

It detects more plagiarism than any other plagiarism check and is highly accurate. Compared to other plagiarism checkers, the report contains fewer false positives, which saves students time.

Plagiarism report preview - turnitin similarity report

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.

Frequently asked questions

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 many other free 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.

When should I use the Own Sources Checker instead of the Scribbr Plagiarism Checker?

The Scribbr Plagiarism Checker compares your document against the largest plagiarism database in the world. It will detect any similarities with documents in that database.

However, you might be unsure if all of the sources you used are in that database – for example, because some of your sources are unpublished. In this case, you can make use of our Own Sources Checker. Here you can add all the sources you want to a private database and compare them with your own document.

How long does the Scribbr Plagiarism Check take?

The Scribbr Plagiarism Checker needs approximately 10 minutes to process your document. This time is needed to compare your paper with a massive database with billions of web pages and publications. Documents larger than 35.000 words can take a bit longer.

We will send you an e-mail when the check is finished!

Can I check my document for plagiarism multiple times?

The Scribbr Plagiarism Checker will only check your document 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.

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 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.
