Extensive testing proves that Scribbr’s plagiarism checker is one of the most accurate plagiarism checkers on the market in 2024.
The software detects everything from exact word matches to synonym swapping. It also has access to a full range of source types, including open- and restricted-access journal articles, theses and dissertations, websites, PDFs, and news articles.
Scribbr’s Plagiarism Checker is powered by elements of Turnitin’s Similarity Checker, namely the plagiarism detection software and the Internet Archive and Premium Scholarly Publications content databases.
The add-on AI detector is powered by Scribbr’s proprietary software.
Your document will be compared to the world’s largest and fastest-growing content database, containing over:
Note: Scribbr does not have access to Turnitin’s global database with student papers. Only your university can add and compare submissions to this database.
Generating your (free or premium) plagiarism report takes between 1 and 10 minutes, depending on the document size.
In that time, your document is compared to the world’s largest content database, with over 99 billion webpages and 8 million publications.
At the moment we do not offer a monthly subscription for the Scribbr Plagiarism Checker. This means you won’t be charged on a recurring basis – you only pay for what you use. We believe this provides you with the flexibility to use our service as frequently or infrequently as you need, without being tied to a contract or recurring fee structure.
You can find an overview of the prices per document here:
| Small document (up to 7,500 words) | $19.95 |
|---|---|
| Normal document (7,500-50,000 words) | $29.95 |
| Large document (50,000+ words) | $39.95 |
Please note that we can’t give refunds if you bought the plagiarism check thinking it was a subscription service as communication around this policy is clear throughout the order process.
Your writing stays private. Your submissions to Scribbr are not published in any public database, so no other plagiarism checker (including those used by universities) will see them.
Scribbr’s plagiarism checker offers complete support for 20 languages, including English, Spanish, German, Arabic, and Dutch.
The add-on AI Detector and AI Proofreader are only available in English.
The complete list of supported languages:
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).
To cater to this, we have the Self-Plagiarism Checker at Scribbr. Just upload any document you used and start the check. You can repeat this as often as you like with all your sources. With your Plagiarism Check order, you get a free pass to use the Self-Plagiarism Checker. Simply upload them to your similarity report and let us do the rest!
