Codequiry - Plagiarism Checker for Code

Prevent Source Code Plagiarism

Find unoriginal code with the most advanced plagiarism detection solution. Investigate potential copied code by highlighting similarities to billions of sources along with peer submissions.


Our modern solution to a modern problem is powered by artifical intelligence, putting a stop to plagiarised code, while constantly learning and detecting new strategies used by cheaters. Codequiry's AI engine focuses on finding logical similarities, meaning that altering variables, whitespace, function names, or comments will not affect overall results.

Results that matter

Codequiry was built around source code detection, this means the results you get are meaningful and reliable. Submissions undergo rigorous checks (more) to ensure that students' codes are original. If a submission is flagged, chances are something suspicious is going on!

Peer and Web comparisons

Compare with Peer Check (get similar matches and visual tools for a group of submissions) as well as Database and Web Check (compare submissions against over 100 million sources in our database or over 2 billion sources live on the web)!

Language compatibility

Codequiry works with the majority of popular programming languages. Additional languages and updates are constantly being added.

The results speak for themselves

Codequiry's results are extremely detailed and allow you investigate any suspicious copying.
