Check Source Code for Plagiarism

Find unoriginal code and software similarity with the most advanced plagiarism detection solution. Investigate potential copied code by highlighting similarities to billions of sources on the web or from submitted peers.

Smart algorithms

Codequiry looks beyond the cosmetics, finding similarities in logic patterns and unique style of code. Altering variables, whitespace, function names, comments, or many other cosmetic features will not affect overall similarity results. Our algorithm is constantly self-improving.

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 code submissions are original. Put a stop to code copying from peers or the web.

Extensive code checking

Codequiry compares code submissions both internally and externally. First, submissions are extensively checked against one another with our comprehensive peer to peer check. Then, submissions are checked against billions of sources of code on the web.

Language compatibility

Codequiry works with the majority of popular programming languages: Java, C, C++, Python, C# and Plain Text. More languages are constantly being added.
