FAQ

Common questions from educators

What makes Codequiry Desktop enterprise-grade?

Codequiry Desktop provides enterprise-grade accuracy trusted by 500+ universities. Unlike MOSS which has usage limits and requires email approval, Codequiry Desktop gives you unlimited group checks with no restrictions and advanced AI detection capabilities.

How is this better than MOSS or JPlag?

MOSS (1994) and JPlag (1996) are command-line tools that only compare submissions locally. Codequiry Desktop adds:

  • Web plagiarism detection — finds code copied from GitHub, Stack Overflow, and the web
  • AI/ChatGPT detection — identifies AI-generated code
  • Modern GUI — no command line needed, just drag and drop
  • Folder sync — automatically watches for new submissions
  • PDF reports — exportable reports for academic records

Can it detect ChatGPT and AI-generated code?

Yes. Our AI detection engine can identify code patterns from ChatGPT, GitHub Copilot, Claude, and other AI coding assistants. This is essential in 2024+ where students increasingly use AI tools for assignments.

What programming languages are supported?

65+ languages including Python, Java, JavaScript, C/C++, C#, Go, Rust, Swift, PHP, Ruby, TypeScript, SQL, MATLAB, R, and many more. We support virtually every language taught in computer science programs.

How do I check a class of student submissions?

Simply point Codequiry Desktop to your assignment folder. The app will automatically detect all submissions, compare them against each other, check the web for copied code, and flag any AI-generated content. Results are ready in minutes with side-by-side comparisons.

Is my students' code kept private?

Yes. Code is processed securely and never stored permanently. We follow GDPR, FERPA, and university data protection standards. Your students' submissions remain confidential.
