Built Specifically
for Source Code
Detection algorithms designed for code, not general text,
covering both AI-generated code and programming plagiarism
Purpose-Built Architecture
Unlike generic plagiarism checkers, Codequiry is engineered specifically for code. Our algorithms understand syntax, logic, and structure, not just text.
Multi-Layered Detection
Three detection engines working in parallel: AI pattern recognition, structural analysis, and web source matching.
Lightning Fast
Optimized cloud infrastructure delivers results in seconds, not minutes. Batch process hundreds of submissions instantly.
Trillion+ Code Sources Check
Check against GitHub, Stack Overflow, academic databases, and trillions of web pages. Plus 5TB proprietary database.
Built for Education
Designed from the ground up for educators. Bulk import from LMS, batch processing, team collaboration, and detailed reporting that works for your workflow.
