Protect Academic Integrity in Source Code
Our Hexagram plagiarism engine is purpose-built for code and detects every form of inauthentic writing—AI-generated code, web plagiarism, and peer collaboration. No matter the source, we catch it all.
Your current tools are completely blind
MOSS, JPlag, and SafeAssign were built in a different era. They only compare submissions within your course—completely missing code copied from the web or generated by AI. Your students know this.
Zero Web Detection
Legacy tools can't scan GitHub, Stack Overflow, Chegg, or any web source. Students copy freely from millions of online repositories.
No AI Detection
ChatGPT, GitHub Copilot, and Claude generate unique code every time. Traditional tools see 0% similarity for AI-generated submissions.
Outdated Technology
MOSS hasn't been updated since 2003. Students share workarounds on Discord and Reddit. The game has changed—your tools haven't.
The only platform with complete detection coverage
Three specialized engines working in harmony. Each purpose-built to catch different forms of academic dishonesty—together they miss nothing.
Our proprietary tokenization algorithm for peer-to-peer comparison. Catches renamed variables, reordered functions, and sophisticated obfuscation attempts that fool other tools.
Real-time scanning across 40+ billion web sources. Catches code copied from GitHub, Stack Overflow, Chegg, GeeksforGeeks, and millions of code repositories worldwide.
High-speed AI detection with our advanced algorithm. Identifies ChatGPT, GitHub Copilot, and AI-generated patterns in milliseconds. Updated regularly to stay ahead of new AI models.

Everything you need to protect academic integrity
Purpose-built for computer science education. Not a text plagiarism tool with code features bolted on—a true code-first platform.
Side-by-Side Comparison
Line-by-line diff viewer with syntax highlighting, similarity scoring, and one-click navigation between matched sections. Crystal-clear evidence for academic hearings.
Visual Clustering
Interactive 2D diagrams that reveal cheating clusters at a glance. See who copied from whom, identify study groups gone wrong, and spot contract cheating patterns.
AI Code Detection
Machine learning models trained to identify ChatGPT, Copilot, and AI-generated code patterns. Updated weekly as AI models evolve. Catches what humans can't see.
10-Minute Results
Cloud-powered analysis across billions of sources delivers comprehensive reports while you wait. Process 500 submissions in under 10 minutes. No queues, no waiting.
Source URL Tracking
When we find a match, we show you exactly where it came from. Direct links to the source page, file, or repository. Undeniable evidence your students can't dispute.
Public API
Powerful REST API for custom integrations. Build your own workflows, integrate with your systems, and automate code checking at scale.
