90% of students bypass
your plagiarism checker
MOSS, JPlag, and other CLI tools were built for a different era. They can't catch web plagiarism, can't detect ChatGPT-written code, and students know exactly how to fool them. It's time for something that actually works.
Your current tools were never designed for today's cheating methods
Tools like MOSS and JPlag only compare submissions against each other. They're blind to the internet, blind to AI, and students have been exploiting these gaps for years.
What outdated tools miss:
- Code copied from GitHub repositories — millions of public solutions
- Answers from Stack Overflow, Chegg, CourseHero
- Code written by ChatGPT, Claude, or GitHub Copilot
- Solutions from past semesters shared between students
Three-layer detection that catches everything
We scan trillion+ sources, compare peers, and detect AI patterns — all in one check.
Peer Comparison
Hexagram tokenization compares all submissions against each other. Catches collaboration, shared code, and copied homework — even with renamed variables.
Trillion-Source Web Scan
Every submission is checked against GitHub, Stack Overflow, Chegg, CourseHero, and billions of indexed code snippets across the web.
AI Code Detection
Identifies code patterns from ChatGPT, Claude, Copilot, and other AI tools. Catches students who use AI to write or "spin" their assignments.
