Uphold Academic Integrity in Code
The Only Real Code Plagiarism Protection
Patented Code Plagiarism Technology
Never Seen Before
Fostering Authentic Learning
In Every Classroom
Ensure originality in source code with comprehensive similarity detection across web sources, AI-generated content, and peer submissions
Your Existing Tools are Failing
As educators, you've seen the landscape change dramatically. AI tools, vast online repositories, and new collaboration patterns mean traditional detection methods now only tell part of the story.
The Web Is Everywhere
GitHub, Stack Overflow, and tutorial sites offer instant solutions. Peer-only comparison tools simply can't identify code sourced from these billions of pages.
AI Changes Everything
ChatGPT and Copilot generate unique, syntactically correct code on demand. Each output is different—making similarity-based detection ineffective.
Time Is Precious
Manually reviewing hundreds of submissions isn't sustainable. You need tools that scale with your class size without sacrificing thoroughness.
Turnitin can't check source code
We built Codequiry because we realized traditional plagiarism tools like Turnitin were never designed for programming assignments. They work great for essays—but source code has syntax, logic, and structure that requires specialized analysis.
CS education needed its own solution. So we built one.
Purpose-Built for Code
Variable renaming, function reordering, obfuscation—we detect what text-based tools miss.
Scans the Entire Web
GitHub, Stack Overflow, Chegg, GeeksforGeeks—see exactly where code came from.
Detects AI-Generated Code
ChatGPT and Copilot generate unique code every time. Our AI engine identifies it.
The only platform with complete detection coverage
Three specialized engines working in harmony. Each purpose-built to verify originality across different sources—together they ensure complete coverage.
Compare submissions within your class to identify similar code patterns. Detects renamed variables, reordered functions, and structural similarities across submissions.
Real-time scanning across 40+ billion web sources. Identifies matches 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. Clear documentation for academic integrity reviews.
Visual Clustering
Interactive 2D diagrams that reveal collaboration patterns at a glance. Visualize submission relationships, identify unexpected similarities, and understand how code was shared.
AI Code Detection
Machine learning models trained to identify ChatGPT, Copilot, and AI-generated code patterns. Updated weekly as AI models evolve. Sees what humans can't.
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. Complete transparency for fair conversations with students.
Public API
Powerful REST API for custom integrations. Build your own workflows, integrate with your systems, and automate code checking at scale.

Why educators love us
Trusted by 500+ institutions worldwide
"I came across Codequiry through an ad, but it proved as a life saver in my CS course. I had no way to check if students were submitting original source code, now I do. And the results are amazing."
"MOSS kept timing out on large submissions. Switched to this and haven't looked back."
"The web scan found a Chegg solution I didn't know existed. Student had copied it almost line for line. Would've missed it completely otherwise."
"Makes the awkward conversations easier. I can just show them the report instead of arguing about it."
"Works with Canvas which was the main thing for us. Students submit like normal, I get the reports. Simple."
"Used MOSS for years but it couldn't catch web plagiarism at all. Students figured that out fast."
"Been using it 2 years now. Solid. Does what it says."
"Love that I can exclude my starter code. Used to get tons of false matches because everyone had the same template."
"I'm just a TA but this makes my life so much easier. The side by side view is really clear."
"Found a ring of 6 students sharing code. The clustering thing made it obvious immediately."
"Support actually responds. Had an issue, they fixed it same day. Refreshing honestly."
"MOSS was free but the hassle wasn't worth it. This just works without the email back and forth."
"The AI detection helped us catch a few ChatGPT submissions early in the semester. Good heads up."
"Moved from MOSS after students started using ChatGPT. MOSS has no idea about AI generated code."
"The reports are way better than MOSS. Actually looks professional when you have to show admin."
