About Codequiry

We're a small team building tools to help educators detect code plagiarism more effectively.

Started in 2018, we've been working to solve a real problem that many computer science instructors face every day.

Why we built this

Like many computer science instructors, we struggled with detecting code plagiarism in our classes. Existing tools were either too expensive, too slow, or just didn't work well enough for the volume of assignments we needed to check.

So we decided to build something better. Our goal was simple: create a tool that actually helps teachers spend less time worrying about plagiarism and more time teaching.

We started small, working with a few universities to understand what educators really needed. Over time, more schools began using our system, and we kept improving it based on their feedback.

How it works

Our system compares student code submissions against several sources to find potential matches:

  • Other student submissions in the same class
  • Code posted on websites like GitHub and Stack Overflow
  • Previously submitted assignments from past semesters
  • Common coding tutorial sites and forums

When we find similarities, we show instructors exactly where the matches are and how similar the code is. This helps them decide whether it's likely plagiarism or just students using similar approaches to solve a problem.

Programming languages we support

We work with most common programming languages that are taught in computer science courses:

Python Java C/C++ JavaScript C# PHP Ruby Go Swift Kotlin Rust MATLAB R SQL and others

Need support for a language we don't have yet? Just let us know and we'll see what we can do.

The challenge we're solving

Computer science instructors have always struggled with code plagiarism. With so much code available online and large class sizes, it's nearly impossible to manually check every assignment for copied work.

Traditional tools like MOSS were designed for smaller classes and don't handle modern programming practices well. Many are also difficult to use or have long waiting times.

We wanted to build something that works better for today's computer science education environment.

What instructors tell us

"I can finally focus on teaching instead of spending hours trying to figure out if students copied their code."

— Computer Science instructor at a large public university

"The web scanning catches things I would never find on my own. It's really opened my eyes to how much copying happens."

— Programming course instructor

"Setup was straightforward and the results are easy to understand. My TAs can use it without any training."

— CS department head
