As a Software Integrity Specialist at Codequiry, I spend my days helping educators, students, and coding competition organizers ensure that code submissions are original. Whether you’re a student tackling a programming assignment, a professor grading projects, or a developer contributing to a team, the question of code integrity is critical. With tools like ChatGPT generating functional code in seconds, detecting unoriginal work has become trickier than ever. So, how do modern AI code detectors stack up against traditional plagiarism checkers like the Stanford Code Plagiarism Checker (MOSS)? Let’s dive into the mechanics, compare their strengths and weaknesses, and explore what this means for you.
My goal here isn’t to sell you on a specific tool but to give you a clear, technical understanding of how these systems work and how they can help maintain fairness in coding. By the end, you’ll know what to look for in a plagiarism detection tool and how to avoid common pitfalls when writing code.

What Are AI Code Detectors?
The Basics of AI Code Detection
An AI code detector is a tool designed to identify similarities in source code, including code generated by AI models like ChatGPT. Unlike older plagiarism checkers that focus on exact or near-exact matches, AI code detectors dig deeper, analyzing the logic and structure of code. For example, Codequiry’s AI code detector, available at Codequiry’s ChatGPT-Written Code Detector, looks at both peer-to-peer similarities (comparing submissions within a group) and web-based matches (checking against online sources like GitHub or Stack Overflow).
