How Burstiness and Perplexity Catch AI-Generated Code

Burstiness and perplexity aren't just linguistic curiosities—they're the primary statistical signals that distinguish human-written source code from LLM output. This article explains exactly how these measures work under the hood, with worked examples, real-world detection rates, and honest limitations.

A Checklist for Evaluating AI Code Detection Tools

Not all AI detection tools are created equal, and a single "accuracy" number is dangerously misleading. This article provides a practical, seven-point checklist for evaluating AI-generated code detectors, covering everything from cross-language support and prompt sensitivity to campus-specific deployment constraints.

Your AI Detection Tool Is Probably a Random Number Generator

The market is flooded with tools claiming to spot AI-written code with 99% accuracy. Most are built on statistical sand. We dissect the eight fundamental flaws, from dataset contamination to meaningless confidence scores, that render their outputs little better than a coin flip for serious applications.

Your AI Detection Tool Is Missing These 8 Code Patterns

AI-generated code is evolving past simple pattern matching. The latest models produce code that passes basic similarity checks but reveals its origin through deeper, more subtle signatures. We dissect eight specific, often-overlooked patterns that separate human logic from machine-generated output.

Your Students Are Using AI and You're Not Seeing It

AI-generated code isn't always obvious copy-paste jobs. It's a sophisticated mimic, leaving subtle fingerprints in style, logic, and structure. Here are the seven nuanced patterns that reveal a student didn't write the code they submitted, and what to do about it.

The Hidden Pattern That Catches AI-Generated Code

AI-generated code often passes traditional plagiarism checks because it's unique. The real giveaway isn't similarity—it's a strange, inhuman consistency. We'll show you the specific syntactic and structural patterns that tools like Codequiry analyze to flag AI-written submissions, turning your suspicion into actionable evidence.

The Ghost in the Machine Was a Student Named Alex

Midway through the semester, Professor Anya Sharma noticed a strange pattern: identical, elegant bugs appearing in submissions from students who sat on opposite sides of the lecture hall. Her investigation, using tools that looked beyond raw similarity, revealed a new, distributed form of cheating that MOSS could never catch. This is the story of the "AI Proxy Ring."

Your AI Detection Tool Is Probably a Random Number Generator

The market is flooded with AI-generated code detectors that promise certainty but deliver statistical noise. We audited three popular tools against a controlled dataset of 500 student submissions and found their accuracy was no better than a coin flip. It's time to demand evidence, not marketing claims, before you fail a student.

Your AI Detection Tool Is Lying to You About False Positives

AI code detection reports a 95% match. Your gut says it's wrong. You're probably right. This guide shows you how to move beyond the confidence score and conduct a forensic code review that separates AI-generated patterns from legitimate student work. We'll walk through three real student submissions from UC Berkeley's CS 61A course and show you exactly what to look for.
