Codect: AI-Generated Code Detection

Overview

Codect is a free and open-source tool designed to detect whether a piece of code was written by an AI or a human. It supports multiple programming languages and provides detailed insights based on various code features such as entropy, comment ratio, AST complexity, and more.

Features

• Multi-Language Support: Detect AI-generated code across various programming languages.
• Entropy & Complexity Analysis: Uses token entropy and AST depth to determine AI-generated patterns.
• Comment Ratio Evaluation: Analyzes documentation habits in code.
• Function & Loop Detection: Evaluates structure complexity.
• Local & Web API Support: Can be run locally or accessed via Flask-based API.
• Fully Open Source: No paywalls, no restrictions—improve and contribute to the project!

Star History

Installation

To install Codect and run it locally, follow these steps:

# Clone the repository
git clone https://github.com/GustyCube/Codect.git
cd Codect

# Install dependencies
pip install -r requirements.txt

# Run the Flask API
python main.py

Usage

API Endpoints

Codect provides two main API endpoints:

Basic Detection Endpoint (/basic)

• Input: JSON object with code key.
• Output: { "result": 1 } for AI-generated code, { "result": 0 } for human-written code.

Example:

curl -X POST "http://localhost:5000/basic" -H "Content-Type: application/json" -d '{"code": "def add(x, y): return x + y"}'

Premium Analysis Endpoint (/premium)

• Input: JSON object with code key.
• Output: JSON with detailed feature extraction and classification result.

Example:

curl -X POST "http://localhost:5000/premium" -H "Content-Type: application/json" -d '{"code": "def add(x, y): return x + y"}'

How It Works

1. The code is tokenized, and entropy is measured.
2. Comment ratio is calculated to analyze documentation habits.
3. AST parsing extracts function, loop, and exception counts.
4. The system assigns a score based on heuristic rules.
5. If the score exceeds a threshold, the code is flagged as AI-generated.
