AI Commit Tracker

Automatically detects AI-generated code from any AI tool and tags every git commit with the real AI usage percentage — no configuration needed.

Features

Universal detection — works with Copilot, Cursor, Claude Code, Tabnine, Codeium, Windsurf, ChatGPT paste, and any other AI tool
Real-time status bar — live [AI X%] indicator updates as you code
Auto-tags commits — appends [AI X%] to every commit message automatically via a git hook
Git metadata storage — saves full AI stats (lines, files, session) as git notes on each commit
Per-file breakdown — see exactly which files had AI involvement and how much
No API keys required — pure heuristic detection, works offline

The extension uses heuristic signal analysis to detect AI-generated code:

Multi-line insertions happening faster than human typing speed
Long single-line completions characteristic of AI suggestions
Syntactically complete blocks (balanced brackets, function bodies)
Consistent indentation patterns typical of AI output
File system watcher for AI tools that write directly to disk (Claude Code, Cursor, etc.)

Install the extension and start coding. You will see:

Status bar: [AI 73%] — live AI percentage for the current session
