Y Combinator: Paxel, understand how you build with AI

20 hours ago

Paxel is a tool by YC that analyzes AI coding session transcripts from Claude, Codex, and Cursor to help developers understand their own coding habits and compare with others.
It processes over 611,000 uploaded sessions locally via Docker, ensuring code privacy, and provides a builder profile across dimensions like steering, execution, and planning.
Users can upload sessions from all repositories or a single one using specific commands, and receive insights such as archetypes (e.g., Architect), decision patterns, and growth suggestions.
The tool is free, takes 15-30 minutes, and aggregates data across multiple machines when using the same email, with options to link results to Startup School applications.
