assaio turns the AI coding session logs already on your machine into honest engineering analytics: adoption, tokens, model mix, estimated cost, AI output, friction, and project-level effectiveness. It supports Claude Code, Codex CLI, Gemini CLI, GitHub Copilot CLI, and Cline. Fully offline by default - no account, no telemetry, prompts and code are never read. Open source, extensible, and self-hostable for teams.
