Open source

What is Poirot?

Poirot is a native macOS app for reviewing your Claude Code sessions after the fact. It reads the local files Claude Code already writes and presents them in a readable interface, so you can see which files were touched, how many tokens a session used and where it got stuck. Sessions are grouped by project with search, sort and agent filtering, and sub-agent runs sit under their parent with a Gantt-style timeline. Analytics cover daily activity, token trends, model distribution, per-model cost and 5-hour and 7-day rate-limit gauges. It also browses slash commands, skills, MCP servers, hooks, plans, TODOs, memory files, prompt history and debug logs. The project states there is no login, no tracking, no analytics, no bring-your-own-key setup and no extra cost, and that it works offline in under 6 MB. It is MIT licensed, needs macOS 15 or later, and installs with Homebrew.
