Watcher by EXE
Your AI coding spend,
in view.
The owl watching your tokens, models and projects. Bring the usage saved by your local coding tools together, with API-equivalent costs you can understand.
Download for Mac
Know what the tokens mean.
See models including GLM and Kimi wherever a supported client records them. Available API rates account for input, output and separately recorded cache tokens.
Today, and the bigger picture.
Explore daily and historical summaries by model, project and tool. Cached history is reused across periods, with fresh daily usage added as it arrives.
Download. Drag. Open.
Open the disk image, drag Watcher by EXE into Applications, then open it. Click the yellow owl in your menu bar. The app includes its runtime and command-line tool.
Costs are API-equivalent estimates using the latest available rates. Coverage depends on retained local logs: Copilot currently records output tokens only, Cursor Auto uses estimates, and unknown model prices are flagged. Python Kimi CLI and older OpenCode JSON storage are not yet supported.
