Mac menu-bar app
Whir
See the estimated API-equivalent value of your Claude Code and Codex usage, on your Mac.

Your AI usage at a glance
Whir uses local Claude Code and Codex usage logs to estimate their API-equivalent value and displays it in your Mac menu bar.
What you can see
- Today’s usage and hourly, daily, weekly, and monthly history
- Breakdowns by provider, model, and project
- A comparison of subscription cost and estimated usage value
- CPU, memory, and disk activity, plus CSV export
The amount is estimated usage value at API prices, not your actual bill or remaining subscription allowance.
Data handling
Calculation happens on your Mac, with an optional network request to refresh model prices. Refer to the privacy information supplied with your app for version-specific details.

Whir is available as a free download on the Mac App Store. Requires macOS 14 or later.
