Local-first AI capacity for Windows
Know what you have left before it stops you.
Ceiling keeps remaining capacity, reset times, alerts, and usage history close to the Windows taskbar—across the AI plans you actually use.
Free and open source · Windows 10 / 11 · Signed builds
More than a reset timer
See the capacity you use over time.
Compare providers, understand the rolling window you are in, and keep a local record of activity instead of guessing why a limit changed.
Usage history
Capacity is clearer with context.
Ceiling turns a changing percentage into a useful history: how much was used, which window is active, and what changed since the previous check.
- Compare provider usage on the same clock.
- Review local activity without exporting it to a third-party dashboard.
- Keep reset times next to the usage that explains them.
Always nearby
Useful when you are working, quiet when you are not.
The capacity strip sits above the taskbar without stealing focus. Hover for a fuller view, open the tray flyout when you need detail, and stay out of a dashboard the rest of the time.
One quiet view for the plans you use.
Ceiling currently supports the AI subscriptions and sessions that are hardest to keep track of during a working day.
Local means local
Ceiling does not run a server for your usage data.
It reads usage from sources on your PC or each provider’s own usage endpoint. Credentials, cookies, API keys, and browser imports are opt-in and remain on your machine.
