Ceiling

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.

More than a reset timer

See the capacity you use over time.

Find out how many tokens you have burned since your last reset, compare Codex and Claude on the same clock, and keep the whole record on your PC.

Compare

Codex and Claude, on one clock.

The two providers reset on different schedules, so Ceiling lines them up on rolling windows that end right now. That is the only way the comparison is fair.

  • See which assistant is doing more work, over the last five hours and the last seven days.
  • Reset-aligned figures stay in each provider's own view, where they belong.
  • Read it without exporting anything to a third-party dashboard.

Since your last reset

Know what this window has cost you.

Every provider window shows the tokens processed since it reset, with an estimated API value beside them. That figure is an API-equivalent estimate from your local logs, not a subscription bill.

  • Tokens and estimated value since your 5-hour and weekly resets.
  • Plus a 30-day breakdown by model, reasoning effort, and project.
  • Models with no public price stay excluded rather than reading as $0.00.

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.

Optional alerts can flag a limit approaching, an unexpected reset, restored capacity, or a banked reset.

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.
