AI usage. One elegant view. — ceiling.win
Ceiling is a focused, local-first Windows companion for the AI subscriptions you actually use. It keeps rolling limits, reset times, and stale/error states visible from the system tray or a lightweight capacity strip above the taskbar.
The goal is not another giant provider dashboard. It is a fast, calm way to answer one question: how much AI capacity do I have left, and when does it reset?
- OpenAI Codex
- Claude
- Cursor
- Gemini / Google AI
- GitHub Copilot
Additional providers remain available from the underlying foundation while Ceiling is narrowed around reliable support for the core five.
- Taskbar-adjacent capacity strip: Windows 11 does not support old-style third-party taskbar toolbars, so Ceiling uses a transparent, always-on-top strip that sits just above the taskbar without stealing focus.
- Tray at a glance: a compact flyout with each provider's remaining capacity, reset time, source, and freshness.
- Truthful state: a visible distinction between live, cached, stale, and failed reads. No fake precision when a provider cannot report a limit cleanly.
- Local first: credentials and usage data stay on the machine. Browser cookies, API keys, and login sources remain opt-in.
- Windows-native: Tauri, React, and Rust; fast startup, low idle work, and system accent-aware appearance.
Ceiling runs on Windows 10 and 11.

The installer and portable build are code-signed. Ceiling is local-first: it reads usage from sources on your PC or from each provider's own usage endpoint, and never sends your credentials or usage data to Ceiling-operated servers. See How Ceiling gets your data for the per-provider detail.
