Andon; AI Limit Watcher

Andon; AI Limit Watcher

In development / beta ・ macOS menu-bar app (Windows planned)

Are you actually using up your AI subscription? Keep constant track of what's left — and when it resets — across Claude, ChatGPT (Codex), and GitHub Copilot. Stop wasting quota you already paid for, and never hit the wall unaware.

Why it helps

Subscription quota expires if you don't use it.

Claude, ChatGPT and Copilot are flat monthly plans — but under the hood they're per-window quotas (every 5 hours, every week). Let a window reset unused and you've wasted what you paid for. Hit the ceiling unaware and your work stops cold. This watcher keeps you clear of both.
