Desktop widget · Open source
One small desktop widget for the usage limits of your AI services. It also picks up Codex and Claude reset announcements: a heads-up when a reset is announced ahead of time, and a place to look when your usage suddenly drops to zero.
v1.0.0 · Windows · macOS beta · Linux beta
The problem
Every AI service keeps its limits in its own corner.
The fix
Claude, Codex, Antigravity, OpenCode Go, GitHub Copilot, and OpenRouter, side by side, each with its own usage bar. Active limits also show the time left next to the bar.
The problem
Then your usage drops to zero, and you do not know why.
The fix
Turn on reset announcements and AI Usage Clock picks up Codex and Claude reset announcements. Some are announced ahead of time, so you can get ready. Others come out of nowhere: the tile keeps the latest announcement in view, with one click to the original post.
The problem
Not every desk has room for another window.
The fix
Compact mode shrinks the widget to one pill per service.
Optionally get a notification when a new announcement shows up (native notifications on Windows), with a separate switch for each type. Reset announcements and their notifications are off by default.
There is no AI Usage Clock account, server, or telemetry. API keys are kept in your operating system's secure storage.

Reset announcements
AI Usage Clock picks up reset announcements, so you get a heads-up when one is announced ahead of time, and can see what happened when it was not.
Ahead of time
That is your heads-up to get ready. This type comes from Codex. Beside it sits a Watch row, an AI forecast of how likely a reset is. It is not an announcement, and it never sends a notification.
When it happens
The tile shows the latest event and how long ago it happened. Banked is a related type: you were granted a reset credit that you can redeem yourself. Claude shows Reset and Banked.
Later, when usage reads zero
When your usage suddenly drops to zero, open the tile to check whether a reset just happened. The latest announcement stays in view, with one click to the original post.
Optional, and off by default. Announcements come from two independent third-party trackers, codex-resets.com and claude-resets.com, and can be late or wrong, so check the original post. Notifications are optional too, with a separate switch for each type.
FAQ
They are off by default. Turn them on under Settings → General with Codex Resets or Claude Resets. AI Usage Clock then reads codex-resets.com and claude-resets.com, asking each at most once every 15 minutes while the app runs.
The tile shows the latest event and how long ago it happened, labeled Announced (Codex), Reset, or Banked. The data is compiled by third parties and can be late or wrong, so treat the original post as the source of truth.
Your settings, usage history, and sign-in sessions stay on your computer. Sessions and API keys are stored with your operating system's credential facilities. There is no telemetry and no AI Usage Clock server.
The app connects directly to the services you turn on. If you enable reset announcements, it also contacts codex-resets.com and claude-resets.com; those sites see your IP address and the app's name and version. More in SECURITY.md.

The macOS (a menu-bar item instead of a floating widget) and Linux builds are published, but refreshing real accounts has been verified on Windows 11 alone, so treat them as early-stage.
