AI Usage: my Claude and Codex limits in the menu bar

AI Usage sits in the macOS menu bar and shows one number per provider: how much of the Claude and Codex quota is used. Click it, and you get the details.

What it shows

• The quota windows. The 5-hour and the weekly limit for each provider, plus extra model-specific limits where a plan reports them.
• How fast I’m using it. A small burn history for the current window, so I can see whether a session was calm or intense.
• When it resets. A countdown, and if I want, an estimate like “about 2 hours left at this pace”.
• History. A simple chart over 1, 7 or 30 days, stored locally on my Mac.

Built to stay local

I think a tool like this should be boring in the best way. It runs locally, keeps its history in a folder on my machine and never touches the login Claude Code itself uses. For multiple Claude accounts there’s a guided setup that keeps each one separate.

There’s no signed download. It’s a personal project, so you build it yourself with one command. Honestly, I like that. It keeps it small and honest.

Why it’s in the Lab

It’s a good example of how I use AI tools now: not just for client work, but to build the small things I wish existed. This one started as a quick fix and turned into something I look at fifty times a day.
