See your AI limits coming.

WhatsMyUsage is a menu-bar app for your Mac. It shows what's left of Claude, Codex, Cursor, Grok Build and 65 more agents, learns your pace, and warns you before a limit runs out.

Pay once. No account. 14-day refund. macOS 14 or later.

It speaks up before you run out.

Limits tend to run out mid-task, and some tools quietly switch to paid extra usage when they do. WhatsMyUsage watches your pace and tells you three things, in time to act.

Alerts show up here as the afternoon plays out.

Heads-up before it runs out

Timed from your pace, not fixed 80% or 90% marks. Choose 15, 30 or 60 minutes of notice.

Paid usage started

Know the moment a limit is hit and extra balance starts paying for it.

Limit is back

Hear when a capped limit resets, so you can pick the task back up.

Quiet hours pause alerts overnight, 22:00 to 08:00.

Every screen, before you buy.

There's no trial, so the app is here instead. Every panel below works the way it does on your Mac.

History is kept on this Mac for 30 days.

Free trackers show a number. WhatsMyUsage tells you what to do with it.

A percentage is free. What costs you is the limit that hits halfway through a refactor, or the extra usage that quietly starts billing. WhatsMyUsage is built for those two moments.

Warnings, not math homework

“38% left, resets in 2h” still leaves the math to you. WhatsMyUsage works out when you'll run out and warns you 15, 30 or 60 minutes before it happens.

It notices when you start paying

Hit a limit with extra usage on and the meter keeps running, in dollars. You hear about it the moment it switches, not on next month's invoice.

Opinionated, so you don't have to be

No data-source pickers, no wall of toggles. Four tabs of settings with defaults that are already right, in an app that feels like it shipped with your Mac.

Maintained like a product

Vendors change their usage APIs without warning. Here, fixing that is the job, not a weekend favor. Support is an email to the developer, and direct purchases come with a 14-day refund.

It pays for itself the first time it saves you a lockout or an overage.

Your usage stays on your Mac.

WhatsMyUsage reads the logins your AI tools already keep, asks each vendor for your usage, and stores the history in one file. There's no WhatsMyUsage account and no WhatsMyUsage server.
