Live AI usage
Private, and Studio Grid never sees it
More than a number in the menu bar.
Studio Gauge reads your Mac and your AI tools from one place, the menu bar, so you always know what's running and how much you've got left.
Battery & health

Storage pressure
Free space and disk pressure without opening About This Mac. A quiet nudge before you run out.

Studio Gauge holds your MacBook at the level you choose, overnight and even when the app is closed, then tops up to 100% once for a travel day.
Live AI usage
Flip the panel for real-time Claude, Codex, Gemini and Cursor usage, including requests, tokens, and how close you are to your limit.

Private by design
Studio Grid never sees your usage.
Gauge reads the usage data your AI tools already keep locally and, if you log in, from each provider’s own API. Your usage is never uploaded to Studio Grid, and there's no telemetry or cloud dashboard involved.
Reads local logs only, using the same session files your CLIs already write.
No account or sign-in needed. Activate once with a free key and you’re set.

claude login, estimates from local logs without it.

GOOD TO KNOW
Questions answered.
Quick answers about what Studio Gauge tracks, what it never touches, and what it costs (nothing).
Still have a question?
Send us a note and we will come back to you, usually the same day.
Which tools does it track?
Claude Code, Codex CLI, Gemini CLI and Cursor today. It shows only the ones you actually use, so a Claude-only setup will not show empty rings.
Do I need a Claude login?
No. With a Claude login token it pulls exact numbers from Anthropic’s API, and without one it estimates from your local session logs against budgets you can calibrate.
Is it really free?
Yes. Gauge is the free front door to the Studio Grid suite. You activate it once with a free key so we can count installs.
What macOS do I need?
A native, notarized menu bar app on Apple silicon or Intel, shipped as a universal build of a few megabytes.
Does it read my prompts or send my data anywhere?
No. Gauge only takes token counts, times and project folder names from the usage files your AI tools already keep on your Mac, and your prompts are never stored. There is no analytics or tracking. It goes online only to refresh usage from the tools you are signed in to and to check for updates.
Free playbook
Steal my Chrome extension launch playbook
The real playbook I used to ship Studio Colour, covering permissions, CSP, a listing that won’t trip keyword-spam filters, privacy, the OAuth gotcha, and how I won a rejection appeal. It also includes a working MV3 starter you can load in 60 seconds. It's free and arrives straight in your inbox.
