at a glance.

Claude and Codex. Usage percentages and time until reset, in one beautiful gauge.

Unofficial, unaffiliated with Anthropic or OpenAI · numbers and promo shown are examples

One gauge. Two workspaces.

Claude and Codex.
No more tab-hopping.

Both limit windows, organized on one screen. You don't need to stop working just to check "how much do I have left?"

Make it yours.

Five looks. Pick yours.

Side panel or widget, switch with one tap. Terminal for devs, Sorbet if you like it soft. Pick whatever fits your mood.

Numbers shown are examples. You can switch appearances anytime.

Always beside you.

Beside your work,
whenever you need it.

Check it in Chrome's side panel. Working in a terminal? Keep it open as a small independent window.

Quietly automatic.

You don't have to think
about it. It's always fresh.

Auto-refreshes while it's open. Time until reset counts down quietly in the background.

Frequently asked questions

Is AIGauge free?
Yes. AIGauge is a free Chrome extension. No AIGauge account is required. To read usage, you need a tab logged into the target service.
Which services does it support?
It supports Claude subscription limits on claude.ai and Codex usage limits on chatgpt.com. API-key metered billing and dollar totals aren't covered.
Is usage data sent anywhere?
Usage data is never sent to AIGauge's servers and is stored on-device in Chrome. Reading it uses your already-logged-in claude.ai or chatgpt.com tab.
What does the promotional slot communicate and count?
It fetches a public JSON file without credentials to switch what's shown. If a remote image is displayed, your IP address and similar info may reach the image host, as with any normal web image. Clicking a promotion counts the app name, slot, and daily click count without identifying you personally. Claude/Codex usage and account information are never included.
Is this an official extension?
No. AIGauge is an unofficial tool from Ray of Ray and is not affiliated with Anthropic or OpenAI. Internal API changes at either service may temporarily break the ability to fetch usage.

Spend less time worrying
about limits.
