AI Usage Bars — for Claude.ai

Toolbar usage bars for your Claude.ai session and weekly limits. Unofficial, your data never leaves the browser.

Two bars on your toolbar icon show how much of your Claude.ai limits you've used — without opening the settings page every five minutes. ▸ What you see on the icon • Top bar: your 5-hour session usage • Bottom bar: your 7-day rolling weekly usage • Colors shift from green to amber to red as you approach the limit ▸ What's in the popup • Exact percentages for both windows • Time remaining until each reset • Settings shortcut and useful links ▸ Privacy-first: 100% local Your usage data is read directly from claude.ai using your own browser session, cached locally in chrome.storage, and never sent anywhere else. No backend, no analytics, no telemetry. The extension cannot read or store your cookies. Auditable source code on GitHub. ▸ 11 languages with auto-detection English, Spanish, Portuguese (Brazil), French, German, Italian, Russian, Japanese, Simplified Chinese, Hindi, and Arabic (RTL). The interface follows your browser's language automatically. ▸ How it works The extension uses the same internal endpoint that claude.ai/settings/usage consumes, authenticated by your existing session cookie. It refreshes at a configurable interval (1, 5, or 15 minutes). If you sign out of claude.ai, the icon switches to a "signed out" state until you sign back in. ▸ Requirements You must be signed in to claude.ai in the same browser. Works for both individual accounts and organization accounts — it auto-detects your active org. ▸ Open source — MIT licensed Source code, releases, translations and issue tracking: https://github.com/brassoy/ai-usage-bars ▸ Disclaimer This is an UNOFFICIAL extension not affiliated with, sponsored by, or endorsed by Anthropic. Claude is a trademark of Anthropic, PBC. If Anthropic changes their internal endpoints, the extension will need to be updated.
