AI Usage Bars — for Claude.ai

About

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
