Usage Meter for Claude

See your Claude 5-hour and weekly usage limits at a glance, with reset times. Unofficial; not affiliated with Anthropic.

A tiny, calm meter for your Claude subscription limits. Claude plans come with a 5-hour session limit and a weekly limit, but checking them means digging into claude.ai settings. This extension puts them where you can always see them: • Toolbar badge — your current 5-hour usage %, color-coded (green → amber → red as you approach the limit) • Click the icon — both the 5-hour and weekly bars, with exactly when each limit resets ("resets in 2h 15m (9:30 PM)") • 24-hour history — a mini bar chart of your session usage over the last day, so you can see when you actually burn through it • Pacing Score — a weekly 0–100 estimate of how smoothly you're allocating your plan: steady pace, no burnouts, landing near (not at) the limit. With badges, a streak, and a full dashboard: score trend, component breakdown, 7/30/90-day history, and JSON export. All computed locally; estimates based on observed usage patterns. • Auto-refreshes every 10 minutes (configurable 1–15 min) • Available in English and Japanese — follows your browser language PRIVATE BY DESIGN The extension talks only to claude.ai, using the login session you already have in your browser. There is no separate login, no API key, no account, no analytics, and no server of ours — nothing about your usage ever leaves your machine. HOW IT WORKS It reads the same usage data the claude.ai web app itself displays. You just need to be signed in to claude.ai in this browser. If you're signed out, the badge shows "–" and the popup links you to sign in. NOTE This is an unofficial tool and is not affiliated with, endorsed by, or sponsored by Anthropic. It reads an undocumented claude.ai endpoint, which Anthropic may change at any time; if that happens the extension shows a diagnostics view instead of numbers until it's updated.
