Usage Meter for Claude

A tiny, calm meter for your Claude subscription limits. WHAT'S NEW IN 1.5.3 • The Pacing Score is now daily, and appears after just two active days. It used to need a reading at the exact moment your weekly limit reset — if your browser was closed then (overnight, for many time zones), the score never appeared at all • The streak flame counts good days now, not weeks. Days you don't use Claude pause it instead of breaking it • When the score can't show yet, the popup says what it's actually waiting for, instead of "after your first full week" • The history chart now labels its axes — % on the left, dates along the bottom — and no longer draws extra-usage spend or untouched 0% caps as if they were usage WHAT'S NEW IN 1.5.2 • Now in French, Spanish and German as well as English and Japanese — the whole extension, not just this page. It follows your browser, or you can pick a language in the dashboard settings • There's finally somewhere to tell us something is broken, or ask for something: a feedback link at the bottom of the dashboard 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 daily 0–100 estimate of how smoothly you're allocating your plan: each day's burn rate against what the remaining weekly budget can sustain, averaged over the last 7 days. With badges, a daily 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. • Per-model weekly caps get their own bar — when a specific model (for example Fable) carries its own weekly limit, you see it alongside the all-models figure. That cap can fill up first, so it's often the number that actually stops you • Auto-refreshes every 10 minutes (configurable 1–15 min) • Sync across your devices (optional, off by default) — use two computers and your history merges instead of splitting in two. Chrome only: it rides on Chrome's own profile sync, so there's no account to create and no server of ours involved. On other browsers, use export/import instead • Available in English, Japanese, French, Spanish and German — follows your browser language, with a manual override in the dashboard • A feedback link in the dashboard, for when something breaks or you want something it doesn't do yet 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 is ever sent to us. Device sync is off unless you switch it on, and when you do, it's your own browser doing the syncing. 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.
