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.
Features
Toolbar badge
Your current 5-hour usage %, color-coded — green to amber to red as you approach the limit.
Both bars, with reset times
Click the icon for 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. All computed locally.
Per-model weekly caps
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-refresh
Refreshes every 10 minutes by default, configurable from 1 to 15 minutes.
Sync across your devices
Optional, off by default. Use two computers and your history merges instead of splitting in two. It rides on Chrome's own profile sync — no account to create, no server of ours involved.
Five languages
English, 日本語, Français, Español and Deutsch. The UI follows your browser language, with a manual override in settings.
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.
Read the full privacy policyHow 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.
Unofficial. Not affiliated with, endorsed by, or sponsored by Anthropic. “Claude” is a trademark of Anthropic, PBC. The extension reads an undocumented claude.ai endpoint, which Anthropic may change at any time; if that happens it shows a diagnostics view instead of numbers until it's updated.
