简介
See your Claude limit before you hit it. ⚡ UsageMeter shows every Claude usage limit live, right under the claude.ai message box and on your toolbar icon. It tells you when you'll be blocked at your current pace, and what each reply cost your session.
⏱ SEE THE WALL COMING
✅ 5-hour session, weekly and per-model limits (Opus, Fable…) as live gauges, straight from your account
✅ "At this pace: blocked around 9:40 PM": a forecast from your last 45 minutes (12 hours for the week)
✅ Reset countdowns for every window, and today's budget: what's left of your week, spread until the reset
✅ Works with Claude Free, Pro, Max and Team accounts
💬 THE PRICE OF EVERY REPLY
✅ Under each reply on claude.ai: what it took from your session, for example "+1.8%"
✅ Click the price to see what the reply weighs: the conversation read again, your message and the reply
✅ When Claude Code or another chat moved the limit at the same time, you see "≈" or nothing, never a wrong number
✅ An attachment's weight before you send it, computed on your device
✅ Claude down or overloaded? A pill tells you it's not your limit
📊 IS IT ME, OR CLAUDE?
✅ What your subscription got you this month at API prices, next to what you pay, with a card to share
✅ A public radar of the days when more UsageMeter users than usual hit a limit
🔔 ALERTS BEFORE THE WALL
✅ "Remind me at…" when you're blocked: a notification at the reset that reopens your chat. The first one is free
✅ With Pro: notifications at your threshold, when your pace would block you soon, at 100% and the moment a limit is back
✅ Never twice: across your browsers and the desktop app, only one device rings
✅ With Pro: 90 days of history and the chats that weighed most on your week. 7-day free trial
💻 CLAUDE CODE TOO
See this week by product (Claude Code, chats, Cowork). With the free UsageMeter Link app for Windows, your Claude Code tokens are added up across all your PCs.
🚀 HOW IT WORKS
1. Install UsageMeter: no account needed, no API key
2. Open claude.ai and keep working as usual
3. Your gauges fill in live. Click the icon for the full breakdown.
🔒 YOUR DATA: WHAT IS COLLECTED, AND WHERE IT GOES
To count tokens, UsageMeter reads the open conversation in your browser. That text is counted on your device, then discarded: it is never stored and never sent to our servers. Your Claude session cookie stays on your device. Without an account, only technical data reaches us: a random install ID, the version number, your IP address as with any web request, and anonymous counters. If you sign in, your usage figures, token counts, reset times, Claude account labels (email, name, plan) and settings sync to our servers in the EU, so the web dashboard, the desktop app and your other devices stay in step. Your data is never sold or used for advertising. Signing in is optional, and signing out stops the sync. Collection, use, storage and sharing in detail: https://usagemeter.app/privacy
🎨 MAKE IT YOURS
Side panel and a two-ring toolbar icon (Alt+Shift+U), 50+ themes, several accounts, usage history, Claude widgets for your GitHub README, 34 languages.
