Quota Monitor for Claude

See your Claude subscription usage — current session and weekly limits with live reset countdowns.

⚠ This extension is being retired. It will be removed from the Chrome Web Store on 31 October 2026 and will stop receiving updates. Existing installs keep working until Anthropic changes something on their side, which will not be fixed here! SWITCH NOW to AI Quota Monitor, its replacement — the same features plus ten more providers, a side panel and usage history: https://chromewebstore.google.com/detail/oebcijilhgehohceghmcafhcmnbajakk - - - Quota Monitor for Claude shows the same usage data as the claude.ai usage page — right in your toolbar: • Current session (5-hour window), weekly all-models, and per-model weekly limits • Live countdown to each reset, plus the exact local reset time • Toolbar badge with your highest usage percentage — session or weekly, whichever is closer to its limit — refreshed every 5 minutes • One-time notification when any limit crosses 90% — once per reset window, no nagging • Shows your plan (Free, Pro, Max) and supports accounts with multiple organizations • Optional fallback: paste a Claude Code OAuth token to monitor usage without a claude.ai session Zero setup: if you're signed in to claude.ai in this browser, it just works. No account creation, no analytics, no external libraries. Your data stays yours: the extension talks only to claude.ai and api.anthropic.com, stores its cache locally in your browser, and sends nothing anywhere else. This extension is an independent project and is not affiliated with, endorsed by, or sponsored by Anthropic. "Claude" is a trademark of Anthropic, PBC. - - - New in 1.0.5 • Retirement notice now states the Web Store removal date (31 October 2026) and that updates stop. In the final week before removal it can no longer be snoozed. No other changes. New in 1.0.4 • This extension has moved to AI Quota Monitor (link above). The popup now shows a notice with an Install button; "Later" hides it for 14 days. Everything else works as before. New in 1.0.3 • Toolbar badge now shows whichever of your session or weekly limit is higher — so a used-up weekly quota no longer hides behind a fresh 5-hour window showing 0%. A "W" prefix (e.g. W85) tells you the weekly limit is the one on the badge. • New setting under Toolbar badge: switch back to "Current session only" if you prefer the previous behaviour. New in 1.0.2 • Fixed: Plan label (Pro / Max / Max 5x) now updates immediately when you upgrade or downgrade your subscription. Previously the label could stay stale until the extension was reinstalled or the organization was switched.
