Track your Claude.ai usage in real time. See session and weekly limits, reset times, and color-coded progress — in your toolbar. Track your Claude.ai usage in real time. See session and weekly limits, reset times, and color-coded progress — in your toolbar. The only Claude usage tracker that monitors Claude Design and Opus weekly limits alongside your 5-hour session and 7-day weekly limits — plus paid extra credits — all in your browser toolbar. Stop opening claude.ai/settings/usage. A color-coded badge tells you at a glance whether you can keep working or need to pace yourself, with countdowns to every reset. No account, no API key, no data leaves your browser. Reads your existing Claude session the same way the official settings page does. WHAT YOU SEE - Session usage (5-hour rolling window) with reset countdown - Weekly usage (all models combined) with reset day/time - Sonnet weekly usage (when your plan includes a Sonnet sub-cap) - Opus weekly usage (when your plan includes an Opus sub-cap) - Claude Design usage (when your plan includes it — most trackers ignore this) - Paid extra credits used vs. monthly cap (when enabled on your plan) - Inline banner when your claude.ai session expires — last-known data stays visible - Toolbar badge: green under 50%, yellow 50 to 80%, red above 80% - Configurable auto-refresh: 1, 2, 5, 10, or 60 minutes WHO IS THIS FOR Claude Pro, Max, and Team users who hit limits and want to plan their work. Especially useful for Claude Code users on Max plans and teams using Claude Design.
