Claude Limit Guard

Claude Limit Guard shows your real-time usage right inside the Claude.ai interface — no digging through settings, no guessing when you'll hit a wall.

WHAT IT SHOWS
- Session usage — your 5-hour rolling window utilisation (%)
- Weekly usage — your 7-day rolling window utilisation (%)
- Live countdown — exactly how long until each window resets
- Colour-coded bars — turn yellow near 80%, red near 98% so you always know where you stand

HOW IT WORKS
A slim usage bar appears just below the model selector on every Claude chat page. It reads usage data directly from Claude's own API (the same data your account already uses) and refreshes automatically every hour, or whenever you switch back to the tab. Click the bar at any time to force an instant refresh.

OPEN & TRANSPARENT
The tooltip on the bar explains exactly where the data comes from: "Usage data is read from the same-site usage API for your logged-in account only. Nothing is sent to third-party servers."
