Every limit that matters, always visible. Know exactly where you stand before you hit a wall.

5-Hour Session Limit

See exactly where you stand in your current 5-hour window, with a live countdown to reset. No more surprise cutoffs mid-conversation.

7-Day Weekly Usage

Monitor your cumulative usage across all models. Plan your week, stay ahead of limits, and know how much runway you have left.

Claude Design Tracking

Subscription plan badge

Your plan is detected automatically and shown right in the popup header — Pro, Max 5x, Max 20x, or Team — so every limit you see matches your subscription.

Per-model weekly caps

Separate weekly limits for Opus, Sonnet, and Claude Design, each with its own bar — so you can see which model is burning your weekly quota. Shown on paid plans, starting at 0%.

Paid plans
Customizable Models menu

Show or hide any model from the Models menu, with Select all / Deselect all. Your choice is saved, so the popup shows only the caps you care about.
