What it tracks
5-hour session
Live percentage of your current 5-hour ChatGPT window and the exact reset time. No more discovering the cap mid-task.
Weekly limit
Rolling weekly usage with the next reset window. Plan your week instead of guessing what you have left.
Toolbar rings
Concentric progress rings sit right in your toolbar and shift toward red as you approach the cap. At 90 percent the icon blinks, with alerts at 75, 90 and 100 percent (all off by default).
Activity heatmap
A GitHub-style hourly grid shows when you actually use ChatGPT across the week. Spot your patterns and plan around your limits.
