Usage tracker

A deliberately simple v1: log each session as light, medium or heavy through the current window and watch the bar. It will not match Anthropic’s internal accounting exactly, but it tells you the thing that matters — whether you are on pace to be cut off.

Entries live in this browser tab only and are not saved anywhere.

9 of 200 units used across 2 sessions. Heavy sessions account for 89% of it.

How to use the number

If heavy sessions dominate the bar, the problem is context volume, not frequency — you are paying for the same files repeatedly. Start with how the limits actually work, then the playbook.

If light sessions dominate and you still hit the cap, the issue is usually a single never-ending thread quietly carrying its whole history into every new question.
