## Description

Never hit an AI limit by surprise again. ⚡ UsageMeter is a real-time usage and limit tracker for Claude, ChatGPT and Grok: live meters for your 5-hour sessions, daily and weekly windows, reset countdowns, and alerts before you hit the cap — right in your toolbar.

✨ BUILT FOR FABLE 5
Fable 5 changed how fast weekly limits burn. UsageMeter shows your Fable 5 weekly usage as a live gauge with the exact reset time, so you can plan heavy sessions instead of discovering the wall mid-task.
