ClaudeCap — Usage Forecaster

See exactly when you'll hit your Claude usage cap — before it blocks you. Live 5-hour and weekly forecasts.

Claude blocks you with zero warning. It checks 8 separate internal usage buckets and never tells you which one just tripped — you just hit a wall mid-task. ClaudeCap fixes that. It reads Claude's own usage data live, right in your browser, and shows you both your 5-hour and weekly caps as they move — no guessing, no rounded numbers hours late. HOW IT WORKS Install the extension and open claude.ai. ClaudeCap starts tracking automatically the moment you send a message — no setup, no account, no API key required. FREE PLAN - Live 5-hour and weekly usage bars - Exact reset times for both windows - Toolbar badge showing your current % PRO PLAN ($3.99/mo) - Pace forecast — "at this rate, you'll hit the cap in ~35 min," calculated from your actual usage trend, not a static percentage - Proactive desktop notifications at 80% and 95% of both caps, so you can wrap up before you're cut off - Never get blindsided mid-conversation again Built for Claude Pro and Max users who run long coding sessions, research threads, or agent workflows and are tired of hitting the wall with no notice. 100% local — ClaudeCap only talks to claude.ai's own usage endpoint. Nothing is sent to any third-party server.
