Gauge — AI Usage Meter

Live usage meter for Claude — track limits, predict when you'll run out, and hand off any chat to ChatGPT, Gemini or Grok.

Gauge is the smartest usage meter for Claude power users. Claude tells you almost nothing about how close you are to your limit — how many messages you have left, when your 5-hour and weekly windows reset, what's filling your context, or how fast you're burning through Opus. Gauge shows all of it, live, read straight from Claude's own usage data. LIVE CLAUDE METER A thin bar sits inside Claude's input box with your exact session usage, estimated messages remaining, and a live reset countdown. It's model-aware — Opus burns far faster than Sonnet, and Gauge accounts for it. A draggable mini-dashboard and a toolbar popup give you the full picture, including your plan (Pro / Max 5x / Max 20x). EXACT LIMITS, NOT GUESSES • 5-hour session % and weekly % from Claude's real utilization API • Per-model weekly limits (Opus and Sonnet shown separately on Max plans) • Context-window tokens used vs. your model's limit, with a prompt-cache timer • A toolbar badge you can set to show usage % or a countdown to reset USAGE CREDITS (NEW) If you've turned on Claude's usage credits, Gauge shows your real spend, monthly limit, and utilization — so credit usage never surprises you on your bill. PREDICTIVE BURN-RATE (NEW) Gauge measures your actual usage and forecasts when you'll hit the session limit and the weekly cap. It also learns your time-of-day pattern and tells you the best window to start heavy work. NEWEST MODELS, INCLUDING FABLE 5 (NEW) Opus 4.8/4.7/4.6, Sonnet 4.6, Haiku 4.5, and Fable 5 (with its "2× usage" cost and availability window reflected honestly). CONTEXT BREAKDOWN See what's filling your context window — chat history, attached files, system/project instructions — with a trim coach. ONE-CLICK CROSS-PLATFORM HANDOFF Out of Claude headroom?
