Gauge — AI Usage Meter

Live usage meter for Claude, ChatGPT, Gemini & Grok. Token breakdown, predictive alerts, cross-platform handoff.

Gauge is the smartest usage meter for AI power users. WHAT IT DOES Claude, ChatGPT, Gemini, and Grok all have message limits — but none of them tell you clearly how many messages you have left, when you'll run out, or what's eating your context. Gauge fixes all of that in real time. LIVE INLINE METER A thin bar appears beneath Claude's input box showing your exact usage percentage, estimated messages remaining, and a live reset countdown. Model-aware — Opus burns 5× faster than Sonnet. MULTI-PLATFORM DASHBOARD One popup shows Claude, ChatGPT, Gemini, and Grok usage side by side. Switch tabs to see each platform. TOKEN BLOAT BREAKDOWN See exactly what's eating your context: uploaded files, chat history, project knowledge base, system prompts. Know what to trim before you hit the wall. CROSS-PLATFORM HANDOFF When you run out of Claude headroom, send your full conversation — including all code artifacts — to ChatGPT, Gemini, or Grok in one click. FREE FOREVER — POWERFUL BY DEFAULT The free tier beats most paid competitors on core metering. Pro adds intelligence on top: predictive alerts, 30-day usage history, unlimited handoffs, boost window tracker, and API cost tracking. PRIVACY FIRST All data stays in your browser. No servers. No accounts. No tracking. Usage is read from each platform's own API using your existing session — zero extra network requests.
