How much AI fuel is left? Track your LLM usage limits — budget pace, cooldown timers, depletion alerts. Paying for Claude Pro but flying blind on your usage?
FuelGauge puts a fuel gauge in your browser toolbar. One glance tells you how much AI budget you have left — and whether you're burning too fast or wasting what you paid for.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
WHY FUELGAUGE?
You pay $20/month for Claude. You get a vague "usage limit" with zero visibility. Then mid-session, mid-thought — you're cut off.
Or worse: the month ends and you realize you only used 40% of what you paid for. That's $12 wasted.
FuelGauge fixes both problems.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
HOW IT WORKS
FuelGauge reads your usage data from Claude's settings page (the same data you'd see manually). It stores everything locally in your browser — no data leaves your machine unless you opt into Cloud Sync.
▸ No account required ▸ No external server ▸ No tracking, no analytics on your usage ▸ Open data: your usage data stays on your device
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
WHO IS THIS FOR?
▸ Developers who live in Claude Code and can't afford to be cut off mid-task ▸ Writers, consultants, researchers who use Claude daily for work ▸ Anyone paying $20+/month and wanting to get full value from their subscription
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
PERMISSIONS EXPLAINED
▸ Storage — Save your usage history locally ▸ Alarms — Schedule periodic usage checks ▸ Cookies — Authenticate with claude.ai (read-only, to fetch your usage) ▸ Notifications — Alert you when thresholds are reached
FuelGauge only connects to claude.ai. It cannot read any other website.
