About FuelGauge — Claude AI Usage Tracker
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.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
WHAT YOU GET (FREE)
▸ Real-time gauge — See your remaining budget as a clear percentage, right in the toolbar icon
▸ Pace tracking — Are you ahead or behind your ideal daily pace? Delta shown in points
▸ Depletion prediction — "At this rate, you'll hit your limit Tuesday at 3pm"
▸ Smart advice — Actionable banner: on pace / under-used / slow down / critical
▸ Dynamic icon — Color-coded gauge on the toolbar icon with % badge. No need to open the popup
▸ Cooldown timer — Know exactly when your 5-hour session window resets
▸ Under-utilization alerts — FuelGauge is the only tool that tells you when you're WASTING your subscription
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
PRO — $9 ONCE, YOURS FOREVER
▸ 7-day & session charts — Visual history of your consumption patterns
▸ Push notifications — Get alerted via ntfy before you hit a threshold
▸ Session reset alerts — Know the instant your limit resets

No subscription. No recurring charge. Pay once, done.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
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
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
