FuelGauge — Claude AI Usage Tracker

About

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
