What is FuelGauge
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.
