AI Fuel

Never run out of AI fuel mid-task. Track tokens, control budgets, and route prompts intelligently.

AI Fuel is a privacy-first control center for anyone who juggles multiple AI accounts and API keys. Instead of guessing how much quota you have left, AI Fuel shows it right in the toolbar popup. What you get: - A unified daily burn gauge across every provider you connect. - Per-provider quota meters with live reset countdowns for tokens and requests. - A Smart Router, powered by an on-device decision engine, that recommends which provider and model fits a task based on your remaining quota. - Desktop alerts before you hit a limit (warning at 30%, critical at 10%). - A 30-day view of your spend and token usage. Privacy by design: - API keys are encrypted with AES-GCM (Web Crypto) and stored only on your device. - The extension reads numeric rate-limit metadata; it never reads the content of your conversations. - The Smart Router runs locally (WebGPU with a WASM fallback). Prompts used for routing never leave your computer. - No account, no analytics, no server. Free to try for 3 days. Pro adds unlimited providers, the recommendation engine, desktop alerts and multi-browser sync.
