About AI Calorie Tracker

Free, open-source nutrition counter powered by OpenAI. Track calories and macros effortlessly without accounts or server tracking.

How It Works

  1. Type a description of your meal (e.g. "2 scrambled eggs with toast and butter") or take a photo of your food. You can also combine text and image for even better accuracy.
  2. The app sends your prompt or compressed photo directly to OpenAI using your stored API key.
  3. OpenAI evaluates the input and calculates accurate nutritional estimates (calories, protein, carbs, fat, fiber, grams).
  4. Review and customize the portion sizes using serving multipliers, then save directly to your local history.

100% Privacy-First

Your API key and meal data remain stored exclusively inside your browser's local storage. No central database, no accounts, and no tracking.

Weight Progress Analytics

Track body weight changes alongside your daily nutrition intake with interactive charts, target lines, and progress percentages.
