About Calorie Estimate
Calorie Estimate is a free, AI-powered food nutrition calculator. Snap a photo of any meal or describe what you ate and get an instant breakdown of calories, macros, and micronutrients — powered by GPT-4o. No account, no subscription, no calorie database to search through.
How It Works
Snap a photo or describe your meal
Upload a photo of your food or type a plain-text description — 'two scrambled eggs, toast with butter, and a small orange juice'.
AI identifies every ingredient
Calorie Estimate uses GPT-4o to recognize individual foods, estimate portion sizes, and look up their nutritional values.

Within seconds you receive calories, protein, carbs, fat, fiber, and ten micronutrients — plus a nutrition rating and coaching tips.
Track your daily intake
Logged meals stack up on your dashboard so you can see macro progress toward your daily goals in real time.
Features

Point your camera at any meal — home-cooked, restaurant, or packaged — and get an instant nutritional breakdown. No barcode scanning or manual food database searching required.
Macro & Micronutrient Tracking
Set personalized daily goals for calories, protein, carbohydrates, and fat. Track progress with ring charts and monitor 10 micronutrients including fiber, sodium, vitamins, calcium, and iron.

All meal logs are stored in your browser's local storage. No account, no sign-up, no data uploaded to a server. Your nutrition history is yours alone.
Instant Results
Analysis typically completes in 2–5 seconds. You get a per-item breakdown, totals, and personalised coaching feedback — all without leaving the page.
Powered by GPT-4o
Calorie Estimate uses OpenAI's GPT-4o, one of the most capable multimodal AI models. It understands food context, mixed dishes, portion sizes, and cooking methods.
Who Is It For?
Calorie Estimate is built for anyone who wants to understand what they're eating without the friction of traditional calorie-counting apps. Whether you're trying to lose weight, build muscle, manage a health condition, or simply eat more mindfully — knowing the nutritional content of your meals is the first step.
It's especially useful for people who eat a variety of foods, cook at home, or order takeout frequently — situations where barcode-scanning apps fall short.
