AI Food Calorie Scanner
Take a picture of your food and count calories instantly. The same AI that powers the Calzy app — free in your browser, no sign-up.
How the calorie scanner works
AI breaks down the meal
The model identifies every component — the protein, the sides, the sauce — and estimates the weight of each.
Get calories, macros & Health Score
See total calories, protein, carbs, fat, fiber, sugar and sodium, plus an A–E Health Score with what's good and what's not.
How accurate is a photo calorie count?
Honest answer: good, not perfect. Food recognition — “that's grilled chicken, rice, and broccoli” — is the reliable part. Portion estimation from a single 2D image is the hard part, because a photo can't perfectly convey depth or density. That's why the scanner shows you a per-ingredient breakdown instead of one opaque number: you can sanity-check each component.
For everyday tracking this trade-off wins, because the alternative isn't lab-grade weighing — it's guessing, or not logging at all. Research on food logging consistently shows that consistency beats precision. A 3-second photo you actually take every meal outperforms a food scale you abandon after two weeks. We wrote more about this in how accurate calorie counter apps really are and how AI calorie tracking works.
Tips for better estimates: shoot from a slight angle (not directly overhead), get the whole plate in frame, and include a reference object like cutlery when portions matter. In the Calzy app you can also correct any ingredient's weight after a scan and the totals recalculate.
FAQ
Is this food calorie scanner really free?
Yes — you get 2 free scans in the browser, no sign-up and no credit card. After that, the Calzy app scans without limits on its free tier.
How accurate is calorie counting from a photo?
The AI identifies the foods on your plate and estimates portions from visual cues. For common meals the calorie estimate typically lands close to what a nutrition label or database lookup would give, but portion size from a single 2D photo always carries some error — treat the result as a solid estimate, not a lab measurement. Weighing food remains the gold standard for precision.
How does the AI calorie scanner work?
Your photo is analyzed by a multimodal AI model — the same one the Calzy app uses. It recognizes each visible food, estimates the weight of every component, computes calories and macros per ingredient, and sums them into the total you see, along with a 0–100 Health Score.
What happens to my photo after scanning?
The photo is processed for the duration of the analysis and is not stored permanently. See our privacy policy for details.
Can it scan packaged products and restaurant meals?
Yes. If a brand logo is visible it identifies the product; for restaurant dishes it estimates the menu item. For packaged foods, the Calzy app's barcode scanner (300,000+ products) gives exact label values instead of estimates.
What's the difference between this and the Calzy app?
Same AI, same analysis. The app adds unlimited scanning, a daily food log, portion corrections, barcode scanning, additive detection, weight tracking, and goals — so every scan lands in your daily calorie budget automatically.
