Prefit.AI
FreeEstimates calories and macros from a photo of your meal
What is Prefit.AI?
Prefit.AI looks at photos of a meal and estimates calories, protein, carbs and fat for each item, plus checks on fiber, added sugar, sodium, whole foods and vegetables. It runs in the browser with no account, and is meant for people tracking their diet who don't want to type in every food.
You can upload up to four photos or a short video of a plate. A vision model identifies each food, judges portions from cues such as plate size and cutlery, and adds likely hidden calories from oil or dressing; a short note like 'large portion' helps it get closer.
The site says estimates are usually within about 20% for simple meals and less precise for mixed dishes, and that it isn't medical advice. Photos aren't saved after the estimate, and results can be shared as a postcard image on Instagram, Facebook or X.
