Under the hood
Detect, estimate, look up.
The AI identifies the foods in the photo, estimates each portion, then looks the nutrition up in a database. Detection is reliable; portion size is where error comes from, which is why every tool lets you correct any step without starting over.
We publish how we measure this on the methodology page, and the research behind it, so you can judge the numbers yourself.
