The challenge
Food diaries die on day three. Typing every meal is tedious, and calories from a single AI guess are often off. The product had to make logging effortless, keep the numbers trustworthy and stay fast inside a messenger on an ordinary phone.
What we built
A three-stage AI pipeline. A vision model lists the products and estimates weights. Each product is then researched in parallel across nutrition sources and cross-checked, and the totals land in the diary. Progress streams live, in the chat and in the app. The Mini App is plain HTML, CSS and JS with a liquid-glass look and fullscreen mode on phones. We cut it from 125 requests to 8 and the start from 8-16 seconds to 1-2.
