Gutlog: a food diary with confidence tiers

Field notes

For each meal, the assistant drafts foods, weights, and likely ingredients; Gutlog matches entries against a food database, the user's own foods, and a barcode index. The page says known-product scans are instant and label photos for new products are indexed for later users. The symptom diary tracks bloating, pain, reflux, stool form, and energy; suspected triggers are treated as hypotheses, with “not enough data yet” shown until there is enough.
