A photo, text, voice action, or shared record supplies evidence. None is a direct measurement of every ingredient or gram.
How Feast works
A useful food record is built, not merely recognized.
Feast begins with a fast first draft, gives corrections the same status as model inference, and uses history for questions a single meal cannot answer. These guides explain the workflow, the evidence boundary, and the failure test for every capability.
Correct ingredients, brand, preparation, portion, time, or photos and reanalyze. Contradictions deserve review, not concealment.
Use repeated records to study nutrition and sleep patterns, then separate an interesting association from an individual causal claim.
1 · Build a defensible meal record
Capture evidence, then add what the image cannot know.
These guides cover the core estimation loop: photograph, review, correct ingredients and amounts, and preserve enough context for the record to remain useful later.
