Log meals
Log a meal by showing it or saying it
A photo, a sentence or a barcode in ChatGPT or Claude, and the meal is in your diary with calories, macros and an ingredient list that says how sure it is. Fix anything in one more sentence. Logging from your assistant is free and unlimited.
Things to say
Copy one, or open it in a new chat with it already typed in. Replace the brackets with your own photo.
[a photo of your plate] Log this lunch. I ate about half the rice and all of the fish.
Log two eggs, a slice of sourdough toast and a flat white for breakfast.
[a photo of the barcode] Log one serving of this.
The chicken was more like 200 g, and there was no cheese on it.
Same breakfast as yesterday.

How it works
What your assistant does, and what Gutlog does
- 1
Your assistant looks
It already sees the photo, so it sends a draft: each food, a portion estimate and the ingredients it is sure of and the ones it only suspects.
- 2
Gutlog matches and stores
Every item is matched to the food database, portioned and scored. A meal is always stored, even when something is unsure; nothing is lost.
- 3
You fix it in a sentence
Confirmed ingredients count, likely ones count, possible ones are asked about. Your edits always win over estimates and every change is kept.
Under the hood
The tools your assistant calls
You never say their names. Each one is also a REST call, a CLI command and an SDK method.
Not connected yet?
One sentence connects your assistant
Paste it into ChatGPT, Claude or your coding agent; it reads the instructions and either connects itself or gives you the exact clicks.
