AI assistants
Your food diary,
Your food diary,
inside your assistant.
Connect eatnibble to ChatGPT, Claude, Gemini, Grok or Cursor. Tell it what you ate and it estimates each item's portion, calories, protein, carbs and fat, then saves the meal to your eatnibble diary. Ask about your day, and it knows.
What it can do
Log it, fix it, ask about it.
“That omelette was 3 eggs, not 2”
Fix or remove a meal
Corrects or removes a meal from the last 7 days — only when you ask. A corrected meal waits for your review in the app, and the assistant is asked to check with you before removing one.

Last step
Approve the connection on your iPhone.
In the eatnibble app, go to Settings → AI Connections → Connect an Assistant and enter the 6-digit code.
The app shows which assistant is asking and what it will be able to do. Tap Connect, and the browser page returns you to your assistant. The code expires after 10 minutes.
Your data
Your food log stays on your iPhone. While an assistant is connected, the app shares a short summary of the last 7 days of meals (name, time and totals) so the assistant can answer questions, and meals the assistant logs or corrects wait on our server only until the app picks them up. Meal photos, your profile, your daily goal and any Apple Health data are never shared. See the Privacy Policy for details.
Disconnect
In the app, go to Settings → AI Connections, swipe the assistant (or open it) and choose Disconnect. When the last assistant is removed, the summary on our server is deleted. Deleting your account removes everything.
