In PlateDiary

A rough number for the dishes you save — only if you want one.

Off unless you turn them on

Calories in PlateDiary are off unless you turn them on. Switch them on and, when PlateDiary AI reads your photo of the table, each dish gets one rough “~” number. Accept it or change it; a number you correct is remembered for that dish. With Calories off, the app looks exactly as it did before.

A read sends small pictures of the cut-out dishes, with the place's name as a hint — never the table photo, faces or your location. Calorie numbers never go to analytics, and nothing is written to a health app. PlateDiary AI starts with free tries; here is how it works.
