Onai: Food & Nutrition AI

Why it helps

Scan food first. Log it when you actually eat it.

No database search

Take a picture of a meal, snack, drink, or restaurant dish and get a useful macro estimate.

Scans and meals stay separate

Keep scans in your history. Add only the meals you ate to your diary.

Weekly progress is clear

See your logging, protein, balance and habit progress without digging through charts.

Meal ideas use your diary

Onai uses your recent meals, goals and remaining macros to suggest what to eat next.
