What Onai does

Understand what you eat and how your habits change.

Instant scan 01

Point. Shoot. Know.

Take a picture of any dish. Get calories, protein, carbs, and fat in seconds. No barcodes, no manual entry, no database scrolling.

Recipes 05

Scan a dish. Cook it yourself.

Every scan includes ingredients, steps, and an editable recipe you can swap, simplify, or personalize before you cook.

Weekly Report 06

See your week at a glance.

Every week Onai gives you a nutrition summary across calories, protein, carbs, and fat. Spot patterns early and adjust before habits drift.
