Daizu vs Cal AI: nutrition program or ultra-fast photo scan?
Cal AI and Daizu both use visual AI, but with very different roles in 2026: Cal AI is an ultra-fast photo-first tracker (photo → calories in a few seconds, subscription required for the AI scan); Daizu builds a custom nutrition program, a grocery list, and uses the scan for off-plan meals. Choose Cal AI if you only want to log what you already eat, fast; choose Daizu if you want to decide what to cook ahead of time.

Ce que Daizu fait mieux
- A custom nutrition program plus a grocery list — Cal AI does not plan your meals; it logs what you already eat.
- Guided cooking mode and portions calibrated to your profile (goal, allergies, diet).
- Photo scan built into the program (200/day): unplanned meals add to the day’s total, not to a standalone diary.
- Data hosted in the EU — Cal AI (Viral Development LLC) is based in the United States.
Ce que Cal AI fait mieux
- An ultra-fast photo workflow — open, photograph, confirm: logging takes a few seconds (the core of the product).
- Volume estimation via a depth sensor plus AI (calories, protein, carbs, and fat from a photo).
- An annual price that is often aggressive on promo (about €19.99–€29.99/year depending on the store offer) — cheaper than Daizu if you do not cook.
- Apple Health, Apple Watch, streaks, and social groups for day-to-day motivation.
Lequel choisir si…
Someone who mostly eats out or eats ready-made meals and wants to log in 3 seconds
→ Cal AI
Cal AI is optimized for logging after the fact. If you almost never cook, Daizu’s program and grocery list do not add much.
A household that cooks on weekdays and wants a program and list ready to go
→ Daizu
Cal AI generates neither menus nor groceries. Daizu builds the program calibrated to your profile and sorts the list by aisle.
A tight budget that only needs photo scan, with no meal planning
→ Cal AI
Cal AI’s annual plan often lands around €20–€30 on a store promo, versus €99.99/year for Daizu. That only makes sense if you do not need a program or a grocery list.
