What is KnowKnow? How is it different from a regular food-logging app?

KnowKnow is an AI food-recognition app. Just snap a photo of your food and it automatically identifies it and estimates the calories and nutrients (protein, fat, carbs)—no need to look everything up item by item. It comes with built-in food nutrition databases for the US, Japan, and Taiwan, so you can find everything from local street food to imported products. Best of all, we have broken free from the limitation of only being able to fill out a form: you just chat, snap a photo, or type a few words to complete a professional nutrition log. It also remembers your past conversations like a friend, offering two-way interaction and thoughtful care.
