NanoRhino

AI Nutrition Coach by Message by NanoRhino is a text-based dietary coaching service that operates directly inside messaging apps like WhatsApp. Users begin by calculating their total daily energy expenditure through a brief five-minute AI interview, which establishes daily calorie targets and protein minimums tailored to their lifestyle, dietary restrictions, or medication regimens.

Rather than requiring manual database searches or barcode scanning, the coach allows users to log meals by sending photos, text descriptions, or nutrition labels directly in chat. The system responds with macronutrient breakdowns, remembers context, accepts plain-language log corrections, and delivers weekly progress reports. Instead of a standard monthly subscription, the platform uses a pay-per-pound pricing model where users only pay when weight is lost.
