This project is an open-source, AI-powered health and nutrition management platform designed to deliver localized dietary analysis tailored specifically for Nepali society. By combining computer vision with South Asian health metrics, the system calculates personalized BMR, TDEE, and protein targets while accurately evaluating traditional meals like Dal Bhat and Momo. The application features an interactive meal planner , a bilingual AI assistant named Poshan Sathi (पोषण साथी), and a dedicated export tool that generates clinical health summaries for medical consultations. In Nepal, where traditional dietary tracking has long been neglected by generic Western health apps, this platform bridges a vital technological gap by bringing local food context into modern AI wellness tools. Its intuitive interface seamlessly toggles between English and Nepali (नेपाली), eliminating accessibility barriers for users across diverse age groups and technical backgrounds. By translating everyday meals into precise, actionable health data, the project empowers individuals to optimize their nutrition while remaining deeply connected to their cultural culinary heritage. Ultimately, KhanaAI serves as a transformative bridge between artificial intelligence, public health awareness, and traditional Nepali lifestyle.
