MedAI is a fully local medical AI chatbot built with Python/Flask, LangChain, and Ollama (LLaMA 3.2). It features dual-mode interaction — Patient mode for plain-language guidance and Doctor mode for clinical, evidence-based responses. The app maintains full conversation memory, renders markdown responses, and supports theme toggling. All inference runs locally, ensuring complete data privacy. Built as a full-stack AI project integrating a REST/SocketIO backend with a responsive dark-mode frontend.
