## Overview

MedAI is a health-information web app combining a local symptom/chat assistant, medicine lookup, prescription-upload demo, emergency guidance, and a health-history dashboard backed by an Express API and MongoDB. The evidenced consultation path is symptom entry in the chat page, local analysis in the data module, and a displayed response; dashboard records have a separate authenticated backend path. The prescription page simulates analysis rather than calling an OCR service. Frontend API wiring and unsampled page behavior are not asserted here.

Main entry points: [`ai-doctor/src/app/chat/page.tsx`](https://github.com/rohit-create-ctrl/agentic-ai-doctor-and-chatbot/blob/main/ai-doctor/src/app/chat/page.tsx) (Consultation chat), [`backend/server.js`](https://github.com/rohit-create-ctrl/agentic-ai-doctor-and-chatbot/blob/main/backend/server.js) (Express server), [`backend/routes/dataRoutes.js`](https://github.com/rohit-create-ctrl/agentic-ai-doctor-and-chatbot/blob/main/backend/routes/dataRoutes.js) (Record routes), [`ai-doctor/src/app/page.tsx`](https://github.com/rohit-create-ctrl/agentic-ai-doctor-and-chatbot/blob/main/ai-doctor/src/app/page.tsx) (Home)
