Synapse is an AI-driven health chatbot designed to provide personalized medical insights, recommend doctors, and set health reminders. It utilizes Retrieval-Augmented Generation (RAG) with LLM-based response generation, ensuring accurate and context-aware interactions.
✅ LLM-powered health assistant – Provides accurate medical insights using AI.
✅ RAG (Retrieval-Augmented Generation) – Enhances response accuracy by retrieving relevant medical knowledge.
✅ Doctor recommendations – Matches symptoms with the best-suited doctors.
✅ Medication & appointment reminders – Helps users stay on track with health schedules.
✅ Scalable & efficient – Built with vector databases for fast retrieval (<200ms).

The chatbot follows a modular RAG-based architecture:
1️⃣ Data Ingestion: Collects structured/unstructured health data from trusted sources.
2️⃣ Vector Database Storage: Stores embeddings for fast and efficient retrieval.
3️⃣ Query Processing: Maps user inputs to medical context and retrieves relevant data.
4️⃣ LLM Response Generation: Generates conversational responses based on retrieved medical insights.
5️⃣ Doctor Recommendation System: Uses ML-based symptom classification for personalized recommendations.
6️⃣ Reminder System: Notifies users about medications, appointments, and health checkups.
