Ayurveda Chatbot using LLaMA and RAG

This project is an interactive Ayurveda chatbot that uses a Retrieval-Augmented Generation (RAG) pipeline powered by the LLaMA language model via Ollama. The chatbot provides Ayurvedic knowledge and answers user queries based on pre-trained PDF content.

Features

PDF Knowledge Base: Pretrained on Ayurvedic texts for domain-specific answers.
RAG Pipeline: Combines FAISS vector retrieval and LLaMA for context-aware responses.
Streamlit Interface: Easy-to-use frontend for interacting with the chatbot.

Requirements

Python 3.8+
GPU support (optional but recommended for faster LLM inference)
LLaMA model via Ollama
