📖 Overview

SmartChat is an AI-powered chatbot that uses TinyLlama (small LLM) and Retrieval-Augmented Generation (RAG) to answer questions with or without context from uploaded documents.

You can ask it anything – and if you give it a business report, summary, or any notes, it will search those and give better, smarter answers!
