Build an end-to-end RAG chatbot for your personal e-book collection using the Unstructured Platform and MongoDB

This guide provides a comprehensive tutorial on building a Retrieval-Augmented Generation (RAG) application that functions as a personal AI librarian, enabling users to explore their digital book collections. The process involves constructing an unstructured data ETL pipeline for EPUB files using the Unstructured platform, utilizing MongoDB Atlas as a vector store and search index, and orchestrating the RAG workflow with LangChain. Users will also learn to develop an interactive user interface with Streamlit, powered by a local llama3.1 model through Ollama, resulting in a fully functional RAG application capable of delivering precise and instant responses. The Unstructured Platform simplifies the ETL process, offering a no-code interface that empowers non-technical users, while advanced features like image and table summarizers enhance the application's performance. The application integrates MongoDB and LangChain for efficient data retrieval and uses Streamlit to create an engaging UI, ultimately providing a responsive and context-aware digital library assistant.
