How to chat with your PDFs using local Large Language Models [Ollama RAG]

Summary

In this tutorial, viewers learn how to create a local retrieval-augmented generation (RAG) system for processing sensitive documents like PDFs. The presenter guides users through ingesting files, creating vector embeddings, and storing them in a vector database, enabling effective querying without internet access. By utilizing tools like LongChain and Chroma DB, the tutorial emphasizes secure and interactive document handling. Future plans include developing a user-friendly Streamlit app to simplify the process for non-coders, alongside exploring advanced techniques such as agents for improved functionality.
