Master Retrieval-Augmented Generation: Build, & Deploy a Complete AI-Powered Document Chat Application from Scratch
What you'll learn
Understand how text embeddings convert human language into numerical vectors that capture semantic meaning, enabling similarity-based search
Describe the complete RAG pipeline including the five key stages.
Explain what Retrieval-Augmented Generation (RAG) is and articulate why it's superior to fine-tuning for document-based question answering applications
Set up a professional Python development environment with virtual environments to isolate project dependencies
Create and manage a requirements.txt file to document and install project dependencies efficiently
Securely manage sensitive credentials like API keys using environment variables and Streamlit's secrets management system
Read and extract text content from various document formats such as PDF and TXT.
Chunk large documents into smaller segments suitable for retrieval.
Generate embeddings using the OpenAI API for semantic search.
Store and index embeddings efficiently using a vector database.
Execute similarity searches to retrieve relevant document chunks.
Build core RAG logic that connects retrieval and generation into a working pipeline.
Create an interactive Streamlit application for document chat functionality.
Upload documents and ask questions that return grounded and cited answers
Test the RAG application using real-world documents.
Deploy a working RAG system to Streamlit Cloud for public access.
