In this project-based Generative AI tutorial, you will build a complete Retrieval-Augmented Generation (RAG) system from scratch using real-world concepts and tools.

This is Part 2 of our Generative AI series, where we move beyond fundamentals and implement a production-style AI system that can read documents and answer questions intelligently. Instead of just theory, you’ll build a working AI application step by step.

Whether you are a beginner or a developer, this video will help you understand how modern AI systems like ChatGPT work with private data using RAG architecture.

👨‍🏫 Instructor – Akarsh Vyas guiding you step-by-step through building a real-world RAG system in a simple and practical way.

📚 What You Will Learn in This Video
• What Document Loaders are and how they load PDFs into LangChain
• How Text Splitters break large documents into manageable chunks
• Understanding Embeddings and semantic meaning of text
• How Vector Databases store and retrieve information
• What Retrievers are and how they fetch relevant context
• How all components connect to form a complete RAG pipeline
• How AI systems answer questions using external knowledge

⚡ Project You Will Build
A complete AI system that:

• Loads a PDF book
• Splits it into smaller chunks
• Converts text into embeddings
• Stores them inside a vector database
• Uses a retriever to fetch relevant data
• Sends context to an LLM for answering queries
