Chapter 11: Software 3.0 | NotebookLM as RAG

11.1 What Is RAG?

You've learned what AI is, from the hand-written rules of Software 1.0 to the learned models of 2.0 and the generative chatbots of 3.0. Now you wield it. In Chapter 10 you saw why a chatbot can sound confident and still be wrong: it's guessing plausible next words with nothing anchoring it to the truth. RAG fixes that by handing the AI your own trusted sources to answer from. This chapter turns a confident guesser into a grounded research partner, using a free, no-code tool called NotebookLM.
