What Is RAG? How AI Answers from Your Own Documents

RAG (Retrieval-Augmented Generation) is the technique behind tools like NotebookLM. Instead of relying on trained knowledge (which can be outdated), RAG-powered AI searches your specific documents for relevant passages and uses those as the basis for its answer — dramatically reducing hallucination.

RAG Use Case Advisor
Help me understand when I should use RAG-based tools vs standard AI chat.

My use case: [DESCRIBE WHAT YOU NEED AI TO HELP WITH — e.g. "answering questions from our 200-page product docs"]
My concern: [e.g. "AI keeps hallucinating facts that aren't in our docs"]
My tools: [WHAT YOU CURRENTLY USE — ChatGPT / Claude / Custom tool]

Tell me:
1. Whether this is a good RAG use case and why
2. The simplest no-code RAG solution for my specific situation
3. The one thing that makes RAG fail even when it's set up correctly
4. How to verify that the tool is actually using my documents and not making things up
