Retrieval-Augmented Generation (RAG)
Data“RAG”
4/5 · Advanced
A method where the AI looks up your real documents before answering, instead of guessing.
Lesson #2: Working With AI: Prompts, Data & Guardrails →Think of it like…
An employee who checks the filing cabinet before answering a customer.
Everyday example
A help chatbot that quotes the actual manual page for your appliance.
Construction example
An AI pulling your real permit records before answering a code question.
Business example
An AI answering HR questions straight from your employee handbook.
Why this matters
RAG is the main way businesses stop hallucinations and make AI answer from their own truth.
One-sentence summary
RAG makes AI look up your real documents before it answers.
Try it yourself
Pick one document your team gets asked about weekly. That's the first file you'd hand to a RAG system.
