What is RAG (retrieval-augmented generation)?
RAG means the AI first looks up relevant information, for example in your documents, and then writes its answer using what it found.
In real life
Like an open-book exam: instead of answering from memory, you find the right page first, then write your answer.

AI reply
Choose a question, then press “Ask the AI”.
Try the same question with lookup off, then on. Without it, the AI fills the gap with a confident guess. With it, the answer comes from the company's own document, and you can check the source.
