What Retrieval-augmented generation (RAG) means

RAG lets a chatbot answer from your own policies, services and FAQs instead of guessing from general training data. It makes answers more accurate and easier to keep current. It is the usual approach for business chatbots and internal knowledge tools.

Why it matters for your website

RAG helps AI tools answer using your real documents instead of guessing. That makes a support chatbot or internal assistant more accurate and up to date with your policies and services. It also lets you point to sources, which builds trust in the answers.

Example

A property management company builds a chatbot that searches its lease guides and FAQ pages before answering tenant questions. When a tenant asks about pet fees, it quotes the current policy.

Tips

  • Keep the source documents accurate and current, since the AI relies on them.
  • Show sources or links with answers so users can check them.
  • Leave out private or sensitive documents unless access is properly controlled.

Common mistakes

  • Feeding the system outdated documents and getting outdated answers.
  • Assuming RAG eliminates all wrong answers, so nobody tests or reviews it.
