RAG is not a chatbot: designing a trustworthy knowledge system

A RAG system is often introduced as a chatbot, but the useful part is the knowledge layer behind it. The system has to retrieve the right material, respect access boundaries, explain where answers came from and fail gracefully when the answer is not supported.

Useful design questions

• Which documents are approved for use?
• How are updates, deletions and permissions handled?
• What answer format helps the user act safely?
• How are retrieval quality and answer quality evaluated?

The strongest systems combine content governance, search, prompting, UI design and ongoing review instead of relying on a model alone.
