A knowledge base chatbot is an AI chatbot connected to a collection of approved information. It retrieves relevant content and uses it to answer user questions.
In practice
This is a common business use of RAG. The chatbot can answer from service pages, onboarding guides, return policies, help center articles, product specs, and internal notes.
What to watch
The bot is only as good as the knowledge base. Outdated pages, missing policies, or unclear documents lead to weak answers.
