Building Knowledge-Based Chatbots with RAG

A knowledge chatbot answers questions using your company data. It does not rely purely on general training.


1) System Architecture

  1. User query
  2. Convert query to embedding
  3. Retrieve top relevant chunks
  4. Inject chunks into prompt
  5. Generate grounded response

2) Why This Reduces Hallucination

Because the model is forced to answer based on retrieved documents.


3) Enterprise Use Cases

  • HR knowledge assistant
  • Policy document chatbot
  • Customer support AI

4) Summary

RAG transforms generic LLMs into domain-specific AI assistants.
