Fixed Knowledge RAG

Chat over a predefined knowledge base owned by the company

What it is

The company pre-indexes its knowledge base once. Every user query retrieves relevant chunks from that fixed corpus and passes them to the LLM.

💡 Key insight

The knowledge base doesn't change at query time. Retrieval is fast and predictable. The main challenge is keeping the index fresh as documentation evolves.
