What is the elegant way to build a proper knowledge base?

It depends on your purpose – you don’t need a knowledge base for everything, but it’s useful for letting an AI answer business‑specific questions that would otherwise require a database query. For example, I would feed all publicly available information about me, my company (Left Click Software), and our major case studies into the system. I’d host the chatbot on a platform like Botpress or NLU and connect it directly to Claude via API. The system prompt would contain a simple template with a few conversation routes to keep answers constrained. All the data would be embedded in a vector store such as Pinecone, and Claude would query Pinecone for the top five to ten matches before responding. This is standard RAG: each incoming message triggers the system prompt, a Pinecone similarity search, injection of the results into the prompt, and then the answer. The key is to be specific – you can’t feed everything – and to consider security, since exposing internal data through a public model can leak sensitive information.
