Expert Knowledge Index

An expert knowledge index is a long-term memory store organized around a domain of expertise, such as YouTube strategy, business strategy, or product growth, that agents can consult when a project prompt needs specialist context ^[src-059].

Key points

• Roberts distinguishes personal conversation archives from expert knowledge: both are long-term memory, but one records what happened before while the other stores curated domain expertise ^[src-059].
• Pinecone is framed as the scalable option when the user wants semantic search across large records, books, transcripts, or many research notes ^[src-059].
• Obsidian is framed as the readable option when the user wants to inspect, edit, graph, and reason over markdown memory by hand ^[src-059].
• Firecrawl can gather web research for an expert index through a connector or MCP-style integration ^[src-059].
• NotebookLM can gather and organize research sources before the resulting knowledge is exported or embedded into Pinecone/Obsidian ^[src-059].
