Why KB builders hit a wall
Publish Stack Fragmentation
Obsidian for writing, Quartz for static HTML, Stripe for gating, a RAG pipeline for chat — four tools, four failure points before your KB product ships.
Flat Docs, Dumb Retrieval
GitBook and generic RAG treat every page equally. Agents pull wrong chunks, miss canonical sources, and hallucinate when context is ambiguous.
Expertise Trapped in Vaults
Your best reports live in Obsidian or Notion — private, unindexed, unmonetized. Turning expertise into a product means months of custom engineering.
