Mintlify Replaces RAG with Virtual Filesystem for AI Documentation — 312 HN Points

Mintlify·medium signal

Mintlify published a detailed technical post on replacing their RAG pipeline with a virtual filesystem approach for their AI documentation assistant, generating 312 HN points and 118 comments. The architecture treats documentation as a navigable filesystem rather than a vector-similarity search problem, allowing the AI to browse, stat, and read files in a structured way. Builder-relevant: a concrete alternative to RAG that's working in production.
