Mintlify replaced traditional RAG systems with a virtual filesystem approach to improve their AI documentation assistant's performance and relevance.

Mintlify moved away from conventional Retrieval-Augmented Generation (RAG) to implement a virtual filesystem architecture for their AI assistant

The virtual filesystem approach provides better organization and retrieval of documentation by mimicking file system structures rather than vector similarity searches

This architectural change aims to improve the accuracy and contextual relevance of responses when assisting with documentation queries

The solution represents an alternative approach to RAG that may offer better scalability and maintainability for documentation-heavy applications
