StrataFS is an open-source semantic filesystem for the AI era. Index local and cloud storage, search with hybrid FTS5 + vector retrieval, and expose your data to AI agents via a native Model Context Protocol (MCP) server — no SaaS, no API calls, no lock-in.https://stratafs.neullabs.com/en-ushttps://stratafs.neullabs.com/blog/stratafs-vs-elasticsearch-for-developers/https://stratafs.neullabs.com/blog/stratafs-vs-elasticsearch-for-developers/Elasticsearch is the workhorse of full-text search. StrataFS is the new workhorse of embedded semantic search.
