Meet EverOS: An Open Source Markdown-First Agent Memory Runtime With Hybrid BM25 + Vector Retrieval and Self-Evolving Skills

- EverMind dropped EverOS, an open-source memory runtime that actually admits LLMs are stateless morons. Instead of locking data in a black-box vector DB, it writes agent memories as plain Markdown files indexed by SQLite and LanceDB. It’s local-first, Apache 2.0 licensed, and uses hybrid BM25 + vector retrieval to stop agents from hallucinating their own past. They claim "self-evolving Skills" where repeated tasks become reusable code, which is just fancy talk for not forgetting how to tie your shoes every session. Benchmarks look decent, but verify them yourself because EverMind’s numbers are about as trustworthy as a Chrome Syndicate debt contract. At least it doesn’t require a meat wallet to self-host.
