Zilliztech memsearch: Markdown-First Memory System for AI Agents Backed by Milvus — 1.4K Stars, Trending Python

GitHub·medium signal

Zilliz (Milvus creators) launched memsearch, a markdown-first semantic memory system for coding agents. Memories are .md files — human-readable, git-controllable, with Milvus as a rebuildable shadow index. 3-layer progressive retrieval (search→expand→transcript), hybrid BM25+dense vector search with RRF reranking, SHA-256 dedup, real-time file watcher. Plugins for Claude Code, OpenClaw, and OpenCode. Different from their earlier claude-context (code search) — this is persistent conversation memory.
