Markdown-first persistent memory by Zilliz (creators of Milvus).

Cross-platform semantic memory for AI coding agents, by Zilliz (creators of Milvus). Session summaries live as Markdown files — the source of truth — indexed with hybrid dense + BM25 search for recall on every prompt. One memory flows across Claude Code, OpenClaw, OpenCode, and Codex CLI, and it can distill repeated workflows into reusable agent skills. MIT licensed.

Reviewed review. These are observations, not a security certification.

Things to check

  • Default backend is embedded Milvus Lite — a single local file, no server to run; Zilliz Cloud or self-hosted Milvus are optional upgrades for team setups. Markdown files remain the source of truth and the vector index is a rebuildable cache, but recall quality still depends on how well sessions get summarized.
