Memsearch gives your AI coding agents a shared memory that persists across sessions and different tools. It stores memories as simple Markdown files, making them easy to read and edit, while using Milvus for fast semantic search. This means conversations and context from one agent (like Claude Code) are automatically available to others (like Codex CLI) without extra setup.
Memsearch is a cross-platform semantic memory system designed for AI coding agents. It provides a persistent, unified memory layer that works across multiple agent platforms including Claude Code, OpenClaw, OpenCode, and Codex CLI. The system uses Markdown files as the source of truth, making memories human-readable, editable, and version-controllable. Milvus serves as a shadow index for fast hybrid search (dense vector + BM25 sparse + RRF reranking). Key features include progressive retrieval with three-layer recall (search, expand, transcript), smart deduplication via SHA-256 content hashing, and live file watching for real-time indexing. Memsearch is ideal for agent users who want plug-and-play persistent memory, and for agent developers who need a robust memory and harness engineering toolkit via CLI and Python API.
Strong trust signals; still review the README and permissions before production use.

Give Claude Code persistent memory across sessions so it remembers past conversations and decisions.
Share context between different AI coding agents (e.g., Claude Code and Codex CLI) for seamless collaboration.
Store and retrieve project-specific knowledge, such as coding conventions, architecture decisions, and bug fixes.
Build custom AI agents with a built-in memory system using the Python API and CLI tools.
Enable progressive disclosure of information, starting with search results and expanding to full transcripts as needed.
Memsearch stores conversation data in Markdown files; ensure sensitive information is not inadvertently persisted.
The Milvus index is a derived cache; if deleted, it can be rebuilt from the Markdown files, but may cause temporary search unavailability.
File watcher auto-indexes changes; be cautious with large repositories to avoid performance impact.
