Claude Mem

A local AI agent memory engine records project history across sessions, with semantic search on your machine and optional cloud sync.

Claude Mem gives coding assistants persistent project memory, so developers can carry earlier decisions and failed approaches into later sessions without explaining them again.

Automatic memory captures agent activity as structured observations and summaries, then supplies relevant context to future sessions.
Project recall combines semantic and keyword search with project, date and type filters, plus a timeline showing the history around a result.
Selective context returns compact search results before retrieving full observations, limiting how much history enters the agent's context.
Agent connections support Claude Code, Cursor and other MCP clients, with integrations for Codex CLI, OpenClaw and Gemini CLI.
Memory viewer lets you inspect and search stored sessions through a local web interface.

The free, open source engine runs on your machine under Apache 2.0 and doesn't require an account. It stores sessions, observations and summaries in SQLite, and semantic recall runs locally. Windows is supported.

CMEM Cloud is a separate paid service that mirrors your observations database to hosted storage. Its offline-first sync shares memory across machines through a private MCP link, and its phone feed shows memory activity as it happens.
