memU
Personal memory, stored as Wiki
Across Sessions. Across Agents. Across Devices.
memU is a lightweight, agent-driven memory system that gives users a shared LLM wiki across sessions, agents, and devices. It automatically distills your own reusable skills from your agent history. Its core memory logic is only 500 lines — compact enough to inspect, understand, and adapt.
Quick start
memU works with Codex, Claude Code, Cursor, OpenClaw, Hermes, WorkBuddy, Cola, pi, and more. See Host adapters.

Agent support
This matrix lists the currently tested memU integrations by operating system.
- Memorize — capture useful session knowledge through a scheduled background task and turn it into reusable memory.
- Retrieve — bring relevant memory into a future task.
- ⚠️ — supported with an important limitation; see the user note.

How it works
Automatic skill extraction
Once the scheduled bridging task is installed, memU can turn useful agent history into reusable Markdown skills automatically.
- Capture new sessions. The host adapter reads new session history, including messages and tool calls.
- Prepare self-evolve jobs.
prepare slices each session into a self-contained job with the paths and context the agent needs.
- Let the agent decide. The agent reads related existing skills, then chooses to do nothing, patch an existing skill, or create a new one.
- Write readable skill Markdown. Each skill has a name, description, and reusable workflow, including useful branches, edge cases, and pitfalls.
- Commit and index.
commit submits changed skill files through commit_results; memU embeds the skill name and description and stores it under the skill track.
- Retrieve it later. On a similar future task, memU returns the relevant skill so any connected agent can use the learned workflow.
The judgment and synthesis stay inside the agent. MemoryService makes no LLM or chat calls; it stores, embeds, and retrieves the skill Markdown the agent prepared.
Self-hosted
Private · Single-device · Embedding key required
To run memU locally with your own storage and embedding provider, send this message to your agent:
Read https://raw.githubusercontent.com/NevaMind-AI/MemU/main/SKILL.md and follow it to install memU.
Uninstall
To uninstall memU, send this message to your agent:
Read https://memu.pro/SKILL.md and follow its instructions to uninstall memU.
By default, uninstalling removes the host integration and tooling while keeping your memory store and ~/.memu/config.env, so a later reinstall can resume where you left off. Memory is erased only when you explicitly ask for it.
Host adapters: memory for desktop coding agents
memU runs as a sidecar to a desktop agent, one binary per host. Each binds two seams:
