memU

What memU does

memU gives users a shared LLM wiki across sessions, agents and devices and automatically distills reusable skills from agent history. The README says its core memory logic is only 500 lines, compact enough to inspect and adapt. A scheduled background task captures new session history, including messages and tool calls, slices it into self-contained jobs and lets the agent decide whether to do nothing, patch an existing skill or create a new one as readable Markdown.

Setup is agent-driven: you get an API key from memu.so and send your agent a message telling it to read https://memu.pro/SKILL.md and follow the instructions. The README's matrix lists Hermes Agent as supported for both memorize and retrieve on macOS. On Windows memorize works and retrieve carries a warning that a memU version with Windows HERMES_HOME support is needed. Hermes Agent does not appear in the Linux table. Other listed hosts include Codex, Claude Code, Cursor, OpenClaw and WorkBuddy.
