Apache-2.0

What it does

Distils what is worth keeping out of your agent history into a wiki-shaped memory that follows you between conversations, tools and machines, and pulls reusable skills out of past work along the way. The core logic is around 500 lines — small enough to read and adapt, which is unusual in this category. Adapters exist for Codex, Claude Code, Cursor, OpenClaw and others. "Free and unlimited" describes the hosted service, so check where your memory actually lives. Apache-2.0.

Summary based on the project's own description. The Japanese page has a fuller beginner guide: setup difficulty, what to prepare, and a step-by-step start.

memU FAQ

Is memU free?: Yes. It runs on your own machine, so there is no usage-based cost either.
Do I need to install anything or write code to use memU?: It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.
Does memU work on a phone?: No. It needs a computer.
Can I use memU commercially?: The licence is Apache-2.0, which permits commercial use. Conditions such as keeping the copyright notice still apply, so read the licence text before shipping it inside something.
