What it does
memU saves useful knowledge from your sessions with AI agents and brings it back for future tasks. It works with tools such as Claude Code, Codex, Cursor and ChatGPT's work mode.
It can also turn past work into reusable written "skills" automatically. Its makers say the core memory logic is about 500 lines of code. You get an API key from the memu.so service to start.
