🧠 m3 Memory
Give your AI a memory that lasts.
Your AI assistant is helpful until you start a new conversation and it has forgotten what you were working on. m3 fixes that.
Your assistants remember your projects, preferences, decisions and past work, even after you close the app, start a new session or switch to a different agent. By default everything stays on your own computer, and it works offline. m3 itself needs no cloud account or API key; your AI assistant may have its own requirements.
