Myeline is a memory layer for AI assistants that connects to Claude, ChatGPT, and any client using the MCP protocol. It stores facts it learns about you, each with a source, ensuring transparent responses. If it finds no matching information you approved, Myeline says so instead of guessing. The name comes from myelin, the sheath that insulates nerve fibers for quick, accurate signal transmission. Myeline functions as an intermediary between your AI and its memory, requiring your approval.
