Every AI tool has its own memory silo. Claude knows what you told it. ChatGPT does not. Cursor has never heard of either. OMP is an open protocol that fixes this. One memory server, all your tools. Claude saves via MCP automatically. The browser extension tracks ChatGPT conversations and generates a handoff brief when you open a new AI. There is a mobile PWA live right now, no install needed. Apache 2.0. Self-host or use the free hosted server.
