Think about how you work today. You use Claude for writing. ChatGPT for research. Cursor for code. Maybe Codex for longer tasks.
Each one learns something about you. Your preferences. Your projects. Your decisions. But none of them talk to each other.
So you end up repeating yourself. Re-explaining context. Correcting assumptions that one tool got right weeks ago in a different conversation.
It is like having five assistants who each only remember the conversations they were personally in. They are all smart individually, but collectively they are forgetful.
