EGO is a personal context layer and "AI passport" that stores a user's preferences, history, relationships, and identity so it travels across the AI apps and assistants they use, letting people avoid reintroducing themselves each time. It offers privacy controls over what each application can see and includes an optional public profile page (at ego.ist/i/you) for sharing interests and links.
