Answer
Chat memory helps AI understand a chat's shared context like projects, decisions, preferences, goals, and chat norms, and is used only inside that same chat. Personal memory helps AI adapt to your own preferences, interests, communication style, and ongoing work when relevant. It is learned from your private AI chats and the group chats you take part in, and it is used only in your own private AI chats, never in group chats. Memory is kept up to date: newer information replaces outdated details, finished tasks drop away, and you can simply ask AI to remember or forget something.
