A personal artificial intelligence agent can maintain task context, coordinate tools, anticipate routine needs, organize results, and decide when to ask for attention. Its usefulness comes from continuity and task fit rather than pretending to be a human identity.
Personal context is sensitive and can affect consequential actions. Users need visibility, consent, correction, deletion, permission controls, clear ownership, and safeguards that keep one person's data and authority from leaking into another account or task.
