Household software
A private assistant for one home. It answers questions, keeps a shared memory, and connects to the household's own calendar, lists, and devices.
Reads and adds events on a household member's own connected Google Calendar - "add dentist appointment Tuesday" becomes a real calendar entry.
Tracks shopping lists, tasks, bills, and smart-home devices for the household, through each service's own account.
Remembers things it's told across conversations - preferences, schedules, ongoing plans - so the household doesn't have to repeat itself.
