Ami answers questions about your own household using the accounts you already have. Connect your email, calendar and files, then ask what bills are due this month, what the school sent about the field trip, or when the car insurance renews, and Ami answers with the message or document it found. Everything is read only. Ami never sends mail, edits your calendar or changes a file, and you can disconnect any account at any time. Add the people in your family once and every answer is split out per person. Documents you add are read on your iPhone and the file itself is never uploaded. When Ami finds nothing, it says so instead of guessing.
