A shared whiteboard for two people, each with their own Ariadot account. Your AI watches your inbox, your partner's watches theirs, and both can propose entries into one shared book you both see and edit. The school newsletter lands in one inbox, the piano-class email in the other, and both end up on the same shared board after a tap.

Think the fridge whiteboard for a household: term dates, the after-care pickup rule, the plumber's number. It is separate from your private handbook, and nothing reaches the shared board without a human accepting it first, with full provenance (added from your partner's inbox).
