The CareThread
Built at Meta Global AI Developer Hackathon · Oct 26, 2026 · Remote

63 million Americans care for an adult family member or aging loved one, and that coordination lives in group chats, where commitments quietly die: a pharmacy pickup nobody confirmed, a cardiology follow-up nobody booked, a benefits form nobody filed. CareThread gives every loved one their own thread. It shows every commitment in that thread, detects what is aging, states what is blocking each one, proposes the next move, and writes every proposed action to a consent ledger (action, evidence, cost, who approved or rejected it), so nothing runs on a family member's behalf without a recorded yes. When an action is approved, Cora, the care agent, carries it out, including placing the call herself, as she already does in the production CareThread. Two features run on Meta models in this demo: a pill organizer photo check (SAM 3.1 segments the organizer, Muse Spark reads it against the medication list) and a one-sentence whole-outcome plan for the week (Muse Spark). Built fresh for this event on the Meta Model API, with a fully fictional family and invented data.
