Sixty seconds, then five minutes.

1. The problem. Every time parents go out, someone else holds their child's safety: a babysitter, a grandparent, a nanny. What they need to know lives on a fridge note, in a WhatsApp thread and in a parent's head, and the questions come at the worst moments.
2. The add-on. The Echo Show in the kitchen becomes the sitter's guide for the evening, in the parents' own words. Questions the notes don't answer go to the parents' phones and the answer comes back. In an emergency it reads the family's own plan, one step at a time, and keeps going when the internet drops.
3. Why it's different. Safety is enforced in code, not a prompt: never "it's safe", never a dose, emergencies first, the address shown and never spoken. Measured on 357 things a sitter might say, with the first run on 120 lines another AI wrote without seeing ours (85%) reported as the honest number.
4. Why Alexa+. It uses what makes Alexa+ add-ons more than chat: MCP Apps cards on the Echo Show, tasks that wait for a person, elicitation for a form and for paying on the parent's phone, and a house that knows the doorbell and the TV.

Or start with the 3-minute video: the whole evening, with the emergency at 1:16. How it was built, and what testing taught me, is in the build story on dev.to.
