Mom asks. You say OK. PayPal pays.

Your parent shops from their own phone, and you approve from yours. No more logging in as them or reading out card numbers.

In a survey of 657 US adults, about 1 in 10 had signed in to someone else's money or medical account with that person's login. Foong et al., Journal of Medical Internet Research, 2025.

Sandbox money only. Nothing real is bought. This is a hackathon build: what's real, what stands in, and what comes next.

Try both sides now, with no sign-up: Rose, who asks, and Sam, who says OK. First, link Rose's sandbox PayPal on PayPal's own page, or skip to a demo one.

How it works

  1. Your parent says what they need. In their own words, or a photo of the thing or of a written list: batteries, a night light, a phone charger.
  2. AI finds real options. Up to three listings for each thing, under your limit, each explained plainly: what it is, why it fits, and what to watch for.
  3. You say OK from your phone. Your phone buzzes with the ask. One tap pays with their saved PayPal, and you both get the receipt.

You stay in charge

  • Nothing is bought without your OK. Untick anything you don't want, and it goes back to your parent.
  • You set the limits. A price for each item, and a total for each ask.
  • No passwords change hands. PayPal keeps the payment details, linked once from your parent's phone.
