Santa Adventure Club

Santa writes back, all season, on your child's iPad

Parents set up a story for each child, and Santa sends messages through December that remember what the child told him. Parents can also send a message as Santa in seconds.

Who it is for
Parents of kids young enough to still write to Santa

In App Store and Play review

What it does

Pick a story that fits the child

Choose by age and length, from a seven-day adventure to a full advent mystery. Add their name, their friends, and what they are hoping for.

Messages that remember

Santa replies to what a child actually said earlier in the season, so the thread reads like someone listening rather than a schedule of broadcasts.

Send a message as Santa

Caught them sharing a toy or cleaning their room? Write it in the parent app and it appears exactly like the rest of Santa's messages.

Puzzles a pre-reader can play

Nightly puzzles that need no reading at all, so the youngest kids can take part on their own.

Consent recorded per child

Sending a child's details to an AI model is permitted per child, withdrawable in settings, and recorded as append-only evidence. The gate sits ahead of everything else.

How it is built

  • Next.js parent app and marketing site on Vercel
  • Expo app for the child's iPad, with the season's messages cached for offline reading
  • Supabase for accounts, children, stories, and consent history
  • Claude for the storytelling and for the safety classifier that screens it
  • Stripe billing that scales with the number of children, priced per season
