Show HN: I created an AI Santa for my kids so I don't have to impersonate one

As a developer and a father of two young kids, I’ve faced a uniquely modern parenting problem this holiday season: keeping the magic of Santa Claus alive in an age of tech-savvy children.

When I was a kid, my parents had all sorts of tricks to keep the illusion of Santa intact. They’d rope in distant relatives to call pretending to be Santa or my dad would disguise his voice (poorly) and "Ho ho ho!" over the phone. But let’s face it— those tactics don’t work anymore. I needed something better to preserve the magic of Christmas.

The goal was simple: make a convincing Santa experience that even skeptical kids couldn’t unravel. Here’s the workflow: 1. Parents fill out a simple form (child's name, age etc). 2. The backend crafts a personalized prompt for LLM and initiates a phone call. 3. The TTS model converts LLM outputs into Santa’s voice. 4. After the call parents receive an audio recording via email as a memorable keepsake.

It might not be groundbreaking AI research, but seeing my kids light up made the late nights worth it.
