How We Built an AI Santa That Scales Holiday Greetings

This year at Keyrus, we didn't just send holiday cards. We built an AI-powered Santa Claus that generates fully personalised video greetings in real-time.

Why? Because we believe the best way to explain "AI-Powered Growth" is to show, not tell.

We Didn't Just Want to Say "Merry Christmas." We Wanted to Scale It

In growth marketing, personalisation is everything. But here's the problem every marketer faces: how do you deliver genuinely personalised experiences to thousands of people without your team working 24/7

Our answer: build an engine that does it for you.

So we hired the ultimate seasonal worker, an AI Santa, to demonstrate what's possible when you combine generative Artificial Intelligence, data, and automation.

Want to see AI Santa in action? Create your own custom Santa video in seconds now.

The Technology: Where Data Meets Magic

We built a platform that combines three generative Artificial Intelligence technologies into a seamless personalization engine:

  • AI Text Generation creates dynamic, personalised scripts tailored to each recipient

  • AI Audio Synthesis delivers Santa's voice with natural intonation and warmth

  • AI Video Generation brings it all together in a cohesive, believable video

The workflow is simple but powerful:

  • Data Ingestion

    : Users input recipient details and their "Naughty or Nice" status

  • GenAI Processing

    : Our engine synthesises text, audio, and video in real-time

  • Hyper-Personalization

    : A unique 1:1 video greeting is generated instantly

Each video is unique, adapting to the recipient's name, custom messages, and context. Demonstrating how Artificial Intelligence can deliver true personalisation at unlimited scale.

This Isn't Just a Holiday Card. It's a Live Demo

While the AI Santa is a fun holiday experience, the underlying technology has serious business applications. The same principles we used to personalise Santa videos can transform customer journeys across industries.

If we can do this for holiday greetings, imagine what we can do for your customer engagement strategy.

We didn't want to create just another AI demo. We wanted something people would genuinely enjoy using and sharing. That's why we made the generator publicly available. Anyone can create their own AI Santa video for team members, clients, family, or friends.

Experience It Yourself

The best way to understand what AI-powered personalisation feels like is to create one yourself.

Input a name, add a custom message, decide if your recipient has been naughty or nice, and watch as Artificial Intelligence generates a unique video in real-time. Send it to a colleague, share it with a client, or surprise a friend.
