Key challenges
Conversations needed to stay on script, safe, and age-appropriate while maintaining an engaging and immersive Santa persona.
The AI had to recognise and respond sensitively to unexpected or emotional topics raised by children (e.g., loss of a loved one).
Santa’s needed to feel authentic, warm, and magical, avoiding unnatural AI responses.
The AI needed to handle high call volumes, especially during peak holiday periods.
