Design

Opportunity

Children learn best when they connect with a character. We partnered with The Little Labs to design a friendly elephant who guides each activity and appears across our stories. The character greets kids, models tasks with simple cues, and celebrates progress with animations and audio. Consistent personality, voice, and pacing help build trust, so practice feels like a narrative that kids can follow and enjoy.

Design System

Design System

Petar’s design system was created to support emotional presence, reduce cognitive load, and maintain visual consistency across interactions.

Rather than drawing attention to the interface itself, the system is designed to quietly support moments of comfort, connection, and play.

Information Architecture

Information Architecture

Petar’s information architecture was designed to support emotional continuity rather than task completion.

Instead of overwhelming users with dense menus or rigid hierarchies, the experience is organized into clear, lightweight sections that mirror how users naturally engage with companionship.

This project taught me how small interaction decisions significantly impact emotional engagement, and how UX design in AI-driven products requires balancing system logic with human perception.
