Introduction.

Introduction.

The AI Assistant for Children is an iOS mobile app designed to help kids and teenagers with daily tasks like homework, stress management, and planning their day through fun and emotional interaction. Unlike traditional assistants, this app uses animal avatars (teal cat, pink rabbit, green dog, etc.) to create a more engaging and personalized experience.

Challenge.

Challenge.

Designing for kids presented challenges such as keeping the interface simple and engaging, while also catering to their emotional needs. Children require intuitive design with visual appeal, but they also need trust and ease of navigation to stay engaged without frustration.

Solution.

Solution.

To address these challenges, we crafted a design that focused on creating a seamless user experience, while giving special attention to the emotional connection between the user and the AI assistant. The app’s UI features colorful, lovable avatars that children can select based on their personal preferences, giving them a sense of ownership and individuality. The UX journey was carefully planned to guide the user effortlessly through tasks while maintaining an emotional layer—whether the AI is helping with homework, providing stress relief tips, or telling a joke, the interaction is always friendly, encouraging, and supportive.


We prioritized designing clear and simple UX flows, with intuitive navigation and bite-sized tasks that align with the attention spans of kids. The option for users to mark their favorite tasks was introduced to make the experience more personalized, allowing them to quickly access the features they love most. By creating a playful yet functional environment, the app helps children form a genuine bond with their chosen character, ensuring the experience feels more like a conversation with a friend rather than an impersonal tool.
