We designed a sleek, modular AI shopping assistant interface with both light and dark themes, optimized for desktop and mobile experiences. The UI emphasizes clarity, ease of use, and gamified interaction to keep users engaged throughout the shopping process. We implemented a chat-based interface powered by personalized recommendations, image uploads, selectable reply options, and real-time interaction states (loading, typing, errors). The design system supports scalability via a flexible UI kit and was built with a focus on seamless integration into Shopify stores and other marketplaces.
