Generative AI (GenAI) presents both opportunities and challenges for product designers as they strive to create user-friendly and intuitive interfaces that connect AI's potential with user needs. Unlike deterministic actions in traditional software, GenAI interactions involve iterative and open-ended exchanges, requiring designers to enhance accuracy, establish trust, and provide clear source information to users. Despite perceptions that GenAI is complex and best suited for technical experts, advancements in product design aim to make AI assistants accessible and valuable to all users by improving ease of use and demonstrating their practical benefits in everyday tasks. As GenAI continues to evolve, designers face the challenge of balancing proactive AI assistance with user comfort, exploring new interaction modes like voice and visual analysis, and ensuring solutions remain relevant in a rapidly changing technological landscape.
