This article breaks down eight core visual design principles—contrast, hierarchy, alignment, proximity, repetition, balance, white space, and unity—and shows how to apply them when using AI to build apps. It uses before-and-after examples to illustrate how guided feedback can turn generic AI outputs into polished, cohesive interfaces.

The author explores the concept of "vibe coding," where non-coders use AI tools like Bolt to create applications with minimal technical knowledge. While the process seems accessible and fun, the resulting applications often lack depth and robustness, raising questions about their real-world effectiveness. The journey illustrates both the potential and limitations of such tools in empowering non-technical users.
