Nicer Visuals
Part of a good UX is also an appealing visual design. Similarly to getting a better UX, you can also remind the AI of some of the sound guidlines of visual design. For example:
Please consider the following guidelines for visual design, when creating the product:
Pick and use a consistent color palette. Keep in mind users suffering from colorblindness and assure sufficient contrast in picking colors.
Pick and use fonts, font weights and font sizes that match the tone of voice and the type of product, as well as support readability.
Use images, visuals and illustrations to break up text, and use white space to underline hierarchy, help grouping and create balance.
Create a coherent layout emphasizing the structure and hierarchy of the product, including Z patterns and F patterns. Consider using a grid if it makes sense for the product.
