Can AI generate a UI design?

AI can generate convincing screen concepts and mockups that help you explore visual directions quickly. The output is an image, not editable layers, so use it as a reference and rebuild the final design in your design tool.

Which AI is best for app mockups?

GPT Image 2.5 is the best start for flat app screens with readable labels. For a phone or laptop mockup in a realistic scene, try Gemini 3 Pro Image.

How do I get readable text in a UI image?

Keep labels short, put each one in quotation marks, and limit the screen to the elements that matter. Fewer, larger labels render more reliably than dense tables.

Tips for better results

Describe the screen top to bottom: header, main content, sidebar, footer, with the key labels in quotation marks.
Name the platform and density, for example "iOS app, 390px wide, generous spacing" or "desktop analytics dashboard".
Ask for a flat, front-on screenshot when you want a usable reference, and a device mockup only for presentation images.
Treat results as concepts: rebuild the chosen direction in your design tool rather than shipping the image.
