Tips for Best Results

  • 💡Keep onboarding headlines short; image models often struggle with long interface text.
  • 💡Specify whether you want a sequence of screens or a single screen, because composition changes dramatically.
  • 💡Use Ideogram or DALL-E 3 when readable UI copy matters more than painterly style.
  • 💡Ask for a post-generation QA checklist so you can reject mockups with impossible spacing or fake controls.
