Prompt Quality Tips

  • Be specific: "a golden retriever running on a beach at sunset" beats "a dog outside"
  • Add lighting details — it dramatically changes the mood
  • Reference art styles or artists for consistent aesthetics
  • Negative prompts (Stable Diffusion) prevent common artifacts
  • Aspect ratio matters: 16:9 for landscape, 9:16 for portrait, 1:1 for social media
  • Use quality modifiers: "8K", "ultra-detailed", "masterpiece" improve output

Describe your image subject and click Generate to get prompts for all 4 AI art platforms.
