Generate for the format

Social content works best when the prompt includes the target surface and crop from the beginning.

  • 9:16 vertical scenes for stories and short video covers
  • 16:9 thumbnails with clear focal point and text area
  • 1:1 posts with high contrast and strong subject separation

Keep a repeatable brand system

Use recurring colors, props, backgrounds, and lighting so every generated image feels like part of the same creator brand.

  • Define a small color palette
  • Reuse a background or scene motif
  • Save the prompt fragments that perform well

Frequently asked questions

Can I create YouTube thumbnails with AI?

Yes. Use a 16:9 aspect ratio, describe the focal subject clearly, and reserve space for short headline text.

What makes an AI social visual perform better?

Strong contrast, a single clear subject, recognizable brand color, and a prompt designed for the final platform all help.
