About this prompt

What this prompt creates

This prompt creates a thumbnail built for small screens: a big, clear face on one side and a short, bold headline on the other. The yellow background and white outline separate you from everything else, so the image stays readable even as a tiny preview on a phone. The layout follows simple rules that help thumbnails get noticed without relying on clutter or clickbait graphics.

Tips for the best result

  • Use a photo with a strong expression; the thumbnail style exaggerates emotion, so a neutral face looks flat.
  • Keep the headline to five words or fewer and check that it matches your video honestly.
  • Preview the result at a small size before publishing to make sure the text is still readable.
  • Create two or three versions with different background colours and headline wording, then compare them side by side to see which one is easiest to read at a glance.

Variations to try

  • Change the background colour to match your channel's brand colour.
  • Add a small object next to you that shows the topic, such as a book or a camera.
  • Ask for a split before/after layout for transformation videos.
