Thumbnail prompt Generator for YouTube
Get a thumbnail prompt in under a minute. Tap a few choices and copy a prompt for a cover that is easy to read even on a phone.
Thumbnails that earn the click
Most viewers pick a video by its cover. The best covers keep three things: very few words, one clear subject and bright contrast. This page turns your picks into a prompt that sets all three.
Faces get the most clicks, so you can set the look on the face too. The prompt keeps text huge and bold so it reads at tiny sizes. Paste it into any AI image tool, then upload the result to YouTube.

FAQ
Is it free?

How many words should I use?
Three or four at most. Short text reads best at small sizes.

Faces get more clicks, but you can skip that part for covers with objects only.

You can. The short cover text is built from it, not copied from it.
