You’ve probably seen the post going viral about making YouTube thumbnails with AI in one prompt. That’s us. We’re the tool behind it. A message from our founder, and YouTuber (140K)

your old videos aren't dead, they're just badly dressed. swap the thumbnail before you mourn the upload

crop tighter than feels polite. nobody ever clicked a thumbnail because they could see your shoes

if your thumbnail text just repeats your title, one of them is unemployed. make them a duo, not an echo

a neutral face is a spoiler. it tells everyone exactly how little happens in the video

a thumbnail isn't a summary, it's a single reason to click. pick one idea and make it loud, the rest is clutter

a red circle around something boring doesn't make it interesting, it just frames the disappointment

eyes are arrows. wherever your face looks in the thumbnail, the viewer looks next. stop pointing at nothing

an overpromising thumbnail buys you one click and sells your next ten. viewers forgive boring, they remember lying

don't ask friends if they like your thumbnail. ask what they think the video is about. wrong guesses are the real review

a frame grab isn't a thumbnail, it's a random employee promoted to the storefront without an interview

make the thumbnail before you film. if the idea can't be packaged, it can't be saved in the edit either

check your thumbnail in dark mode. that dramatic black background just became part of the app

your bottom right corner was never yours. the timestamp lives there, stop decorating its room

your thumbnail will spend its whole life the size of a cracker. if it only works full screen, it doesn't work

your thumbnail never appears alone. it's in a lineup with eleven rivals, so design for the comparison, not the canvas

your subscribers would click a gray square. design the thumbnail for the stranger scrolling past at full speed

a flopped video isn't dead, it's wearing the wrong outfit. swap the thumbnail and give it a second premiere

a beautiful thumbnail that raises no question is just wallpaper. curiosity gets the click, pretty gets a compliment

if your thumbnail and title say the same thing, one of them is unemployed

your logo in the corner isn't branding, it's a signature on a painting nobody bought yet
