What's new in YouThumb: a redesigned generation page
A good thumbnail rarely comes from a single attempt. You start with a vague idea, test, compare, try again. The new YouThumb is built for that back-and-forth: everything happens on one page, and every attempt feeds the next one.A redesigned generation page
The composer sits on top: source thumbnail, prompt, options, number of variations, Generate. Every attempt stays listed below, each with its own prompt. Like a result? Use as source and it becomes the starting point for the next one. More in "A new page to generate your thumbnails".A YouTube link and your images
Paste a video link: YouThumb fetches its thumbnail and uses it as the source. Then add your logos, screenshots or photos: they become@image1, @image2, which you place in the prompt. See "Start from a YouTube video and your own images".
The composition sketch
Draw where the title, the logo and your face go: a few rectangles, a circle, an arrow. The AI follows the layout. See "The composition sketch".A better prompt in one click
Improve the prompt turns a vague line into a real brief, and Reuse this run reloads a whole past attempt into the composer. See "Improve your thumbnail prompt in one click".Compare variations
Tick two or three variations, click Compare: they show up side by side, at the same scale. Keep the best one as a favorite. See "Compare thumbnail variations side by side".All of these features are already live on the generation page of every project.
