What Thumbnailr.io is
Thumbnailr.io is a web-based AI generator for YouTube thumbnails. It can create a thumbnail from a written brief, a reference image, or a YouTube link, then export the result as a 1280×720 PNG without a watermark. The site says a typical run takes about a minute. Users can provide up to three reference images or a YouTube thumbnail link to guide the style, and add up to three images of faces, products, or shots as the main subject. An edit prompt generates another version from the same project, using one credit per edit. A beta script-generation tool shares the thumbnail credit balance and also uses one credit for each generate, regenerate, or edit. New accounts receive five free credits without a credit card, and those credits never expire. Thumbnailr lists a Free plan at no cost. Its one-time Credit pack is listed at $1,025, paid once for 25 credits that do not expire. The page does not list a free trial or integrations beyond using a YouTube link as input.
