The generator produces four thumbnails per generation, for the cost of one, so you can pick the most clickable rather than betting on a single idea. Read the batch with four checks (does it read small, is the emotion strong, does it create curiosity, does it stand out), then test your top two.

Download a thumbnail at standard resolution, or upscale to a sharper 4K file for 1 credit. The upscaler works so well it doubles as a repair tool: upload an old low-resolution thumbnail, edit it and upscale it to bring an old video's thumbnail up to current quality.
