Thumbmachine

Thumbmachine is an AI platform for making YouTube video thumbnails. A user picks a hero image, either generated by the AI or taken from their own photos, then chooses a background from the site's collection, an uploaded image or a gradient, selects colors and enters a title. The tool assembles the thumbnail, and users can switch styles, cycle through variations and adjust colors until they are satisfied. The vendor lists several supporting features: image generation using Stability visual AI, access to more than 3 million free photos, a background remover, image upscaling and unlimited variations. It also promotes creating multiple versions of a thumbnail so creators can run A/B tests to improve click through rates. It is meant for YouTube creators and anyone producing visual headers for videos, articles or social posts who does not want to design from scratch. Signup is free and requires no credit card. A Premium package is mentioned in the site's FAQ, which states that the $1 thumbnails included in it have the same resolution and no other limits compared with the others. The vendor does not publish full plan prices.
