In their own words
Thumbsmith
Thumbsmith is a web-based AI tool for creating YouTube thumbnails. A one-line idea produces four options, and its editor supports bold text, background removal, logo layers, and a 1280×720 composition. You can also make thumbnails without AI, starting from a ready-made recipe or your own background image and adding text and photos manually. Recipes provide a background, a subject slot, and styled text. Finished work can be rendered in high quality and exported at 1280×720. Logos can be added as layers on any plan; Studio can automatically place a saved logo on each render and create batches for up to 10 video titles at once. The Free plan costs nothing and includes three starter HQ credits, daily watermarked four-option previews, and 10 background removals per day. Pro costs $5 a month and lists 80 HQ generations per month. Studio costs $19 a month and lists 400 monthly generations. A separate credit top-up costs $15, paid once for 200 credits. The site describes YouTube-ready exports but does not list a direct YouTube integration.
