SwiftThumbnail

SwiftThumbnail とは？

SwiftThumbnail helps YouTube creators design better covers by generating multiple thumbnail variations at once. Instead of editing manually, users input a style or concept to produce up to ten design branches. Creators can swap backgrounds, test text layouts, and compare different styling paths side-by-side to pick their favorite. The platform also includes team workspaces, shared credit pools, and brand color presets to speed up creative iteration.
