What it does

Thumbo makes YouTube thumbnails with AI. The creator uploads three photos once, and generated thumbnails keep that face recognizable. A channel link can be pasted so the output follows that channel style, or one of 50+ style packs can be picked instead. Finished thumbnails are edited by typing instructions, such as a bigger face or a different title. The site also has a free channel audit and free tools that need no signup: a thumbnail downloader, a resizer, a compressor to 2MB, a font previewer and a thumbnail previewer. A free Chrome extension, Thumbo Lens, is available as well.
