What YouTube Thumbnails makes
This skill creates YouTube thumbnails and vertical video covers. It builds a truthful concept from your video's topic, keeps the faces of up to three people you give it, adds logos if you want, and makes the main image with the Nano Banana Pro image model. It then makes small, focused edits.
It uses the Higgsfield command line tool, so you need to install it and log in to a Higgsfield account. The default shape is 16:9 for YouTube, with 9:16 for Shorts and 4:5 for Instagram. It never invents claims about the video. Text is optional and added as a clean overlay.
Best for: YouTubers and small channels who want thumbnails without a designer.
- Truth-first concepts, no made-up claims
- Keeps up to three real faces from your photos
- Optional logo, flat or 3D
- Ratios: 16:9, 9:16 and 4:5
- Variants and small edits on request
Example prompts
Type something like this once the skill is added. Your app opens the skill when the request matches.
