ThumbleStudio builds YouTube thumbnails that look handcrafted.
Search YouTube, pick a video, upload a face, and generate a new thumbnail. Built for fast market validation and sharp client demos.
How the thumbnail flow works
We mirror the real YouTube journey: search, pick a result, upload a face, and generate the final cover.
Type a query
Any niche, any topic, any keyword set.
Pick the video
We pull the thumbnail and show a download animation.
Upload a face
Drop a photo of the creator or the main character.
Get the result
Soft blur reveal, then a crisp final thumbnail.
Before and after in one pass
Compare the original thumbnail from YouTube with the generated result. This is the exact flow used in the demo video.
- Original thumbnail from search
- Upload a face or avatar
- Final AI-generated cover
