AI Thumbnail Maker
Describe the thumbnail. Get the thumbnail.
AI Thumbnail Maker generates video thumbnail images from a written prompt and the reference images you supply, so you can produce a cover for the next upload without opening an editor.
Video creators, streamers and anyone who ships a thumbnail with every upload.
Get the app. Coming soon to the App Store and Google Play.
What it does
Prompt in, thumbnail out
Write what the thumbnail should show and the app generates it as a finished image.
Bring your own references
Add reference images — your face, your product, a frame from the video — and they feed into the result.
Iterate quickly
Regenerate with a changed prompt until one of the options is the one you want to publish.
Download and upload
Export the image you picked and put it straight on the video.
How it works
- Write a prompt describing the thumbnail you want.
- Add any reference images you want the result to draw on.
- Generate, compare and refine the prompt.
- Download the thumbnail you picked.
Thumbnails are produced by an image model. Any text rendered inside a generated image can be misspelled or wrong, and likenesses, logos and products can be reproduced inaccurately. Review a thumbnail before you publish it, and only upload reference images you have the right to use.
Common questions
Do I need design skills?
No. You describe the thumbnail in words and add references if you have them.
Will any text on the image be spelled correctly?
Not necessarily. Text inside a generated image is drawn by an image model and can come out misspelled or garbled. Check any wording before you publish the thumbnail.
Can I use the thumbnails commercially?
You keep the rights to the images you upload and to the thumbnails the app generates for you. You are responsible for having the rights to whatever you upload as a reference.
