THUMBNAIL
Design click-worthy YouTube thumbnails
Most AI thumbnail makers go straight from a prompt to an image. This one plans first: give it your title and it returns four different concepts — four genuinely different arguments for why someone should click — and only then renders the one you choose at full YouTube resolution.
That order matters because a thumbnail is a strategic decision wearing a visual costume. The image is downstream of the idea, and four ideas to choose between is worth more than four variations on the same idea.
Every concept comes with the reasoning attached: what it is promising, what tension it sets up, and why it would out-perform the obvious version. You can disagree with it, which is the point.
● HOW IT WORKS
Give a video title and niche
Pick from four concepts
Render the image and download it
Runs on credits. Every account starts with a free balance, and you only spend on a generation that succeeds.
The four concepts deliberately pull in different directions. One might lead with a face and an emotion, one with a before-and-after, one with a single object photographed as a question, one with text doing the work. They are alternatives, not renders of the same sketch.
You pick one, and only that one gets generated. Reading four ideas costs nothing; rendering four images would.
A thumbnail that repeats the title wastes half the click. If the title says the mistake cost forty thousand dollars, the thumbnail should not say forty thousand dollars — it should show the thing that cost it. The two elements are meant to be two halves of one sentence, and that principle is built into how the concepts are proposed.
So the title is a required input, not an optional one. The concepts are generated against it, and a thumbnail generated without knowing the title is a thumbnail guessing at half the job.
Output is 16:9 at YouTube's recommended dimensions, which means no cropping surprise when you upload it and no soft edges when it is scaled down.
It is also worth previewing at the size it will really be seen. Most impressions are a small rectangle in a suggested column on a phone, not the large preview in Studio. A concept that only works at full size is a concept that does not work.
Then skip the step. Inside a project the thumbnail stage can be marked as done with your own image, and the flow moves on to titles, descriptions and tags without asking again.
The pipeline is meant to be usable in pieces. Nothing forces you to generate a stage you have already handled yourself.
● QUESTIONS
16:9 at YouTube's recommended 1280x720, which is the resolution Studio expects and the one that scales down cleanly to the small sizes most impressions actually appear at.
The generator produces the image from a text concept, so it does not composite your photo in. The common workflow is to generate the background and composition here and drop your own cut-out on top afterwards.
Because choosing between four strategies is the decision that changes the click-through rate, and rendering four images to find that out would cost four times as much for no extra information.
The concepts are part of the generation and the cost is shown before you run it. If the image generation fails you are not charged — credits are deducted only after an image comes back.
Yes. Pick a different concept, or adjust the title and run it again. Each render is a separate generation, so a second attempt costs the same as the first.
It generates 16:9 images for long-form YouTube. Shorts use a frame from the video itself rather than an uploaded thumbnail, so there is nothing to generate for them.
