Is the thumbnail idea generator free?

Yes — generate thumbnail concepts free, no signup or credit card. It's powered by the same AI inside Nova.

Does it create the image?

It generates the concepts — the punchy overlay text plus a description of the visual, expression, and composition — so you can shoot or design the thumbnail fast. It doesn't render the final image.

What makes a thumbnail get clicks?

High contrast, one clear focal subject, a readable 2-4 word text overlay, and a strong emotion or curiosity gap. The viewer should grasp it in a fraction of a second on a small screen.

Can Nova make thumbnails for my clips?

Nova auto-picks a strong thumbnail frame (face-scored) for every clip it cuts from your long videos, and writes the title, description, and hashtags too. Try it free.
