Sketch out thumbnail directions before you open your editor
Type in your video topic and get concept briefs — palette, layout, and emotion — built to help your thumbnail earn the click.
Palette layer
A color direction with the reasoning behind it, not just a swatch
Layout layer
Where the subject and text overlay sit inside the frame
Emotion layer
The expression that signals what the video feels like

InstantEnter a topic and click Render concepts to fill the canvas.
Design principles behind every concept
A thumbnail has less than a second to earn a click. Every concept generated here is built around:
- High contrast so it stands out in a crowded feed
- One clear focal point, not five competing elements
- An emotional expression that signals what the video feels like
Use each concept as a brief for yourself, an editor, or a designer — the mock frame shows where things go, not a finished design.
