The thumbnail is the single biggest lever on your views, and yet most creators throw one together in a rush or wrestle design tools they don’t know. A cluttered, low-contrast thumbnail loses to a competitor’s even when your content is better. The click happens — or doesn’t — before anyone sees the video.
The exact thing you needed, made for you.
Iris generates high-impact YouTube thumbnail designs tailored to your video: bold focal imagery, punchy short text that reads at a glance, strong contrast and color for the feed, and composition tuned for both desktop and mobile. You describe the video and the vibe; Iris produces thumbnail concepts you can use or refine.

One prompt. A real deliverable. Not a template you fight with.
Most “free tools” hand you a rigid template and leave the hard part to you. Iris is a full autonomous agent: it does the thinking, writing, and designing, then opens the result in a live workspace where you refine it in plain English. On-brand visuals, thumbnails and creatives generated in seconds.
Actually made for you
Original, specific output built from your details — never generic fill-in-the-blanks.
Editable in plain English
Don’t like a part? Just say so. Iris rewrites, restyles, and restructures on request.
Yours to export
Take it with you — export, publish, or drop it into the tools you already use.
