Thumbnail Generator

Linking your YouTube channel trains the AI on your face, your thumbnail style and your niche, so every generation looks like your channel instead of generic AI. It takes about 30 seconds, needs no uploads if your face already appears in your thumbnails, and is the single highest-impact setting

Adjust and Crop are the final polish pass. A light bump to vibrance and contrast makes the thumbnail pop at small size, and cropping dead space tightens the framing. It takes under a minute, it is the pass most creators skip, and it is what makes a thumbnail stand out in a crowded feed.

Magic Eraser removes anything from a thumbnail in one click for 2 credits and rebuilds the background behind it. Highlight loosely, erase, and work in the order that matters: remove everything you do not want first, then add and adjust what is left.

The 1of10 Thumbnail Generator is an AI tool that creates on-brand YouTube thumbnails from a title, description, sketch or reference image, then refines them in a built-in editor. Link your channel so it learns your face and style, pick a model, generate four variations, and finish with one-clic

The most powerful way to generate is a detailed prompt in four lines: the video title, the exact composition, the background and any text. Generate, spot what is wrong, add a correction line, and regenerate until it is about 90% there, then finish in the editor.

The editor's text tool adds draggable text layers with a full font library (Impact, Anton, Bebas Neue and more) plus custom font upload, stroke and shadow. The one rule that governs thumbnail typography: it has to read small. Big, bold, few words and strong contrast win the click.
