AI Thumbnails

The generator produces four thumbnails per generation, for the cost of one, so you can pick the most clickable rather than betting on a single idea. Read the batch with four checks (does it read small, is the emotion strong, does it create curiosity, does it stand out), then test your top two.

Download a thumbnail at standard resolution, or upscale to a sharper 4K file for 1 credit. The upscaler works so well it doubles as a repair tool: upload an old low-resolution thumbnail, edit it and upscale it to bring an old video's thumbnail up to current quality.

Draw a rough layout in the tool's canvas or upload a sketch, add a short line of context naming the shapes, and the AI turns it into a finished thumbnail that follows your composition. The sketch does not need to be good; a stick figure is enough, because the tool reads layout, not artistry.

Gen-2 (20 credits) is best for face consistency and photoreal entertainment thumbnails; Gen-2.5 (16 credits) is faster, cheaper and better for graphics and charts. There is no universal winner, so run the same prompt through both models once and keep whichever fits your channel.

Magic Edit changes one region of a thumbnail into something you describe, for 2 credits, leaving everything else untouched. Highlight the area, type what it should become and generate. It is the tool for an almost-perfect thumbnail with one wrong detail, with no risk to the parts that already w

Face Swap detects the face in a finished thumbnail and maps your real likeness onto it from up to two reference shots, for 4 credits and no prompt. Match the reference angle and expression to the shot for a clean result, and use it to fix an off face or add a face to a scene that lacks one.

Under the plus icon you can feed the tool a reference image to recreate a real object, a background, your face (two shots from different angles) or a sketch. A prompt tells the tool the idea; these inputs show it the specifics that words struggle with.

Landscape thumbnails win the long-form feeds; vertical Shorts thumbnails win the Shorts tab, search and suggested placements where a Short is shown as a still. The 1of10 generator builds both from one engine with a single format switch, so you compose for the surface, not the tool.

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.
