Make the visuals that get the click — thumbnails, covers, posts, pins & carousels. Describe it, pick a style, done in about a minute. No subscription, start free.
Stop staring at a blank prompt box. Thumby is the thumbnail app that does the design thinking for you.
Tell it your video idea in one line. Pick a style modeled on a top creator in your niche. In seconds you get a finished, click-worthy thumbnail — already shaped by the rules that actually move click-through in 2026.
WHY CREATORS SWITCH TO THUMBY
Built on what works in your niche
Most tools hand you a blank canvas or a blank prompt. Thumby starts from a curated library of looks reverse-engineered from the creators who already win the click — gaming, kids, food, tech, vlog, finance, true-crime and more. You're not guessing what a good thumbnail looks like. You're starting from one.
Match a top creator's style in one tap
Pick a niche style and Thumby applies its whole visual recipe — composition, contrast, lighting, framing. No prompt engineering, no design degree. Tap, describe, done.
One brief, every format
The same idea becomes a YouTube thumbnail, an Instagram post, a story, a Pinterest pin, even a full carousel — sized and styled for each surface. Make once, post everywhere.
Your face, every style
Add a photo and Thumby keeps your face consistent across every thumbnail and style, so your channel looks like you.
CTR rules baked in
Every result follows current best practice — one clear focal subject, bold readable text, mobile-first contrast — so even your first thumbnail comes out tuned to get clicks.
No subscription, ever
Pay per credit, not per month. Credits never expire. Start with 3 free on signup — no card required. Keep what you make: every output is yours, commercial use included.
