Get inspired
Start with a direction, not a blank canvas.
A few thumbnail patterns that work well for creator content, tool reviews, challenges, and tutorial videos. The homepage stays focused; heavier inputs live in the workbench.

Why creators use it
Small controls. Faster thumbnail decisions.
Three variants by default
Every run gives you three directions: curiosity, face focus, and bold text. It is made for quick A/B thinking.
Language-aware output
Pick the thumbnail text language separately from the interface. Useful when your channel targets another market.
Built for YouTube first
16:9 is the main format. Shorts and social sizes stay available without making the home tool feel heavy.
Pricing
Start free. Upgrade when you need clean downloads, more generations, and faster workflow.
