Features
Generation, a saved visual identity, an editor, and a history library. Nothing we have not shipped.
Describe the scene, pick Roblox, Minecraft, Fortnite, or YouTube, and get a 16:9 thumbnail ready to ship.
Save colors, references, and notes once. Every later render stays on-brand.
Drop a screenshot of your game. The model reads the look instead of guessing.
Add text, arrows, and shapes on the result without leaving Spantly.
Free starts at 720p. Paid plans unlock 1080p, 2K, and 4K.
Every generation stays in your library so you can download, edit, or share.
Flow
Type the concept, keep the game on-brand, ship the 16:9 thumbnail. That is the whole loop.
One line is enough. No brief, no files, no designer wait.
Colors, notes, and a reference stay with the game so the next render matches.
Edit labels if you need them, then download or share. One thumbnail spent.
Why it matters
On Roblox, the thumbnail decides whether your game gets opened or scrolled past. These features exist so you can iterate in minutes.
