Make your game the one they tap
On Roblox, players decide in half a second from a thumbnail the size of a stamp. RblxThumbnail shows you how yours looks in the feed, scores it for free, then makes a better one. It makes models and sounds for your game too.
How clickable is your thumbnail?
Drop in the thumbnail or icon you're using now. You get an honest AI score for how it reads at phone size, plus 3 specific fixes.
Not just thumbnails
Everything your game's page and next update need, all in the same style and paid for with the same credits.

Questions?
Is the Thumbnail Score really free?
Yes. You get 5 a day with no account and 30 a day with a free one. It's an AI opinion on how readable and eye-catching your image is at phone size. It isn't a promise of clicks, but the fixes it suggests are the ones that usually matter.
Do the 3D models work in Roblox Studio?
Yes. You get GLB, FBX and OBJ files with textures, kept under Roblox's 10,000-triangle limit. Import them with Studio's 3D Importer (File → Import 3D).
Can I upload the sound effects to Roblox?
Yes. They're MP3s, which Roblox accepts. Upload them in the Creator Hub like any other audio.
Can I use everything commercially?
Yes. Anything you generate is yours to use in and around your games: icons, thumbnails, ads, models and sounds.
Do credits expire?
No. Credits from packs and plans stay in your account. Plans top you up with fresh credits every month.
What if a generation fails?
You get the credits back automatically. You only pay for things you actually receive.
Can I make stuff with characters from other games or shows?
No. To keep your game safe from takedowns, we block other people's characters and brands. Your own game's content is always fine.
