aiRoblox — Icons, thumbnails, and Roblox economy with AI · Icons, thumbnails and Robux for Roblox creators
For the creator who publishes experiences and sells on the Marketplace: generate the 512×512 icon and the 1920×1080 thumbnails with crisp text —because the AI doesn't write the text, it's composited afterwards—, check how your icon will look at 64 pixels in the mobile feed and calculate what you'll actually take home with the current DevEx rates and commissions.
Your experience isn't getting clicks and you don't know how many Robux you actually have left after commissions?
On the Roblox front page, the click is decided by the icon, and on mobile —where most of the traffic comes from— it renders at around 64 pixels: what looks spectacular on desktop is a blur there. aiRoblox generates the art with AI, overlays the text afterwards programmatically so it comes out crisp and typo-free, and shows you your icon genuinely shrunk to 64 pixels next to other cards, with a legibility verdict measured pixel by pixel. And on the money side: the three DevEx rates, the four sale types with their real commission —a Game Pass leaves you 70%, an Avatar Marketplace item 30%— and the split among your team, with the date each figure was verified in plain sight.

What comes out of here gets uploaded to Roblox as-is
Three things that don't usually go together: AI-generated art, typography that doesn't break and numbers that add up with today's rates.
Icons, thumbnails and badges with text you can actually read
512Ă—512 icon, 1920Ă—1080 thumbnails and 512Ă—512 badge and game pass icons. Choose from 7 genres, 5 palettes and 5 type styles, and you can upload up to 2 screenshots of your game as style reference. The AI only paints the background: your title is composited afterwards as a vector on a gradient plate, so it never comes out with warped letters or spelling mistakes. On badges and passes, what matters stays inside the safe circle and you see it already masked before downloading the square Roblox asks for.
The 64-pixel test and 5 hooks for A/B testing
Roblox lets you A/B test thumbnails, but not the game icon: here you see yours genuinely shrunk to 64 pixels, dropped into a discovery grid next to other cards, plus a verdict with four measured metrics —overall contrast, figure against background, detail density and actual text height—, not an opaque AI score. For thumbnails you request 1, 3 or 5 variants and each one pushes a different hook: epic action, mystery, reward, hero or novelty, labelled with its hypothesis so you know what you're testing when you look at the results.
DevEx, commissions and splits with verified rates
Two-way converter —from Robux to your currency and from your currency to Robux— with the three current DevEx rates, the 30,000 Robux minimum and real European Central Bank exchange rates across 30 currencies. The commission isn't 30% for everything: the calculator asks what you're selling (Game Pass, Avatar Marketplace item, in-experience item or limited resale) and it also works in reverse, telling you what price to publish at to receive an exact net amount. And the simulator splits revenue among your team with 100% adjustment and without losing a single Robux along the way.
From your game's name to uploaded files
Tell us what your game is about
Type the name, pick the genre and, if you want, the palette and up to two reference screenshots. No need to write prompts: the server does that for you.
Pick a format and generate
Icon, thumbnails or badge, with your headline text and the type style you prefer. Each format is generated at its native size; a square is never stretched to 16:9.
Check, download and do the math
Look at the legibility verdict and the mobile feed test, download piece by piece or the ZIP pack with a README that says where each file goes, and hop over to the calculator to see what you'll earn.
What Roblox creators say
“I swapped my icon for one from here and the CTR went up enough to show on the graph. What convinced me was the 64-pixel test: the one I had was gorgeous on PC and on mobile you couldn't make out a thing.”
“I started pricing with the reverse calculator and found out I'd been rounding wrong for months. Having it ask what you're selling before applying the commission, instead of slapping 30% on everything, is the difference.”
“The variants with different hooks save us the usual argument: we upload three to the panel experiment and stop deciding by gut feeling. And we paste the team split straight into Discord.”
