Free. No card, no trial, no credits.
Make 10 thumbnails. Or 10,000. Free.
No credits. No packs. No running out at 2am the night before you ship. Describe your game in plain English and get back a finished thumbnail or icon, built for the Discover grid it has to survive.
You connect your own Google or OpenAI key, and they bill you directly for the images at cost, usually pennies each. We take nothing, which is how free stays free.
Examples of generated stuff.
Every one came out of a single prompt with no touch-ups. The games are invented, in the formats blowing up on Roblox right now, because putting a real game here would imply its developer uses us.

Thumbnails you can make
Built for one game, on one platform.
Not a general image tool with a Roblox preset bolted on the side.
It gets better from real click rates.
Once your thumbnail has been live a few days, you can send a screenshot of your own analytics. A person reads every one, and the ones that check out become the evidence the art direction gets tuned against.
So what steers your next thumbnail is what got clicked on Roblox, not what a model happens to remember about Roblox from a year ago.
Sharing is optional and takes about thirty seconds.
One change means one change
Ask for the character to look scared and the rest of the frame holds still. No rerolling into a brand new scene.
Thumbnails and icons both
1024×576 for the Discover tile, 512×512 for the square badge. Different art direction for each, because they are not crops of each other.
Bring your own screenshots
Drop in your actual character or map and it works those into the shot instead of inventing something close.
It knows what Roblox looks like
Characters come out as actual Roblox avatars, not generic blocky figures, with lighting and framing that suit the genre you asked for.
Type a sentence. Get a thumbnail.
No prompt tricks, no negative prompts, no seed numbers to memorise. Four steps, and you only ever do the first one.
Say it in plain English
“Obby with lava and a bacon hair guy mid jump.” That is the whole skill.
Wide or square
The Discover tile and the game icon get different framing, not the same picture cropped.
It art directs for you
Roblox-specific direction goes in before your words do: how a character is built, how a scene is lit, how much frame the subject takes.
Change one thing
Ask for the character to look scared and only that changes. The rest holds still.
Questions people actually ask
It is actually free? What is the catch?
It is free, and the catch is that you bring your own model key. The expensive part is the image generation itself, and that runs on your Google or OpenAI key so they bill you directly, usually a few pence an image. We are not paying for your pictures, which is exactly why we have no reason to ration them or charge you.
Will it stay free?
It is free while we are building an audience, and there is no plan to change that soon. If a paid tier ever appears it will be announced properly, not switched on quietly, and anything you have already made stays yours.
What will the model provider charge me?
Google is roughly $0.13 an image, OpenAI roughly $0.17. Fifty thumbnails a month is about $7 on their bill and nothing on ours. Every competitor pays that same cost, they just bake it into a $65 tier and keep the difference.
What happens to the analytics screenshot I share?
A person looks at it and checks it against the numbers you typed, then approves or rejects it. Approved ones inform how the art direction gets tuned. It is never published, never attached to your game anywhere public, and sharing is entirely optional. Crop out anything you would rather we did not see.
How hard is the Google key setup?
A couple of minutes. You make a key in Google AI Studio or on the OpenAI platform and turn on billing for it. We check the key by generating one real test image before we save it, so you find out during setup instead of on your first prompt.
Do I own what it makes?
Yes, and you can use it commercially. Worth knowing that no generative model guarantees originality, so check anything before you publish it.
Are you affiliated with Roblox?
No. Not affiliated, endorsed or sponsored. Roblox is their trademark and you are still responsible for following their rules on anything you upload.
