Describe it, get it
Write a plain-language brief. Pick a style — hyper, cinematic, cartoon, horror — and an aspect ratio. The prompt is engineered for small-tile readability: one focal subject, hard contrast, no clutter.

Thumbnails that get the click
Describe your game, pick a model, and get a bold, readable Roblox thumbnail in seconds. Drop in a reference and say “make it like this.” Then have it reviewed before you publish.
1 credit = 1 thumbnail. Failed generations are refunded automatically.
Edit by chatting
Attach up to 10 images and talk to them: “put the character from image 1 on the left, use image 2's colours, add a zombie”. Then keep refining — every message edits the result.
“Make it like this”
Upload a thumbnail you like and choose how closely to follow it: loose inspiration, matched composition, or a near-exact layout. Your reference stays in your account.
Reviewed before you ship
Get a 0–100 click-through score with readability, contrast, focal clarity and text ratings — plus concrete fixes. Reviews are free.
Pick your model
Choose from the image models available on OpenRouter. Swap models between generations to compare results without changing anything else.

FAQ
How do credits work?
1 credit = 1 thumbnail (edits cost the same). If a generation fails, the credit is refunded automatically.
What does invite-only mean?
During beta you need an invite code to sign up. Codes come from the team or existing members.
Can it match my existing thumbnail style?
Yes — attach your old thumbnails to the message and tell the model to follow their style, layout or colours.
Which AI models are used?
Every image-capable model on OpenRouter (Gemini, GPT-image and more). Pick one, or let Auto choose per brief.
