How it works
- Describe the image. Type a clear prompt — subject, setting, mood, and any style.
- Pick model + size (optional). Use Advanced options for a fast vs detailed model and an aspect ratio.
- Generate. Your request runs (queuing if the servers are busy) and the image appears to download.
About this tool
Describe a picture and the model paints it — a scene, a character, an icon, a piece of concept art. Write what you want in plain words, optionally nudge the look with a style word, and the image appears for you to download. Two models are on tap: a fast one for quick ideas and a more detailed one when you want to slow down and get it right. Because image generation runs a large model on a GPU, busy periods put your request in a short queue; it then runs and the result shows up here. Nothing is stored.
What people use it for
- Create concept art or an illustration from an idea
- Generate a unique image for a post, slide or thumbnail
- Make an icon, mascot or simple logo starting point
- Visualise a scene or character described in words
Frequently asked questions
Be specific about the subject, setting and mood, and add a style word or two ("watercolour", "3d render", "photo"). Short vague prompts give generic results; a sentence or two works best.
One is tuned for speed — great for quickly trying ideas — and the other for detail, which takes a little longer but renders more carefully. Switch between them in Advanced options.
Image generation runs a large model on a shared GPU. When several people request at once, jobs are served in order so none fail; you keep your place and the image appears when your turn comes. Pro accounts are served first.
Yes — pick an aspect ratio (square, landscape or portrait) in Advanced options to match where you’ll use it.
The models used are open and permissively licensed, but you are responsible for how you use a generated image; avoid prompts that copy a living artist’s style or a trademark.
No. The prompt is used only to generate the image, which is handed to you and not kept on a server.
