Stable Diffusion Prompt Generator
The Stable Diffusion Prompt Generator composes an image prompt for Stable Diffusion. Describe the subject, style, lighting, composition and mood; set an aspect ratio and negatives; and copy a prompt in Stable Diffusion's exact syntax. Everything is generated locally in your browser.
Negative prompt: low quality, blurry, distorted, watermark, text, extra limbs
A great Stable Diffusion image starts with a well-ordered description: subject first, then style, lighting, composition and mood. This generator walks you through each of those and emits a prompt in the syntax Stable Diffusion expects, so you spend less time wrestling with wording and more time iterating on the image.
How to use the Stable Diffusion Prompt Generator
- Describe the subject, then its style, medium, lighting and composition.
- Set an aspect ratio and list anything to avoid as negatives.
- Copy the prompt in Stable Diffusion's syntax straight into the tool.
Common use cases
- Generate concept art, thumbnails or hero images for a project.
- Explore a visual style quickly by varying one descriptor at a time.
- Build a repeatable Stable Diffusion prompt template for a consistent look.
Tips
- Put what you don't want in a separate negative prompt (e.g. 'blurry, extra fingers').
- Comma-separated keyword tags usually work better than full sentences.
- Name the checkpoint and sampler if you're targeting a specific pipeline.
Frequently asked questions
Is anything sent to a server? +
No. The prompt is assembled entirely in your browser from your inputs — nothing is uploaded, and no AI API is called. It is a deterministic builder, so the same inputs always produce the same prompt.
Does this generator create the image? +
No. It writes a text prompt in Stable Diffusion's syntax that you paste into Stable Diffusion to generate the image — it never renders or uploads anything.
Can I use the generated images commercially? +
That depends on Stable Diffusion's own licence, not on this tool — check Stable Diffusion's terms. The prompt itself is yours to use freely.
