Frequently asked questions

Is the Stable Diffusion prompt generator free?

Yes, you can generate Stable Diffusion prompts for free. Pro adds the flagship model, the Optimizer and your saved library.

Does it create a negative prompt too?

Yes. Alongside the main prompt it produces a matching negative prompt to keep out common artifacts like extra fingers, blur or watermarks, which is key to clean Stable Diffusion results.

Which Stable Diffusion versions does it support?

The prompts use the comma-separated tag style that works across SD 1.5, SDXL and most forks, and run in Automatic1111, ComfyUI and similar tools. You can adjust token weights after pasting.
