Stable Diffusion web UI

A web page on your own computer for making and editing AI images with Stable Diffusion.

Widely used

What it does

Stable Diffusion is an AI model that makes pictures from a written description. This project wraps it in a web page that runs on your own computer, so you can type a prompt and get images without writing code.

Beyond text-to-image, it can change an existing picture, fill in or extend parts of an image, fix faces and make small images bigger. You can also list things you don't want to see, save favourite prompt styles and run large batches.

A big library of community extensions adds more features. The settings used for each image are saved with it, so you can recreate a result later.

Who it's for

Artists, hobbyists and anyone who wants to make AI images on their own machine with lots of control.

Can I use it without coding?

With some setup. Windows users can download a package and run a couple of files; other setups need Python and Git. A capable graphics card helps a lot. New to this? Start here.
