Promptist

Promptist runs as a demo on Hugging Face Spaces, so you can try it in a browser without installing anything.

The demo runs on CPU, which means generation is slow.

If speed matters, load the model locally on a GPU instead.

Promptist is a prompt generator and prompt engineering tool for Stable Diffusion v1-4.

You type a plain description of the image you want, and Promptist rewrites it into a prompt the model prefers, then passes it to the text to image step.

The idea is that Stable Diffusion tends to respond better to prompts written in a particular style, and most people do not write that way by default.

Promptist does the rewriting for you.

It is built around a single model, Stable Diffusion v1-4, so it is a narrow tool rather than a general image studio.

That focus is useful if you want better results from that model without learning prompt tricks yourself.

Expect to wait on the hosted version, though.
