Promptist

Typing a short description into Stable Diffusion and getting something vaguely close to what you pictured is frustrating when you know the model is capable of more. Promptist is a prompt interface for Stable Diffusion v1-4 that optimizes user input into model-preferred prompts, turning your rough idea into something the model can actually run with.

The online demo at Hugging Face Spaces is using CPU, so slow generation speed would be expected. Please load the model locally with GPUs for faster generation if you want to iterate quickly on prompts without staring at a loading bar.
