SDXL Prompt Styler

Custom node for ComfyUI

SDXL Prompt Styler is a node that enables you to style prompts based on predefined templates stored in a JSON file. The node specifically replaces a {prompt} placeholder in the 'prompt' field of each template with provided positive text.

The node also effectively manages negative prompts. If negative text is provided, the node combines this with the 'negative_prompt' field from the template. If no negative text is supplied, the system defaults to using the 'negative_prompt' from the JSON template. This flexibility enables the creation of a diverse and specific range of negative prompts.

Usage Example with SDXL Prompt Styler

Template example from a JSON file:

[
    {
        "name": "base",
        "prompt": "{prompt}",
        "negative_prompt": ""
    },
    {
        "name": "enhance",
        "prompt": "breathtaking {prompt} . award-winning, professional, highly detailed",
        "negative_prompt": "ugly, deformed, noisy, blurry, distorted, grainy"
    }
]

style = "enhance"
positive_prompt = "a futuristic pop up tent in a forest"
negative_prompt = "dark"

This will generate the following styled prompts as outputs:

breathtaking a futuristic pop up tent in a forest . award-winning, professional, highly detailed
ugly, deformed, noisy, blurry, distorted, grainy, dark
