ComfyUI Node: SDXL Prompt Styler

SDXL Prompt Styler:

The SDXLPromptStyler node is designed to enhance and style your text prompts for AI art generation. It allows you to apply predefined styles to both positive and negative prompts, ensuring that your input text aligns with the desired artistic direction. This node is particularly useful for artists looking to maintain consistency in their prompts or experiment with different stylistic approaches. By leveraging templates and styles, the SDXLPromptStyler can transform your basic text inputs into more sophisticated and contextually rich prompts, ultimately improving the quality and coherence of the generated artwork.

SDXL Prompt Styler Input Parameters:

text_positive

This parameter accepts a string input for the positive prompt, which is the main descriptive text you want to style. The positive prompt is crucial as it directly influences the generated artwork's content. The default value is an empty string, and it supports multiline input for more complex descriptions.

text_negative

This parameter accepts a string input for the negative prompt, which specifies elements you want to exclude from the generated artwork. Like the positive prompt, the negative prompt can significantly impact the final output by guiding the AI to avoid certain features. The default value is an empty string, and it supports multiline input.

style

This parameter allows you to select a predefined style from a list of available styles. The chosen style will be applied to both the positive and negative prompts, enhancing their coherence and artistic direction. The styles are loaded from a directory and provide various thematic and aesthetic options.

log_prompt

This boolean parameter enables or disables logging of the prompts. When set to "yes," the node will print the style, positive and negative text, and the styled prompts to the console, which can be useful for debugging and fine-tuning. The default value is "yes."

style_positive

This boolean parameter determines whether the positive prompt should be styled. When enabled, the positive prompt will be transformed according to the selected style. If disabled, the positive prompt remains unchanged. The default value is "yes."

style_negative

This boolean parameter determines whether the negative prompt should be styled. When enabled, the negative prompt will be transformed according to the selected style. If disabled, the negative prompt remains unchanged. The default value is "yes."

SDXL Prompt Styler Output Parameters:

text_positive

This output provides the styled positive prompt. It reflects the original positive text input transformed according to the selected style, enhancing its artistic coherence and thematic alignment.

text_negative

This output provides the styled negative prompt. It reflects the original negative text input transformed according to the selected style, ensuring that the specified exclusions are contextually appropriate and consistent with the overall artistic direction.

SDXL Prompt Styler Usage Tips:

• Experiment with different styles to see how they affect the output of your AI-generated artwork. This can help you find the best stylistic match for your project.
• Use the logging feature to understand how your prompts are being transformed. This can provide insights into how different styles impact your text and help you fine-tune your inputs.
• If you want to maintain the original negative prompt while styling only the positive prompt, disable the style_negative parameter.
