ComfyUI Node: 😺NKD Klein Prompt Builder

😺NKD Klein Prompt Builder:

The NKDKleinPromptBuilder is a specialized node designed to assist you in crafting prompts for Klein by seamlessly integrating your custom text with a selection of curated presets that Klein can interpret effectively. This node is particularly beneficial for those looking to generate detailed and nuanced prompts, as it allows you to input your subject matter and select from various dropdown options to enhance the prompt with specific attributes such as style, mood, and lighting. The node dynamically assembles the final prompt, which is displayed in real-time in a preview box, ensuring you can see the results of your selections immediately. The output can be formatted in two ways: as flowing prose, which is optimal for Klein, or as a structured JSON template, which is useful for automation purposes. The presets used by this node are sourced from a file named klein_presets.json, which you can customize to better suit your needs by editing the file and restarting ComfyUI.
