    🧠 ComfyUI Grok Prompts

    AI-Powered Prompt Engineering Nodes for ComfyUI using xAI's Grok API.
    Fine-tune your prompt craft with LLM intelligence, split, recombine, and visualize prompt transformations, all inside ComfyUI.

    🔧 What is this?

    comfyui-grok-prompts is a modular node suite for ComfyUI that uses xAI’s Grok LLM API to transform user input into optimized prompts for AI models like PonyXL and Flux. These nodes intelligently:

    • ✂️ Split prompts into subject/scene (text_l) and style/mood (text_g)
    • 🔀 Combine and rewrite them into perfectly scored Danbooru-tagged prompts
    • 🎥 Output video prompts using Wan’s Advanced Prompt Formula
    • 💬 Display a UI explanation of how the prompt was refined
