This package introduces modal web interfaces (APIs) built directly into ComfyUI to seamlessly combine structured text lists, manual text blocks, and local LLM features via Ollama (both text enrichment and vision capabilities) without cluttering your node graph. It also includes List Constructor, a standalone browser utility for building, cleaning, organizing, and exporting prompt lists before using them inside MetaPrompt workflows.<h2 id="features-overview">🚀 Features Overview</h2><ul><li>🧠 MetaPrompt Node: A dynamic prompt builder that reads text lists (<code>.txt</code> / <code>.csv</code>) and manual chunks. Features separate text separators, independent randomization seeds, and a fully reactive embedded <code>.txt/.csv</code> directory browser within a popup modal window.</li><li>🧠 MetaPrompt Ollama Node: Inherits the core block prompt builder and injects a runtime prompt enhancement step utilizing your local Ollama models (<code>/api/chat</code> or <code>/api/generate</code>). Perfect for automatically upgrading sparse concept ideas into highly detailed generation prompts.</li><li>🖼️ ImageToPrompt Ollama Node: A dedicated local vision captioning node. Connect a standard ComfyUI <code>IMAGE</code> tensor input or configure a continuous batch folder scan to leverage local visual large language models (VLLMs) for generating precise descriptive prompts.</li><li>🧰 List Constructor Utility: A standalone web utility for creating, labeling, cleaning, sorting, copying, importing, and exporting prompt lists (<code>.txt</code>, <code>.csv</code>, and reusable <code>.js</code> configurations).</li></ul><hr /><h2 id="installation">🛠️ Installation</h2><h3 id="method-1:-via-comfyui-manager-(recommended)">Method 1: Via ComfyUI Manager (Recommended)</h3><ol><li>Open the ComfyUI Manager inside your ComfyUI interface.</li><li>Search for <code>Orion4D MetaPrompt</code>.</li><li>Click Install, then restart ComfyUI.</li></ol><h3 id="method-2:-manual-installation">Method 2: Manual Installation</h3>Clone this repository directly into your ComfyUI <code>custom_nodes</code> directory:<pre><code>cd /path/to/ComfyUI/custom_nodes/
git clone https://github.com/orion4d/Orion4D_MetaPrompt.git</code></pre>Restart your ComfyUI server after cloning.💡 Prerequisite for LLM Features: To use the Ollama nodes, ensure you have <a target="_blank" rel="ugc" href="https://ollama.com/">Ollama installed locally</a> and running (<code>ollama serve</code>). Make sure to pull the models you wish to use (e.g., <code>ollama pull qwen3-vl:4b</code>, <code>ollama pull gemma4:12b</code>).<hr /><h2 id="standalone-utility:-list-constructor">🌐 Standalone Utility: List Constructor</h2>List Constructor is a companion browser utility designed to prepare clean prompt lists before using them in MetaPrompt or any other prompt-generation workflow. It is especially useful for building reusable <code>.txt</code> / <code>.csv</code> list files, organizing prompt fragments by category, and quickly cleaning large batches of text entries.🔗 Live utility: <a target="_blank" rel="ugc" href="https://orion4d.github.io/Orion4D_MetaPrompt/List_Constructor/">Open List Constructor</a> 📦 Repository: <a target="_blank" rel="ugc" href="https://github.com/orion4d/Orion4D_MetaPrompt">Orion4D_MetaPrompt on GitHub</a><h3 id="key-features">Key Features</h3><ul><li>Label-based organization: Create, rename, color-code, and manage custom labels for prompt entries.</li><li>Fast list editing: Add single notes, paste raw multiline text, remove duplicates, remove empty entries, and apply prefix/suffix operations.</li><li>Text cleanup tools: Search and replace text across all entries, sort alphabetically, or sort by label.</li><li>Clipboard workflow: Copy the current list directly to the clipboard for quick reuse.</li><li>Export options: Export the full list as <code>.txt</code>, export only selected labels, or import existing <code>.txt</code> / <code>.csv</code> lists.</li><li>Reusable configurations: Save and reload complete List Constructor sessions as <code>.js</code> configuration files, including title, labels, colors, and note contents.</li></ul><h3 id="recommended-workflow">Recommended Workflow</h3><ol><li>Open the standalone List Constructor utility.</li><li>Paste or create your prompt fragments, keywords, style blocks, subject lists, or category lists.</li><li>Clean and organize them using labels, sorting, duplicate removal, prefix/suffix, or search/replace.</li><li>Export the result as <code>.txt</code> / <code>.csv</code>, then load it inside the MetaPrompt node directory browser.</li></ol><hr /><h2 id="deep-node-reference">📖 Deep Node Reference</h2><h3 id="1.-metaprompt">1. 🧠 MetaPrompt</h3>Designed to eliminate spaghetti workflows caused by hundreds of combined primitive strings or random selectors.<ul><li>Modal UI UI Interface: Click "Open APP" on the node to open a full-screen environment.</li><li>Dynamic Chaining: Add as many blocks as you want.
