DynamicPrompts Custom Nodes Introduction

Welcome to comfyui-dynamicprompts, a powerful extension designed to enhance your experience with ComfyUI by integrating dynamic prompt generation capabilities. This extension provides a set of custom nodes that allow you to create varied and interesting prompts for your AI art projects. Whether you're looking to add randomness, explore all possible combinations, or get inspired by related prompts, comfyui-dynamicprompts has you covered.

  • I'm Feeling Lucky: Get inspired by downloading related prompts from
  • Magic Prompt: Enhance your prompts with relevant modifiers using a neural network.
  • Jinja2 Templates: Write complex prompts using the powerful Jinja2 templating language. By using comfyui-dynamicprompts, you can overcome creative blocks, experiment with different styles, and generate a wide variety of prompts effortlessly.

How DynamicPrompts Custom Nodes Works

At its core, comfyui-dynamicprompts leverages a set of custom nodes that you can integrate into your existing ComfyUI workflows. These nodes allow you to define templates with placeholders and rules for generating dynamic prompts. Here's a simple analogy to help you understand:

Imagine you have a recipe book (your prompt template) with ingredients (placeholders) that can be swapped out for different items (random or combinatorial elements). comfyui-dynamicprompts helps you create new recipes (prompts) by mixing and matching these ingredients in various ways.

Basic Principles:

  1. Templates: Define a base structure for your prompts with placeholders.
  2. Randomization: Use nodes to randomly select elements for your placeholders.
  3. Combinations: Iterate through all possible combinations of elements.
  4. Enhancements: Add modifiers and related prompts to enrich your base template. By combining these principles, you can generate a diverse set of prompts that can inspire and guide your AI art projects.

DynamicPrompts Custom Nodes Features

Random Prompts

This feature allows you to generate prompts with random elements. For example, if you have a template like "A {red|green|blue} ball," the Random Prompts node will randomly choose one of the colors each time it generates a prompt.

Combinatorial Prompts

The Combinatorial Prompts node iterates through every possible combination of elements in your template. For example, "A {red|green|blue} ball" will generate:

  • A red ball
  • A green ball
  • A blue ball

I'm Feeling Lucky

This node uses your base prompt to fetch a related prompt from It's like having a creative assistant that suggests new ideas based on your initial input.

Magic Prompt

Magic Prompt employs a neural network to add relevant modifiers to your base prompt. For instance, "A beautiful landscape" might be enhanced to "A beautiful landscape with rolling hills and a sunset."

Jinja2 Templates

For advanced users, Jinja2 Templates allow you to write complex prompts using the Jinja2 templating language. This feature is useful for creating highly customized and dynamic prompts.
