ComfyUI Conditional Prompt Append

A custom node for ComfyUI that provides advanced, condition-based prompt appending. It allows you to dynamically build prompts based on the presence or absence of specific tags.

Features

• Conditional Appending (Core Feature): Choose exactly when to append your new prompts:
  • Always: Appends the prompt regardless of search results.
  • If Detected: Appends only if the search prompt is found in the base prompt.
  • If Not Detected: Appends only if the search prompt is missing from the base prompt.
• Additional Search Logic: Supports AND / OR logic when searching for multiple tags.
• Weight Management: Automatically groups the appended tags and applies a single weight bracket around them (e.g., (tag1, tag2:1.2)).
• Duplicate Prevention: Includes a skip_duplicate option to prevent adding tags that already exist in the base prompt.
• Flexible Delimiters: Fully supports multiline text inputs and custom delimiters (e.g., parsing line breaks into commas automatically).
• Position Control: Choose to append new prompts to the front or back of the base prompt.

Installation

1. Navigate to your ComfyUI custom nodes directory:

   cd ComfyUI/custom_nodes/
   

2. Clone this repository:

   git clone https://github.com/COkedat/comfyui-prompt-append
   

3. Restart ComfyUI.
4. You can find the node under the utils/prompt category, named Conditional Prompt Append.

How to Use

• base_prompt: Your main prompt text.
• search_prompt: The tags you want to search for within the base_prompt.
• search_logic: Determines whether to use AND or OR logic when searching for multiple tags.
• append_prompt: Additional Prompt text you want to add conditionally.
• condition: Choose the exact condition for appending the new prompts (Always, If Detected, If Not Detected).
• input_delimiter: The delimiter used to split the input prompts (base_prompt, search_prompt, append_prompt).
• output_delimiter: The delimiter used to join the tags in the final output prompt.
• skip_duplicate: Prevents adding prompts from the append_prompt that already exist in the base_prompt.
• position: Choose whether to add the new tags to the front or back of the base prompt.
• prompt (Output): The final resulting prompt text.
• is_detected (Output): Outputs a BOOLEAN (True/False) indicating whether the search tags were found, which can be routed to other logic nodes.
