cd ComfyUI/custom_nodes/
git clone https://github.com/USERNAME/ComfyUI_PromptBatcher.git

2. Restart ComfyUI

Usage

The extension adds a new node called "Load Prompts From Dir" in the JMNodes category.

Node Inputs

• directory: Path to the folder containing your prompt text files
• file_prefix (optional): Only load files that start with this prefix
• file_load_cap (optional): Limit the number of files to load (0 = no limit)
• start_index (optional): Start loading from this index in the file list
• load_always (optional): Force reload files on every execution

Node Outputs

• PROMPT: A list of prompt strings loaded from the text files
• FILE_PATH: A list of absolute file paths for the loaded files

Example Workflow

1. Add the "Load Prompts From Dir" node
2. Connect it to a "KSampler (Advanced)" node
3. Set up a batch workflow to process each prompt in sequence

Example Directory Structure

prompts/
├── prompt1.txt
├── prompt2.txt
└── prompt3.txt

Each text file should contain a single prompt.
