ComfyUI_StringTools

Custom nodes for ComfyUI that enhance functionality by allowing text string modifications.

ModifyStringNode

Supports operations such as substring removal and replacement with other substrings. Useful for altering prompts and outputs generated by large language models (LLMs), enabling refinement of text outputs.

To add the Modify String node: Add Node > StringTools > Modify String

Note: On first use, you may need to drag and resize the Modify String node to see all the text and options.

ShowStringNode

A simple node to display a string in the node itself. To see changes made by the Modify String node, you can link output_string to the input_string of the Show String node.

To add the Show String node: Add Node > StringTools > Show String

Usage Example

TextStringNode

A simple multiline text string node with the ability to remove whitespace or newlines if required.

ReplaceStringNode

Replace a string, such as the word prompt, with a multiline text string.
