# String Essentials - Custom nodes for ComfyUI

Custom nodes for ComfyUI that provide text/string manipulation capabilities. Particularly useful for modifying text from LLM outputs (Ollama, Claude.ai, OpenAI ChatGPT), such as prompts or image-to-text description results.

## Features
- Remove or replace text, words, numbers in input strings
- Handle multi-word strings (partial sentences/phrases)
- Case-sensitive/insensitive matching
- Whole string matching option

## String Strip Node
Removes specified strings from input text. Each line should contain the string to be searched. The string can contain multiple words. To match individual words/strings place on seperate lines.

- **`strings_to_remove`**: List of strings to remove (one per line)
- **`match_case`**: Enable/disable case-sensitive matching
- **`match_whole_string`**: Ensure only exact matches are removed
- **`remove_extra_spaces`**: Clean up extra spaces after removal
