    🧩 Comfy Text Stats (Char & Word Count)

    A lightweight ComfyUI custom node that receives a text string and outputs:

    • 🧮 Character count (INT)
    • ✍️ Word count (INT)

    This node is designed for text preprocessing, caption analytics, or quick statistics inside your ComfyUI workflows.

    🚀 Features

    ✅ Simple and fast — no dependencies
    ✅ Unicode-aware word detection (supports multilingual text)
    ✅ Deterministic results (not affected by seeds)
    ✅ Works with any STRING input from other nodes

    🧠 Usage

    Node name

    Text Stats (Char & Word Count)
    Category: Text / Utils

    Inputs

    | Name | Type | Description | |------|------|--------------| | text | STRING | The text input to analyze. Supports multiline input. |

    Outputs

    | Name | Type | Description | |------|------|--------------| | char_count | INT | Number of characters (including spaces, punctuation, and newlines). | | word_count | INT | Number of words (using Unicode-aware regex). |

    🧪 Example

    Input text:

    ComfyUI makes custom nodes easy!

    Outputs:

    char_count = 33
word_count = 5

    🔧 Technical Details

    • Word detection uses the regex: 
      \b\w+\b
      which matches Unicode word boundaries.
    • The node is deterministic (IS_CHANGED checks text length for caching).

    💡 Use Cases

    • Text preprocessing for captioning or prompt tuning
    • Generating text metadata before feeding into LLM pipelines
    • Measuring caption sizes in dataset workflows
