ComfyUI-MieNodes is a plugin for the ComfyUI ecosystem, offering a series of utility nodes designed to simplify workflows and enhance efficiency.

Current Features

LoRA Training Caption Preparation Features

The plugin provides the following utility nodes, with a focus on dataset file management tasks in LoRA training workflows:

  1. Batch edit caption files (Insert/Append/Replace operations).
  2. Batch rename files, add prefixes, and format file numbering for specific file types.
  3. Synchronize image and caption files, with support for automatically creating or removing .txt files to match image files.
  4. Batch read caption files, with support for extracting all file contents for analysis and summarization by large language models.
  5. Batch convert image files, enabling conversion of all image files to a specified format (.jpg or .png).
  6. Batch delete files with the specified extension and optional prefix.
  7. Remove duplicated (same content) image files in the specified directory.
  8. Save any data as a file in TOML, JSON, or TXT format.
  9. Compare two files (in TOML or JSON format) and return the differences.

Common Features

The plugin also provides utility nodes for general-purpose tasks:

  1. Display any input as a string.
  2. Download files from huggingface, hf-mirror, github or anywhere to models folder.
