  • Matching filenames - ComfyUI_00217_.png + ComfyUI_00217_.txt guaranteed to match
  • Multiple formats - txt (human-readable), workflow (loadable JSON), or none
  • Auto-capture - Automatically extracts workflow info from ComfyUI context
  • Preview support - Shows image preview in node like standard SaveImage
