Preprocessor Contact Sheet for ComfyUI

A custom node that runs all ControlNet preprocessors on your image at once and displays the results in a single contact sheet grid. Then pick the one you like and inject its workflow directly into your canvas.

Features

  • Auto-discovery: detects which preprocessors from comfyui_controlnet_aux are installed on your system
  • Batch execution: runs all available preprocessors in sequence on the same image
  • Contact sheet output: composites all results into a labeled grid with color-coded categories
  • Visual grid picker (🎯 Pick from Grid): after running, opens an overlay with real thumbnails — click one to inject its workflow
  • AIO or Dedicated node: choose between the generic AIO Preprocessor (dropdown) or the dedicated node with full parameter control
  • Click-to-place: after choosing, click anywhere on the canvas to position the workflow — no overlapping
  • Detailed report: string output listing successes, failures, missing nodes, and skipped preprocessors
