## What it is
A collection of ComfyUI custom nodes providing ControlNet auxiliary preprocessors that generate hint images (Canny edges, lineart, depth maps, poses, etc.) for Stable Diffusion workflows. It packages the annotator code from the original ControlNet repository as plug-and-play nodes connected to Hugging Face model hosting.

## Use cases
- generate controlnet hint images in comfyui
- extract canny edges or lineart from images for stable diffusion
- preprocess depth or pose maps for controlnet conditioning
- install controlnet annotators as comfyui custom nodes
- convert photos to scribble or soft-edge guides for img2img control

## When to choose
- you use ComfyUI and want ControlNet conditioning without manual preprocessing
- you need a wide catalog of preprocessors (canny, lineart, depth, pose) in one plugin
- you want automatic model downloads from Hugging Face Hub

## When to avoid
- you use Automatic1111 or another UI instead of ComfyUI
- you need preprocessors outside the hint-image scope, such as inpainting
- you want a standalone CLI preprocessor not tied to ComfyUI

## Facets
- artifact type: plugin
