Manual Masking Watermark Remover

This workflow can remove watermarks, but they need to be manually drawn in using the Mask Editor.

Automatic Detection (Shutterstock Version)

The workflow can automatically remove watermarks from 'Shutterstock.'
It might work with other watermarks as well, but Shutterstock's are recognized the best.
Unfortunately, none of the YOLO watermark models work in ComfyUI, so I came up with a slightly cumbersome but functional way to remove the watermarks automatically.
