I was looking into GIMP tutorials on Youtube and stumbled upon this site. It seems very useful for quick edits.

Honestly, I didn't understand the pricing options. But it seems as long as you don't use the images in commercial use, the website application is good to go.

My try:

Quote from the site:
"We use sophisticated AI technology to detect foreground layers and separate them from the background. To improve the results we have several additional algorithms in place, for instance to improve fine details and prevent color contamination."

It only works on images of people:
"Our AI is trained to detect persons as foreground and everything else as background. That's why it only works if there is at least one person in the image."

So free to use for smaller images (max 625×400 pixels) if it saves time I would use it. Thanks for the link.
