Demo is running slow - cutting out is an impressive ability - I'm to assume it also fills in the background? If so: that's next level. Maybe that Photoshop monthly subscription will be worth it (providing this sort of ability is going to be baked in with AdobeAI's version soon)
It doesn't fill in the background and has nothing to do with Adobe.
You could bring the cut-outs back into Photoshop. I tried that, but this SAM tool reduces the size of the cut-outs slightly, so the cut-out won't match original image dimensions.
I know. Masking and selecting is something you do in Adobe products and Adobe will be coming out with their own version of this (if I were a betting man)
