This is pretty impressive, there's still some artifacts in this image that I put into the demo - but it did do a better job of selecting the correct edges than either Photoshop or remove.bg.

The more I use it, the more this feels like it definitely has a long way to go. There's a bad habit of making random parts of the image semi-transparent despite them being high contrast relative to the background, and it doesn't do as good of a job removing exterior halos around objects as I'd like.
