Busy photos with several possible subjects are the real test here. Being able to keep “the dog bowl” instead of drawing a rough mask sounds genuinely useful, and alpha mattes are the right fit for hair, blur, and semi transparent edges.

MultiMatte is an image background removal software that accepts textual prompts to specify which objects to keep in images while removing the rest. It produces alpha mattes for fine, translucent, or complex boundaries, improving on previous segmentation models. Built on SAM 3, MultiMatte offers high-accuracy background removal with intuitive text input and provides a usable API via the NoBg Python library and a web demo.

very cool! can we also just oultine trace / approx as hints on input image (or feed it two images, say raw and markup image with whatever visual hints use?

This is awesome. Does the demo run fully client-side? This is at least as good as my current solution (Preview.app -> Tools -> Remove Background), I generally pre-crop so it's not too hard to get just the object I care about.

I tried it with an image that most background remover tools fail on - but MultiMatte did it perfectly! Very well done! The image in question is a photo of me and horse with a fenceline and paddock and some trees in the background. Most tools get confused with the colours in the foreground and the fence and sky colours.

Perfect timing since canva is shutting down remove.bg ("moving it to the canva platform") -- this looks great!
