Our take: MultiMatte is a good fit for trying text-steered background removal that keeps soft edges like hair, with free web demo access.

Main limitation: The demo only accepts PNG, JPEG, WebP and HEIC images up to 4 MB and results come from the vendor's own benchmarks.

What is MultiMatte, and how does it work?

MultiMatte is a background removal model from Feyn Labs that you aim with words. You name the object to keep and the model removes everything else, producing alpha mattes with continuous opacity so hair and translucent edges are preserved. It is built on Meta's SAM 3, fine-tuned with LoRA on about 20,000 images. The Feyn field note reports higher S-measure scores than SAM 3 on the DIS benchmark, and a demo page lets users upload or paste an image and enter an optional prompt. The demo page is labelled open weights.
