Questions

Is it free?

AI Background Remover is part of Knack Pro, a one-time purchase with no subscription.

Does it need an internet connection?

No. The AI model runs on your Mac's Neural Engine, so it works offline and nothing is uploaded.

Can I process many photos at once?

Yes. Drop a folder and Knack processes every image in it.

One app, 20+ tools.

AI Background Remover is one of more than twenty native tools in Knack — converters, PDF tools, OCR, AI photo tools and more, all running on your Mac.
