StealCut Protect is the world's first proactive deepfake defense solution that prevents deepfakes before they are created. In the generative AI era, image-based misuse is surging in many forms, from sexual deepfakes to impersonation fraud across social, dating, and creator platforms, which will only intensify. But existing tools can only react to the damage after it has occurred, through detection and removal. StealCut Protect works at the source instead. It injects an imperceptible protective noise that keeps a portrait photo visually identical and usable yet breaks any deepfake made from it. It pairs with StealCut Detect, our own AI-generated content detection model, to cover deepfake response end to end, from prevention to detection. Our mission is to build a 'Deepfake-Zero' society, where your face belongs to you alone and can never be weaponized.
