Binding law — in force

Do not make available a tool whose primary purpose is unauthorized digital depictions of an identified person (Montana HB 513, sec. 1(3)(a))

From 2026-01-01, a person is liable if, without the consent of the individual or the holder of the individual's property rights, it distributes, transmits or otherwise makes available to the public an algorithm, software, tool or other technology, service or device with actual and specific knowledge that its primary purpose is to produce one or more unauthorized digital voice depictions or digital visual depictions of the particular, identified individual for commercial use (2025 Mont. Laws ch. 685, sec. 1(3)(a)). A digital voice or visual depiction is a newly created, computer-generated, highly realistic rendering of an individual's voice or likeness, nearly indistinguishable from the real one, that a reasonable person believes genuine. The rights last for life and 20 years after death. Detect a voice-clone or face-swap tool with no authorization gate.
