SB 452 Montana Senate · 2025 Regular Session

Require disclosures of AI use by online media manufacturers

SB 452 would require online media manufacturers (not government entities) to disclose when artificial intelligence curates or controls content users see and provide an opt-out option. It mandates visible markers on AI-generated content - like watermarks or labels - to alert users, even if original markers are removed. The bill defines "artificial intelligence" as systems that mimic human behavior to shape information flow and specifies "markers" as clear visual or audio disclosures. The bill died in committee in May 2025 and is not law.
