Requires any commercial entity deploying a chatbot to clearly and conspicuously disclose to users that they are interacting with a chatbot, not a human. Chatbot interactions and representations are given the same legal force and effect as interactions with a human employee or agent of the commercial entity, and disclaimers cannot serve as a defense. Violations are treated as unfair or deceptive acts under Massachusetts Chapter 93A, enabling both Attorney General enforcement and private suits by consumers. The bill is notably broad — it covers all commercial chatbots regardless of modality (audio, visual, or text) and does not limit its scope to companion or high-risk chatbots.
