In one paragraph

Massachusetts's S 243 (194th General Court) would add G.L. c. 93, section 115, declaring it an unfair and deceptive act under chapter 93A for a person, in a commercial transaction or trade practice with a consumer, to use a bot (such as a chatbot or AI agent) that may mislead a reasonable person into believing they are dealing with a human, whether or not anyone is actually misled. A person is not liable if the consumer is clearly and conspicuously told they are communicating with a computer. Reported favorably by the Consumer Protection and Professional Licensure Committee November 19, 2025 and referred to Senate Ways and Means; it has not passed either house.

What it means for business

None yet: the bill has not been enacted. Businesses using chatbots or AI agents with Massachusetts consumers would have to clearly and conspicuously disclose that it is a computer to avoid chapter 93A liability.
