Maine's AI disclosure rule reaches a phone, and it says so

Title 10 §1500-DD took effect on 1 October 2025. The word that matters is aural: the definition covers spoken conversation, so an AI receptionist is inside it.

The short version

  • A business may not use an AI chatbot in trade or commerce in a way that could mislead a reasonable consumer into thinking they are dealing with a human.
  • The exception is clear and conspicuous notification. Tell the caller, and the problem goes away.
  • The definition covers textual and aural conversation, which is why this reaches a receptionist rather than only a website widget.
  • This is the clearest inbound-facing AI disclosure duty we found anywhere in the United States.

Why the word aural does the work

Most AI disclosure rules were drafted with chat windows in mind, and it shows in the wording. Maine covers talk that is written or spoken, and that one word pulls voice into scope. A firm using an AI to answer its phone in Maine is using an AI chatbot in trade, as the law puts it.

The test is whether a normal shopper could be misled into thinking they are dealing with a person. Sit with that, because it is the exact thing many vendors here advertise. Copy promising an assistant nobody can tell from a person is describing the very thing the law makes actionable.

We do not write that sentence about our own product for that reason, among others. An assistant that announces itself is not a weaker product; it is a product that has read the rule.

What clear and conspicuous means in a phone call

The law gives you an out if the caller is told clearly. On a phone call the natural reading is that the notice comes first, before the caller has said anything that matters, and in words a person actually follows.

A line like this is what most businesses use: you are speaking with an automated assistant for the practice, and I can book appointments or take a message. It takes about three seconds, and it tells the caller both that it is an AI and what it can do for them.

A buried notice is the failure here. A line on your website, or one at the end of the call, or a mention in terms nobody reads, is hardly clear to a caller who has spent two minutes thinking they reached a person.

What this means if you are not in Maine

It means less than the alarmed reading suggests and more than the dismissive one does. Maine applies to trade or commerce in Maine, so a business elsewhere is not automatically inside it. If you take calls from Maine consumers, ask your counsel how that applies to you.

The wider point is which way this is going. Maine and Utah landed on disclosure duties within a year of each other, by different routes, and the FCC has a proposal in the same area. Building on callers not knowing they reached software is building on ground that moves one way.

The answer is the same either way. Turn the notice on. It costs three seconds. From writing these greetings, we find callers who know give cleaner details, because they use the short plain sentences people use with a machine rather than the rambling ones they use with a person.

The usual caveat, which is a real one here

Hear it handle one of your own calls

Your scenario, your greeting, a couple of minutes.
