Maine AI Laws: What's Enacted and What's Next (2027)

As of November 2026, Maine has enacted no comprehensive AI law, but it has two AI-specific consumer rules: the chatbot disclosure law at 10 MRSA 1500-DD (LD 1727, PL 2025 c. 294) and the limit on AI therapy at 10 MRSA 1500-EE (LD 2082, PL 2025 c. 687). Maine also has deepfake, child sexual abuse material and election synthetic media amendments.

How we searched: Where this page says we found no law, we mean the Maine Legislature's Bill Tracking and Text Search for the 132nd Legislature (2025 and 2026 sessions), using "artificial intelligence", "chatbot", "algorithm", "algorithmic", "machine learning", "automated decision" and "generative". That search matches words, not exact phrases, so we opened the enacted chapters it returned and searched them for the phrase. We did not sweep earlier legislatures or the whole Maine Revised Statutes.

This page covers Maine state law as of November 4, 2026. It is general legal information, not legal advice. For the national picture, see our guide to US AI laws.

Maine AI Laws at a Glance

Maine Chatbot Disclosure Law: 10 MRSA 1500-DD (LD 1727)

The rule at 10 MRSA 1500-DD was signed June 12, 2025, and took effect September 24, 2025. It was enacted as section 1500-Y and later reallocated. The operative sentence carries its own limit:

A person may not use an artificial intelligence chatbot or any other computer technology to engage in trade and commerce with a consumer in a manner that may mislead or deceive a reasonable consumer into believing that the consumer is engaging with a human being unless the consumer is notified in a clear and conspicuous manner that the consumer is not engaging with a human being.

The trigger is the risk of deception. A chatbot whose use could not mislead a reasonable consumer into thinking it is human does not trip the section by being a chatbot. The rule also reaches "any other computer technology," not only chatbots.

The statute defines an AI chatbot as "a software application, web interface or computer program that simulates human conversation and interaction through textual or aural communications." It reaches trade and commerce with consumers, as those terms are used in the Unfair Trade Practices Act.

Enforcement. A violation is a violation of the Maine Unfair Trade Practices Act. Under 5 MRSA 209, the Attorney General may bring an action to restrain a practice, and the court may order money or property restored. Violating an injunction carries a civil penalty of up to $10,000 per violation, and each intentional violation of section 207 of the act that the Attorney General proves was unfair or deceptive carries a civil penalty of up to $10,000.

Private suits. Under 5 MRSA 213, a person who buys or leases goods, services or property primarily for personal, family or household purposes and suffers a loss of money or property may sue for actual damages, restitution and other equitable relief. A written demand must come at least 30 days before an action for damages.

We found no reported enforcement of the section. The Attorney General's press-release index showed no AI company action when searched for this update, and web searches found no court challenge to a Maine AI statute. Those channels would not show every filing.

LD 2082: Maine's Limit on AI Therapy (10 MRSA 1500-EE)

LD 2082, signed April 13, 2026, took effect July 29, 2026, the general effective date for the session. Its core rule covers anyone offering therapy to the public:

A person may not provide, advertise or otherwise offer therapy or psychotherapy services, including through the use of Internet-based artificial intelligence, to the public unless the therapy or psychotherapy services are provided by a licensed professional.

"Therapy or psychotherapy services" means services to diagnose, treat or address an individual's mental or behavioral health through therapeutic communication, and that term is limited to interaction in a clinical or professional setting. A violation is a violation of the Unfair Trade Practices Act. AI-based interventions used solely within a research project approved by an institutional review board, and conducted under federal human-subject protections, are excepted.

What licensees may do. New sections for the licensing boards let a licensee use AI for administrative support or supplementary support, within the scope of practice, while keeping full responsibility for all interactions, outputs and data use.

Conditions. Supplementary support is allowed only when the session is recorded or transcribed, the client is told in writing that AI will be used, its specific purpose, and how session data is stored, retained, used for training and deleted, and the client consents.

What AI may not do. A licensee may not allow AI to make independent therapeutic decisions, directly interact with clients in therapeutic communication, or generate recommendations or treatment plans without the licensee's review and approval.

Other protections. A licensee may not deny treatment solely because a client refuses consent. A client's waiver is void and unenforceable. Violations are subject to board discipline, and each board must adopt rules, which the act classifies as major substantive rules. We did not confirm the status of those rules.

Maine Deepfake and Synthetic Media Laws in Brief

LD 517 added 21-A MRSA 1014(5-C). When a public communication that requires a disclosure contains synthetic media, it must carry the words "THIS COMMUNICATION CONTAINS AUDIO, VIDEO AND/OR IMAGES THAT HAVE BEEN MANIPULATED OR ALTERED." The act allows a civil penalty of up to 500 percent of the expenditure in violation.

Synthetic media here means an image, audio recording or video recording depicting a candidate that is likely to deceive a reasonable person into thinking the candidate said or did something the candidate did not, or that was manipulated or altered in a way likely to give a materially different impression. The definition does not mention AI. It excludes satire, parody, and clarity edits, captions and highlighting that do not change that impression. A broadcast, cable or satellite operator or a newspaper violates the rule only by running a paid communication with actual knowledge that it contains synthetic media.

17-A MRSA 511-A, as amended by LD 1944, reaches an image "created or modified so that it appears to show" a person in a state of nudity or a sexual act, where the person intends to harass, torment or threaten and the statute's other elements are met. It is a Class D crime.

LD 524 defines child sexual abuse material as "any image, including a computer-generated image, that depicts or has been created or modified so that it appears to depict a minor, regardless of whether that depiction is an identifiable child, engaged in sexually explicit conduct." It adds a Class B crime for intentionally or knowingly manufacturing or creating such obscene material, "including using generative AI or machine learning," by a person who knows or has reason to know what it is. Our guide to Maine deepfake laws has the elements and exceptions.

State Government and the Maine AI Task Force

Governor Mills created the Maine Artificial Intelligence Task Force by executive order on December 20, 2024, with 21 members. An executive order is not a statute, and it does not regulate private companies.

PL 2025 c. 650 (LD 2212), a supplemental budget approved April 10, 2026, funds items it describes as following the task force's recommendations. They include state employee AI training, educator grants, a position to coordinate state AI policy, and a public literacy and safety program.

The Legislature also passed study resolves that touch AI, including LD 2052 on technology in classrooms and LD 109 on protecting artists from AI copyright infringement. Those direct studies and do not regulate private AI use.

What We Did Not Find in Maine Law

In the search described at the top of this page, through November 4, 2026, we found no Maine act on AI in employment decisions or health insurance decisions, no comprehensive AI or automated decision law, no frontier model law, and no chatbot law aimed at minors.

Maine is not on the National Association of Insurance Commissioners' list of states acting on its model bulletin on insurers' use of AI, in the list's status as of November 3, 2026. That list may lag, and we did not search the Maine Bureau of Insurance's own bulletins.

General laws such as the Maine Human Rights Act are not AI laws, and this page does not cover how a court would apply them to AI.

Maine AI Bills That Did Not Pass

These are not law. Each entry is the final disposition on the Legislature's bill page, read for this update.

How Federal AI Policy Affects Maine

As of November 4, 2026, we found no federal statute in the public laws of the 119th Congress that sets general rules for private AI systems or generally preempts state AI laws. In December 2025, Executive Order 14365 directed federal agencies to challenge or discourage state AI laws the administration views as conflicting with national policy, and called for a federal framework from Congress. The order itself does not declare any state law invalid.

The Justice Department formed an AI Litigation Task Force in January 2026, the White House issued legislative recommendations in March 2026, and the FTC proposed a policy statement in July 2026. Separately, in April 2026 the Justice Department intervened in a lawsuit against Colorado's AI law under the Civil Rights Act of 1964. We did not find a published Commerce evaluation of state laws in the Federal Register or on ntia.gov, or a BEAD notice carrying the order's AI condition on NTIA's sites.

What Changes in Maine AI Law in 2027

As of November 4, 2026, we found no AI law scheduled to take effect in Maine in 2027; we searched the Maine Legislature's Bill Tracking and Text Search for the 2025 and 2026 sessions.

The 132nd Legislature adjourned April 29, 2026, and the bills above are finished. We did not review any bill filed for the next Legislature. The licensing board rules LD 2082 requires are the one open item we know of, and the act as we read it sets no date for them.

Frequently Asked Questions

Does Maine have an AI law?

Maine has no comprehensive AI law that we found. It has targeted laws: a chatbot disclosure rule at 10 MRSA 1500-DD, a limit on AI therapy under LD 2082, and deepfake, child sexual abuse material and election synthetic media amendments.

Do Maine businesses have to disclose chatbots?

When a chatbot or other computer technology is used in trade and commerce with a consumer in a way that may mislead or deceive a reasonable consumer into believing they are engaging with a human, the consumer must be notified in a clear and conspicuous manner. The law does not require a notice where that risk is absent.

Who enforces Maine's chatbot law?

A violation is a violation of the Maine Unfair Trade Practices Act. The Attorney General may seek an injunction, and civil penalties of up to $10,000 for intentional unfair or deceptive violations, under 5 MRSA 209, and a consumer who suffers a loss of money or property in a personal, family or household purchase may sue under 5 MRSA 213.

Is AI therapy legal in Maine?

LD 2082 bars providing, advertising or offering therapy or psychotherapy services to the public, including through Internet-based AI, unless a licensed professional provides them. Licensees may use AI for administrative or supplementary support under conditions, and an IRB-approved research exception applies.

Does Maine require AI disclosures in political ads?

LD 517 requires set words on a public communication that needs a disclosure and contains synthetic media, which the statute defines by what a depiction of a candidate shows, not by whether AI made it. A violation may bring a civil penalty of up to 500 percent of the expenditure in violation.

Does Maine regulate AI in health insurance decisions?

We found no Maine act on it in the 132nd Legislature. LD 955 and LD 1301 received Ought Not to Pass dispositions. Maine is also not on the NAIC list of states acting on its AI model bulletin as of November 3, 2026, though that list may lag.

What AI laws take effect in Maine in 2027?

As of November 4, 2026, we found none in the Maine Legislature's text search for the 2025 and 2026 sessions.
