Maine AI bills
RSS feed for MaineAn Act to Regulate and Prevent Children's Access to Artificial Intelligence Chatbots with Human-like Features and Social Artificial Intellig…
Not law. Maine's LD 2162 would have regulated AI chatbots and social AI companions offered to minors in Maine. As amended by committee amendment C-A, which both chambers adopted, deployers would have had to keep chatbots' human-like features and social AI companions away from minors starting February 15, 2027, and maintain systems to detect, respond to, report and mitigate situations where a minor indicates an intent to harm themselves or others. The Attorney General could seek civil penalties up to $2,500 per violation ($7,500 if intentional), and minors could sue. The bill died on adjournment April 29, 2026.
An Act to Protect Children from Technology-facilitated Sexual Abuse
Maine's 2026 emergency law closes a gap that kept police from charging AI-generated child sexual abuse material. It redefines child sexual abuse material to include computer-generated images created or modified to appear to depict a minor, defines generative AI or machine learning and 'identifiable child', and makes it a Class B crime to alter an image of an identifiable child into such material or to create obscene child sexual abuse material, including with generative AI. Disseminating or possessing obscene AI-generated material is also criminalized. It took effect on approval, April 16, 2026.
An Act to Regulate the Use of Artificial Intelligence in Providing Certain Mental Health Services
Maine's LD 2082 (Public Law chapter 687) bars any person from providing, advertising or offering therapy or psychotherapy services to the public, including through Internet-based AI, unless a licensed professional provides them; violations fall under the Maine Unfair Trade Practices Act. Licensed therapists may use AI for administrative or supplementary support (such as therapy notes) only if they keep full responsibility; supplementary use requires a recorded or transcribed session, written notice and client consent, and AI may not make independent therapeutic decisions or interact with clients therapeutically. Signed April 13, 2026.
An Act to Enact the Maine Online Data Privacy Act
Not law. Maine's LD 1822, the Maine Online Data Privacy Act, as introduced would have applied to controllers handling data of 35,000 or more consumers (or 10,000 with over 20% of gross revenue from data sales). Consumers could have accessed, corrected and deleted data and opted out of targeted advertising, sales and profiling in furtherance of solely automated decisions with legal or similarly significant effects. It would have banned selling sensitive data and required data protection assessments, including for risky profiling. Committee amendment C-A and later floor amendments were adopted. The Attorney General would have enforced it exclusively. It died between houses April 13, 2026.
An Act Regarding Synthetic Media in Campaign Advertising
Maine requires campaign ads that contain 'synthetic media' of a candidate to carry the disclosure 'THIS COMMUNICATION CONTAINS AUDIO, VIDEO AND/OR IMAGES THAT HAVE BEEN MANIPULATED OR ALTERED.' Synthetic media is an image, audio or video of a candidate that deceptively shows them saying or doing something they did not, or is altered to give a materially different impression; clarity edits, captions, satire and parody are excluded. Violations can bring civil penalties of up to 500% of the expenditure, and the Attorney General can seek injunctions. Broadcasters and newspapers are liable only with actual knowledge. Effective July 29, 2026.
An Act to Prohibit the Use of Artificial Intelligence in the Denial of Health Insurance Claims
Not law. Maine's LD 1301 would have set conditions, beginning January 1, 2026, on health insurance carriers and their contractors that use artificial intelligence in medical or utilization review decisions to approve, deny, delay or modify coverage. Despite its title, it did not ban AI. AI determinations would have had to rest on the enrollee's medical history and clinical circumstances and not supplant provider decision-making, and could not discriminate. Any denial, delay or modification based on medical necessity would have needed a clinical peer. The committee voted Ought Not To Pass on January 14, 2026; final disposition January 27, 2026.

Maine's LD 109 is a resolve directing the Maine Arts Commission, consulting the Attorney General's office, to study federal and national efforts to protect artists from copyright infringement by businesses and others that promote, create, disseminate or use AI software, and efforts to monitor educational use of copyrighted work, and to report with any suggested legislation by December 3, 2025. It appropriates $25,000 for a consultant. Held by the Governor in July 2025, it became law without signature on January 11, 2026 (Resolves chapter 121), after that report date.
An Act to Enact the Maine Consumer Data Privacy Act
Not law. Maine's LD 1088, the Maine Consumer Data Privacy Act, as introduced would have applied to controllers handling data of 100,000 or more consumers (50,000 from 2028), or 25,000 with more than 25% of gross revenue from data sales. Consumers could have accessed, corrected, deleted and ported data and opted out of targeted advertising, sales and profiling in furtherance of solely automated decisions with legal or similarly significant effects. The Attorney General would have enforced it exclusively, with no private right of action. The Judiciary Committee split three ways on June 13, 2025, and Report A, Ought Not To Pass, was accepted June 25, 2025.
An Act to Protect Individuals from the Threatened Unauthorized Dissemination of Certain Private Images, Including Artificially Generated Pri…
Maine's LD 1944 (Public Law chapter 400) expands the crime of unauthorized dissemination of certain private images (17-A MRSA §511-A) to cover an image created or modified so that it appears to show the depicted person nude or engaged in a sexual act or sexual contact, and defines "image" to include anything made, captured, generated or saved, such as computer data files, animations and livestreams. It also makes threatening to commit that crime harassment under 5 MRSA §4651 and adds such threats to the conduct listed in 19-A MRSA §4102. Signed June 20, 2025.
An Act to Ensure Transparency in Consumer Transactions Involving Artificial Intelligence
Maine's chatbot disclosure law adds a chapter on communications with consumers via artificial intelligence to Title 10. A person may not use an artificial intelligence chatbot or other computer technology to engage in trade and commerce with a consumer in a way that may mislead or deceive a reasonable consumer into believing they are talking with a human, unless the consumer is clearly and conspicuously notified that they are not dealing with a human. A violation is a violation of the Maine Unfair Trade Practices Act.
An Act Regarding Artificial Intelligence in Campaign Advertising
Not law. Maine's LD 1690 would have required political communications using images, audio or video that have been materially manipulated or altered and contain 'synthetic media' to carry the statement 'THIS COMMUNICATION CONTAINS AUDIO, VIDEO AND/OR IMAGES THAT HAVE BEEN MANIPULATED OR ALTERED.' Violations could draw penalties up to 500% of the expenditure with no 10-day cure, and the Ethics Commission could seek an injunction. The committee voted Ought Not To Pass May 19, 2025; final disposition May 27, 2025. A separate bill, LD 517 (synthetic media in campaign advertising), was enacted as Chapter 593, signed March 23, 2026.
An Act To Increase Privacy and Security by Regulating the Use of Facial Surveillance Systems by Departments, Public Employees and Public Off…
Maine's 2021 facial surveillance law (25 MRSA §6001) generally prohibits government departments, public employees and officials from obtaining, using or contracting for facial surveillance systems, defined as automated or semi-automated processes that identify people from facial characteristics. Limited exceptions allow searches for serious crimes with probable cause, missing or deceased persons and BMV fraud, but requests must go through the BMV or State Police, which log them. A facial match alone cannot establish probable cause, and illegally obtained data must be deleted and is inadmissible.
