Maine
AI behavior law: bot and agent disclosure, crawler and training-data rules, automated-agent transactions, and algorithmic decision-making.
Summary
Maine has enacted a focused cluster of AI-behavior laws since 2025, targeting chatbot transparency in commercial transactions, deepfake intimate images, AI disclosure in political advertising, and AI use in mental health therapy. The cornerstone is the Chatbot Disclosure Act (LD 1727, effective September 16, 2025), which requires businesses to notify consumers when they are interacting with an AI chatbot in trade or commerce. Governor Mills's AI Task Force (established December 2024, report delivered November 2025) made 33 policy recommendations covering workforce, municipal capacity, and consumer protection, several of which have been translated into 2026 legislation. Maine has no enacted law specifically governing crawler access, AI training-data rights, or general automated-decision-making accountability; those categories remain unlegislated as of mid-2026.
