On April 21, 2026, the Connecticut Senate voted 32-4 to pass amended Senate Bill 5, a comprehensive artificial intelligence regulation package that includes significant new oversight requirements for AI companion chatbots and youth interactions with conversational AI services. SB 5 now heads to the Connecticut House, where Governor Ned Lamont's administration has signaled support for the bill's underlying frameworks.

Why It Matters

For AI sex-tech and companion-chatbot operators, the Connecticut bill is the latest signal that the patchwork of state-level safety requirements is consolidating into a recognizable regulatory floor: AI disclosure to users, sexual-content blocks for minors, and crisis-service referral protocols. Connecticut's approach of folding chatbot rules into a comprehensive frontier-AI package matters because it normalizes companion chatbots as just one regulated AI category among many — making it harder for industry to argue these products deserve unique exemption from broader AI safety obligations. The April 21 vote also lands as the federal GUARD Act (S. 3062) and similar federal proposals continue to wind through Congress; states are setting the floor while Washington works.

For the sex-tech and AI-companion industries, the chatbot provisions are the most consequential portion of the bill. Operators of conversational AI services — a category that explicitly includes Replika, Character.AI, Candy.AI, and similar companion platforms — must disclose that the service is AI rather than human if a "reasonable person" would not understand the difference, and must make that disclosure to minors specifically. The bill prohibits AI services from representing themselves as designed to provide professional mental or behavioral health care. It also requires operators to make "reasonable efforts" to detect suicidal ideation or self-harm language and respond with referrals to crisis services such as suicide hotlines or crisis text lines.

The bill's chatbot framework was driven in part by Sen. Saud Anwar (D-South Windsor), who cited the case of a teenage boy who died by suicide after being encouraged by an AI chatbot during floor debate. The lead author, Sen. James Maroney (D-Milford), framed the law as basic consumer protection: "What we're doing is we're putting in important protections. Sometimes these machines get things wrong." Sen. Paul Cicarella (R-North Haven) provided one of the GOP's four supporting votes despite party-line opposition, telling colleagues, "I think that this will do more good than any negative."

Beyond the chatbot piece, SB 5 also regulates "frontier" AI model developers, creates a state AI "sandbox" for technology testing, requires age verification for certain youth social media platforms, and imposes notice requirements on employers using AI for hiring and employment decisions. The age verification provisions sparked the heaviest privacy criticism in floor debate, with some senators questioning whether the late amendments were ready for a vote at all. The amended SB 5 substantially overlaps with provisions in companion bill SB 86 — both bills contain the chatbot oversight requirements, suggesting Connecticut will land on a single statute regardless of which path advances.

Connecticut joins a growing group of states moving to regulate AI companion chatbots in 2026. California's SB 243 took effect January 1; Oregon's SB 1546 and Washington's HB 2225 passed in March; Nebraska's LB 525 was signed by Gov. Jim Pillen on April 14, becoming the fourth state to enact a chatbot-specific safety law. New York, Pennsylvania, Idaho, and Maine all have active companion-chatbot legislation pending. The Connecticut bill differs from the earlier wave by bundling chatbot rules into a comprehensive AI omnibus package rather than passing as a standalone — an approach that could be replicated in other states with active broader AI bills.

On Friday, May 1, 2026, the Connecticut House of Representatives gave final passage to Senate Bill 5 by a 131-17 vote, sending the comprehensive AI regulation package — formally titled the Connecticut Artificial Intelligence Responsibility and Transparency Act — to Governor Ned Lamont's desk. A spokesperson for the governor confirmed Friday that he plans to sign the bill, ending Lamont's two-year resistance to comprehensive state-level AI legislation. The bill becomes law on signature, with phased compliance dates starting in 2027 for most operator obligations.

The May 1 vote followed a deal between Lamont and lead author Sen. James Maroney (D-Milford) that grafted Lamont's preferred regulatory-sandbox and youth social media provisions onto Maroney's underlying AI omnibus. The resulting bill bundles four distinct regulatory regimes: (1) the AI companion-chatbot framework that triggers most directly for sex tech and AI-companion platforms; (2) frontier AI model developer requirements; (3) state regulatory sandbox provisions; (4) youth social media and AI age-verification rules.

For sex tech and AI companion operators, the bill is now operative law in Connecticut on signature. Replika, Character.AI, Candy.AI, and similar platforms must implement: AI disclosure to users where ambiguous, prohibition on representing AI as a licensed mental-health provider, mandatory crisis-line referral for self-harm/suicide content, and a hard ban on minors using chatbots that can encourage self-harm or simulate mental-health treatment. Non-compliance is enforceable as a deceptive trade practice under Connecticut's existing consumer protection statute.

Connecticut becomes the fifth state to enact a chatbot-specific safety law, following California (SB 243), Oregon (SB 1546), Washington (HB 2225), and Nebraska (LB 525). Notably it is also the first to bundle chatbot rules into a comprehensive frontier-AI omnibus rather than passing them as standalone legislation — a structural choice that other states with active broad AI bills (New York, Pennsylvania, Idaho, Maine) are likely to emulate. The May 1 final passage closes a 14-day legislative push from Senate (April 21) to House (May 1) and represents one of the fastest comprehensive-AI bill passages in any US state to date.
