Character.AI Bans Minors From Open-Ended Chats as Tragedy and Lawsuits Force Change

Per The Guardian and Fortune, Character.AI announced on October 29, 2025 that users under 18 would be barred from open-ended conversations with its AI characters, with age-verification tools introduced. The move followed lawsuits alleging its chatbots encouraged self-harm or were linked to teen deaths.

It was the first time an AI companion app voluntarily amputated a core feature for minor safety — against a backdrop of U.S. lawmakers moving to bar minors from AI companions and mandate age verification.

The case became the defining example of AI ethics meeting child safety: when AI products enter emotional territory, the tension between guardrails and growth lands in the spotlight.

Behind the Amputation: Business Model Meets Risk Head-On

What gives the move its weight is that open-ended chat is the lifeblood of AI companionship: retention curves driven by long sessions, high frequency and emotional stickiness underpin these products' valuations — and minors are among the stickiest users. Voluntarily cutting that segment under the pressure of lawsuits and regulatory hearings amounts to admitting the risk had outgrown the business logic. The spillover was immediate: OpenAI rolled out parental controls and age-prediction mechanisms in the same period, and across the 500-million-user companion-app market (see our coverage), age verification is shifting from optional to table stakes.

The regulatory chain reaction is equally clear: states and Congress are advancing bills restricting minors' access to AI companions — and with federal AI regulation otherwise absent (see our SB 1047 coverage), child protection has become the one AI issue both parties can agree to legislate.

Our Take

Character.AI's choice drew an industry line: for emotional AI products, risk is no longer a PR problem but an architecture problem — age tiers, crisis intervention and session-time controls must be designed in, not patched on. The lesson for founders and investors is just as blunt: growth stories in the companionship lane must reprice regulatory risk, and 'high stickiness' — once a fundraising selling point — has become a liability wherever minors are involved.
