California SB 243 — AI Companion Safety Act
Jurisdiction: California, USA
In force: · Last checked:
Summary
California SB 243 is the first US law targeting the 'continuous anthropomorphic relationship' created by AI companion apps. In force since 2026-01-01, it defines the app operator (not the underlying model provider) as solely responsible for minor-safety obligations. Key mandates include clear AI-nature disclosures, 3-hour break reminders for minor users, a ban on randomized-reward (casino/gacha) mechanics for minors, and evidence-based crisis-detection protocols that redirect users to crisis hotlines. The law creates a private right of action: $1,000 minimum per infraction.
