Pros & Cons

Character.ai

  • Pioneered and remains a leading, widely recognized AI companion chat platform
  • Contextual moderation represents a more sophisticated approach than simple keyword filtering
  • Real age-verification enforcement reflects genuine effort to address regulatory concerns
  • Lost approximately 8 million users in 2026 following the stricter filtering and age-restriction changes
  • Users under 18 no longer have open-ended conversation access, limited instead to Stories mode
  • Ongoing regulatory pressure across the AI companion industry means further changes are plausible
