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
AI Dungeon
- Genuinely open-ended, with no fixed script limiting where a story can go
- Can produce surprising and memorable creative moments
- Large library of community-created scenarios to start from
- Story coherence and quality vary significantly session to session
- Requires active steering from the player to stay on track
- Not a substitute for a polished, professionally written narrative game
