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
ChatGPT
- Largest user base and ecosystem of any AI assistant, with the most third-party integrations
- Genuinely broad capability across writing, coding, research, and file analysis
- Custom GPTs allow tailoring the assistant to specific repeated tasks
- Frequent model updates keep it competitive on raw capability
- Free tier has usage limits and access to a lower-tier model than paid plans
- Can produce confident-sounding but incorrect information, especially without browsing enabled
- Breadth can mean less depth than a tool purpose-built for one specific workflow
- Data usage and training policies require attention for sensitive or regulated work
