Character.AI
Roleplay and companion focus, not a general assistant. Massive Gen-Z user base. Voice calls with characters. Different intent than chat-AI competitors.
Microsoft Copilot
Tightest M365 integration (Word, Excel, Teams, Outlook). Free GPT-5 in Bing Chat. Slightly weaker on benchmarks than ChatGPT due to safety tuning.
