- Voice calls feel surprisingly natural compared to other AI voice products

Cons
- Pro at $19.99/month is expensive for a chatbot companion app
- Factual accuracy is poor — not designed for informational queries at all

- Ethical concerns about emotional dependency on AI companions persist
- Controversial content policy changes in 2023 shook user trust significantly
DeepSeek

Cons
- Chinese ownership raises legitimate data sovereignty and privacy concerns for business use
- General writing quality is good but still trails Claude and ChatGPT for nuanced English prose
- Service availability has been spotty — major outages hit during the January 2025 hype wave
