Weaknesses	Not a general chatbot Answers can be shallow on complex topics	Writing quality trails Claude/ChatGPT Political bias debates Ecosystem is just X	Terminal-based — learning curve Can't be used without Claude subscription	Image generation is weak No native web search on all tiers
Kai's verdict	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	A-tier for real-time. B-tier for everything else. Worth checking when news breaks.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
