Best for	Replacing Google for any question where you want a cited answer in seconds.	Breaking news, live event tracking, users already on X.	Long writing, code, careful thinking, documents over 50 pages.	Developers who want an agent, not autocomplete. Large refactors, tests, docs.

Weaknesses	Not a general chatbot Answers can be shallow on complex topics	Writing quality trails Claude/ChatGPT Political bias debates Ecosystem is just X	Image generation is weak No native web search on all tiers	Terminal-based — learning curve Can't be used without Claude subscription
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 for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
