Weaknesses	Terminal-based — learning curve Can't be used without Claude subscription	Pricey for casual use Fiction-only focus — not for business writing	Not a general chatbot Answers can be shallow on complex topics	Stricter content policy than competitors Hit-or-miss on complex motion Text-in-video still struggles
Kai's verdict	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
