Weaknesses	Less agentic than Cursor/Claude Code Model quality varies	Not a general chatbot Answers can be shallow on complex topics	Overlaps with general chatbots Workflow setup takes time	UX is rough for English speakers Queue times
Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	A-tier for ops automation. B-tier for simple copy (use Claude).	A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
