Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier in the agent category. The first one I'd give to a non-technical friend.
