Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier in its niche. The only one that actually gets emotion right.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
