Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for designers. The only one that takes vectors seriously.A-tier in its niche. The only one that actually gets emotion right.S-tier. If you're on Vercel/shadcn, this is cheating.
