Kai's verdict	S-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 multilingual video. If you sell courses or speak at events, this is a cheat code.	A-tier. No reason not to use it if you're on Figma. Not worth switching for.
