Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.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.
