Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier for teachers. If you teach K-12, start here this week.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
