Kai's verdictS-tier for speed. When latency is the product, start here.A-tier for social/casual. B-tier for serious work. Good entry point.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
