Kai's verdictA-tier for real-time. B-tier for everything else. Worth checking when news breaks.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.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.
