Kai's verdictA-tier. The most interesting spreadsheet in years. Great for ops dashboards.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.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.
