Kai's verdictA-tier for creators training custom looks. B-tier for general use.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.
