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 for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.B-tier. Useful for first drafts. v0 is the better bet for shipping code.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
