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.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.S-tier for text-in-image. Use this for posters, Midjourney for art.
