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.A-tier if you already pay Gemini. B-tier standalone.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
