Kai's verdictA-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.S-tier for text-in-image. Use this for posters, Midjourney for art.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
