Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
