Kai's verdictA-tier. Close second to Cursor. If $5/mo matters, start here.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-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.
