Kai's verdictA-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier. Granola is better UX but Otter works everywhere.
