Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.B-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
