Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.A-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.
