Kai's verdictS-tier. Category-defining UX. If you take notes in meetings, switch this week.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.
