Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.A-tier for creators training custom looks. B-tier for general use.S-tier. Category-defining UX. If you take notes in meetings, switch this week.
