Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
