Kai's verdictA-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.S-tier for teachers. If you teach K-12, start here this week.S-tier for designers. The only one that takes vectors seriously.
