Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for open-source model APIs. The default in this space.A-tier for social/casual. B-tier for serious work. Good entry point.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.
