Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier if you're on Mac. The fastest way to get AI answers without context-switching.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.
