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 inside Photoshop (Generative Fill). B-tier standalone.S-tier for open-source model APIs. The default in this space.
