| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for solo + free. The best free option, hands down. | A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead. | B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency. |
