Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
