Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier. Category leader. Nothing else is close yet.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
