Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Bet on this one — the Sparkpage format is genuinely new.A-tier if you already pay Gemini. B-tier standalone.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.
