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.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for teachers. If you teach K-12, start here this week.
