Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for teachers. If you teach K-12, start here this week.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.
