Kai's verdictS-tier for teachers. If you teach K-12, start here this week.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
