Kai's verdictS-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.A-tier for creators training custom looks. B-tier for general use.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
