Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.S-tier in its category. The first AI music tool I'd actually listen to.S-tier. If you're on Vercel/shadcn, this is cheating.
