Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier in its category. The first AI music tool I'd actually listen to.S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
