Kai's verdictB-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
