Kai's verdictA-tier for designer-led sites. S-tier if animations matter.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.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
