Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.S-tier for text-in-image. Use this for posters, Midjourney for art.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.
