Kai's verdictA-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.B-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.
