Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.B-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.
