Kai's verdictB-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.A-tier. Best for teaching a kid to code in 2026.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
