Kai's verdictB-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.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.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
