Kai's verdictA-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.B-tier. Still early. Manus is more flexible for less money.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.B-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.
