Kai's verdictA-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.B-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.B-tier. Still early. Manus is more flexible for less money.
