Kai's verdictB-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.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.S-tier in the agent category. The first one I'd give to a non-technical friend.
