Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.B-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
