Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.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.
