Kai's verdictA-tier. Best for teaching a kid to code in 2026.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.B-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.
