Kai's verdictB-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.S-tier for local inference. If you care about privacy or want to tinker, install this today.A-tier. Best for fast prototypes. Competitive with Lovable — try both.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
