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.S-tier inside Photoshop (Generative Fill). B-tier standalone.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.
