Kai's verdictA-tier in its niche. The only one that actually gets emotion right.S-tier inside Photoshop (Generative Fill). B-tier standalone.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.
