Kai's verdictS-tier for text-in-image. Use this for posters, Midjourney for art.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.
