Kai's verdictA-tier. The most interesting spreadsheet in years. Great for ops dashboards.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.S-tier for text-in-image. Use this for posters, Midjourney for art.
