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 overall, A-tier if GDPR/data residency matters. Solid backup option.S-tier. If you're on Vercel/shadcn, this is cheating.
