Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-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.
