Kai's verdictA-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for designers. The only one that takes vectors seriously.
