Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.A-tier for non-native English speakers.
