Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier in its category. The first AI music tool I'd actually listen to.A-tier. Genuinely different vibe from Suno — worth trying both for a month.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
