Kai's verdictA-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier. Category leader. Nothing else is close yet.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
