Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.
