Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.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.
