| Kai's verdict | B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic. | A-tier for its niche. Different use case than Suno — SFX and loops, not songs. | S-tier for academic research. Nothing else comes close for systematic reviews. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. |
