| Kai's verdict | B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic. | S-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. | S-tier inside Photoshop (Generative Fill). B-tier standalone. |
