Kai's verdictB-tier. Still early. Manus is more flexible for less money.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.S-tier in its category. The first AI music tool I'd actually listen to.
