Kai's verdictA-tier in its niche. The only one that actually gets emotion right.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.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
