Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.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.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
