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.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier. If you're on Vercel/shadcn, this is cheating.
