Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier. Best free agentic option in VS Code. Use with Claude for best results.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Niche but beloved. If you've outgrown Notion, try this.
