Kai's verdictS-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Best free agentic option in VS Code.
