Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-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 for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
