Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.A-tier. Best for teaching a kid to code in 2026.A-tier. Best free agentic option in VS Code. Use with Claude for best results.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
