Kai's verdictA-tier. Genuinely different vibe from Suno — worth trying both for a month.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for builders. The right primitives. What Kai is built on under the hood.A-tier. Best free agentic option in VS Code. Use with Claude for best results.
