Kai's verdictA-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier. Best free agentic option in VS Code. Use with Claude for best results.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
