Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.A-tier for designer-led sites. S-tier if animations matter.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
