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.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
