Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.A-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier if you already pay Gemini. B-tier standalone.S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.
