Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.B-tier. Still early. Manus is more flexible for less money.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
