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.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.B-tier. Still early. Manus is more flexible for less money.
