Kai's verdictS-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.B-tier. Still early. Manus is more flexible for less money.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
