Kai's verdict	B-tier. Still early. Manus is more flexible for less money.	B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.	S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.	A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
