Weaknesses	Slow vs doing it yourself Breaks on complex auth flows $200/mo gate	Expensive Best for well-scoped tasks Not for solo hobbyists	Pricey for casual use Fiction-only focus — not for business writing	Aesthetic ceiling below Midjourney Less style variety
Kai's verdict	B-tier. Still early. Manus is more flexible for less money.	A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.	S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.	S-tier for text-in-image. Use this for posters, Midjourney for art.
