Kai's verdict	S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.	A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.	B-tier. Still early. Manus is more flexible for less money.	S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
