Weaknesses	Best for shadcn stack Iterating can be fiddly	Pricey for casual use Fiction-only focus — not for business writing	Slow vs doing it yourself Breaks on complex auth flows $200/mo gate	Can feel overwhelming for non-coders Expensive at scale
Kai's verdict	S-tier. If you're on Vercel/shadcn, this is cheating.	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.	S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
