Weaknesses	Best for shadcn stack Iterating can be fiddly	Slow vs doing it yourself Breaks on complex auth flows $200/mo gate	Aesthetic ceiling below Midjourney + Ideogram Text rendering worse than Ideogram No fine control	Developer-only You build the UI
Kai's verdict	S-tier. If you're on Vercel/shadcn, this is cheating.	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 builders. The right primitives. What Kai is built on under the hood.
