Kai's verdict	B-tier. Still early. Manus is more flexible for less money.	S-tier. If you're on Vercel/shadcn, this is cheating.	B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
