| 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. | A-tier. Best for cinematic image-to-video. Pair with Runway for coverage. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. |
