| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for academic research. Nothing else comes close for systematic reviews. | B-tier. Still early. Manus is more flexible for less money. | A-tier. Best for cinematic image-to-video. Pair with Runway for coverage. |
