| Kai's verdict | S-tier infrastructure. The one platform every AI dev eventually uses. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | B-tier. Still early. Manus is more flexible for less money. | S-tier for academic research. Nothing else comes close for systematic reviews. |
