| Kai's verdict | S-tier for builders. The right primitives. What Kai is built on under the hood. | S-tier for aesthetics. If you care how it looks more than how it's made, this wins. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. |
