The web connected the world's documents. Google organized them. AI now speaks for them. Each shift created a company that owned the layer underneath.

This one skipped a layer. AI absorbs the world's knowledge into models that can't tell you where any of it came from. And the source is the whole reason you could trust it.

QuarterMill is that missing layer. We're working on how knowledge gets proven, trusted, and preserved at scale. Not a better model, the layer of trusted knowledge the models sit on top of.
