Pose any resolvable question — a price, an election, a supply chain, a storm track.
The engine decomposes it, weighs the evidence, and returns a distribution — not a hot take.
Wire probabilities into dashboards, hedges, and plans. Re-weigh automatically as the world moves.
Probable worlds
Every question resolves into a family of worlds. We keep them all on the table — each one carrying exactly the probability it has earned.

“We stopped arguing about opinions and started arguing about distributions. That alone paid for it.”
