Exploratory tools for prediction markets.
We make the tools. You make the calls.
Picks and shovels for the prediction-market era — live data, calibration history, and market context across Kalshi, Polymarket, and Manifold. Built by a quant for explorers who want to look closer, not be told where to dig.
Three things, all free, no signup.
We don’t hide our methodology behind a paywall. The tools that make us money sit on top of a transparent base anyone can inspect.
What’s hot.
Live market activity across Kalshi, Polymarket, and Manifold. Sort, filter, and pin what matters — your view, saved between sessions.
Browse the feed →What we’d grade A.
Quality scoring on open markets: bracket-edge margin, liquidity, and forecast confidence — with every input cited and every model dated.
See methodology →What we’ve predicted.
Every forecast we’ve published, locked at publish time, with the outcome attached. We grade ourselves in public — reliability curve and all.
See the scoreboard →What’s behind Pro.
Pro removes the lag, adds alerts and the deeper tools, and supports the work. We make money on subscriptions — not on revshare, not on your data.
