PolySmarter

Three layers of Polymarket intelligence: resolution rules, information updates and real execution costs.

Understand the contract. See what changed. Estimate a hypothetical fill. PolySmarter is a read-only research and market-analytics extension for Polymarket. It brings resolution rules, recent market context and live-order-book execution analysis into one Chrome side panel, reducing the need to switch tabs, do manual calculations or repeatedly re-check the same market details. Resolution and rules Start with the condition that actually resolves YES. PolySmarter presents the current YES condition, deadline, resolution source and key exceptions, and shows rules-change status when available. The full market rules and designated resolution source remain authoritative. Market changes and information context Understand what has changed recently. PolySmarter summarizes recent price and trading activity and, where data is available, adds context from inferred trade direction, large trades, public information, related outcomes or related markets. Timestamps, coverage states and methodology are shown with the analysis so unavailable or stale data is not presented as current fact. Hypothetical execution analysis The headline price is not necessarily the price available for your size. Select YES/NO, BUY/SELL and a hypothetical amount, and PolySmarter uses the currently visible order book to estimate average fill, worst fill, price impact/slippage, fees, all-in cost, effective breakeven and visible depth consumed. Where supported, you can also inspect the maximum hypothetical size that stays within a selected cost limit and create a Watch for price, spread, depth, breakeven or rules changes. Free and Pro Free includes core resolution, market-change, price and basic hypothetical execution analysis. An optional Pro subscription provides larger or custom-size analysis and additional trade, participant and public-wallet context. The functionality currently shown in the extension is the authoritative feature set. Read-only boundaries PolySmarter does not connect to a wallet; read a Polymarket account, balance, positions or order history; or place, route, execute, cancel or manage orders. PolySmarter does not provide probability forecasts or Buy/Sell instructions and is not investment, financial, legal or tax advice. Some analytics depend on public-data coverage; when coverage is insufficient, the extension shows an unavailable, partial or explanatory state rather than inventing a replacement value. Use PolySmarter in Chrome's native side panel or a floating panel, switch between Chinese and English, and choose dark, light or system theme.
