## Overview

PolySensei is a free Chrome extension that adds a layer of professional-grade data to Polymarket, the prediction-market exchange. Rather than replacing Polymarket, it embeds into the same page: your theme, the same charts, the same buy button — but with whale flow, smart-money positioning, true slippage, fair value and full order-book depth layered on top the moment a market loads.

The signals are computed live from public Polymarket and on-chain data. Whale flow comes from the global trade feed, so net big-money buying shows up before the price moves. Smart money scores every wallet on an outcome by how many of its past markets resolved in its favour. True fills come from Polymarket's own CLOB order book, so slippage and resting walls are measured rather than guessed, and fair value compares a model price against the market price to express your edge in cents. On sports markets it also pulls live scores and vig-stripped Vegas lines, and it flags markets that resolve on UMA so you trade resolution risk knowingly.

The extension is non-custodial: you sign every order in your own wallet, and no account, signup or email is required. It charges no added fees — you pay exactly what you would trading directly on Polymarket — and it may earn through Polymarket's builder program on routed volume. A gamified Sensei Points system with belt ranks adds status and perks inside the app, with no cash value and no token.

## Pricing & Plans

PolySensei is free to install and use, with no subscription and no fees added to your trades. It earns through Polymarket's builder program on the volume routed through it, so your execution price matches trading directly on Polymarket. Sensei Points and belt ranks are in-app status only, with no cash value or token.

## Key Features & Capabilities

- **Whale flow tracking:** Big trades are tagged buy or sell and summed live, showing net money flow into an outcome before the price catches up.
- **Smart-money records:** See the top holders on each outcome, scored by how often they have won in the past, and whether they are currently up or down on this market.
- **Entry, slippage and Kelly sizing:** Enter an amount and your estimated probability to see your true fill price, real slippage, exact payout and a Kelly-optimal stake before you click buy.
- **Fair value and edge in cents:** A model fair value is compared against the live market price and shown as your edge in cents, so you can spot underpriced sides at a glance.
- **Command center and resolution radar:** An exchange-wide board flags mispricings, whale activity and UMA resolution risk across Polymarket markets, with filters to narrow the noise.

## Primary Use Cases

- **Size trades without overpaying (Prediction-market trader):** Check the entry calculator before committing: see your real average fill price, slippage, payout and a Kelly-optimal stake so you never overpay on a thin book.
- **Follow the sharps (Trader following smart money):** Watch net whale flow and the win rates of top holders on each side, then align with the side proven winners are actually backing before the price moves.
- **Scan for mispriced markets (Analyst / researcher):** Use the command center to scan every market for mispricings and UMA resolution risk, and read live sports or crypto context next to the price.

## Strengths

- Free, with zero fees added to your trades
- Non-custodial — you keep your keys and sign every order
- Combines whale flow, smart money, true slippage, fair value and order-book depth in one overlay
- No account or signup required and it adopts Polymarket's own theme
- Signals are prefetched and feel native, with no spinner between you and the trade

## Limitations

- Currently tied to a single platform — it only works on Polymarket pages
- Requires being a Polymarket trader to get any value, so it is niche by design
- Many signals depend on live order-book and on-chain data, so quality of read depends on market liquidity
- It is a browser extension, so mobile trading is not covered
