Getting started

RulesWatch keeps a copy of the rules of every Polymarket and Kalshi market that trades, and shows you every edit to them. Here's how to use it in five minutes.

1. Find a market

Press Ctrl K (or /) anywhere and type a few words of the market's title, or a Kalshi ticker. Or browse the markets by category, volume and end date. Each market page shows the Yes price over time with every edit marked, and every version of the rules.

2. Read an edit

On a change page, removed words are struck through in red and added words are in green. Switch between inline and side by side; press "Show unchanged text" to read the whole rules. Above the diff: when it happened (the edit window) and the Yes price before and after.

3. Watch what you hold

Press Watch on any market or change page, or paste a market link on the watchlist. Watched markets are checked every 5 minutes. One market is free; Pro removes the limit and can follow your Polymarket wallet.

4. Choose where alerts go

On alerts, add a Discord channel or a webhook. Each one gets a test message right away. Your private RSS feed works without any setup. See alerts for the details.

5. Open it elsewhere

There's no account. In settings, copy your private link or add a passkey, then use it on your other devices. With Pro, your license key works too.
