Start on paper. No card, no API key.

Paper bots copy the same traders under the same rules as live ones and record what would have happened. Nothing is at stake, so there's nothing to connect yet.

Email address I understand Taildraft is software, not advice, and that copying a trader can lose money.

We send a sign-in link instead of asking you to pick a password. One email, no newsletter.

Step 1 of 5

Pick traders to follow

Ranked by what they returned per dollar on bets we can copy — full-game favourites, held to the result, losing bets included. Pick up to three to start.

These records are each trader's own history after an estimated 3% in costs. A record is evidence about the past, not a forecast.

None selected

Set your limits

These apply to every bot you start, live or paper, and you can change them per bot later.

Step 3 of 5

Ready to run on paper

Check it over. Paper bots start watching for new bets within a minute of finishing here.

Expect quiet stretches. Polymarket US doesn't list every game or offer every bet type, so only a fraction of what your traders do can be mirrored.

Step 4 of 5

Your paper workspace is running

We'll email you a daily summary at 9am. Watch for a week before you think about real money — a handful of games tells you nothing.

When you're ready for real money: you'll connect Polymarket US with an API key that can trade but cannot deposit, withdraw or transfer. Here's what that takes, so there are no surprises.

Connecting Polymarket US, later

In Polymarket US, open Settings → API keys and create a key with trading permission only.
Copy the key and secret. Polymarket shows the secret once.
Paste both into Taildraft under Account → Connection. They're encrypted at rest and we show only the last four characters afterwards.
Promote a bot with Go live. You'll type REAL MONEY to confirm, and we'll show you whether that bot has cleared 30 settled games with a positive record first.

Don't paste a real key into this prototype. This page is a design preview with no account behind it. The field below is deliberately inert.
