Player-prop entries, sized for you

Every entry sized to your bankroll. Every number checked against the record.

Proppi suggests entries for PrizePicks, Underdog and Betr, prices each one at the platform’s own payout, sizes the stake to your bankroll and daily limit, then grades every leg afterwards so you can see how the model really did.

Entries can lose the full stake. Chances and expected value are model estimates, not promises.

How it works

Price it. Size it. Grade it.

  1. 01

    We price it

    For each prop the model estimates a hit chance, then compares it with what the platform pays. The gap, if there is one, is the expected value. It is an estimate, never a promise.

  2. 02

    You decide

    Every suggested entry arrives with a stake sized to your bankroll and your Kelly fraction. Accept it, change the stake, or skip. Nothing is placed for you, and you cannot accept past your daily limit.

  3. 03

    We grade it

    Every entry is graded leg by leg after the games, wins and losses alike. A chart then shows how far the model’s predicted return has been from the return you actually got.

The product

Your bankroll and the model’s honesty, side by side.

Model honesty

Sample data

Each dot is a bucket of past entries: the return the model predicted against the return that actually came back. Under the dashed line means the model promised too much.

In this sample, actual return ran 3.4 points below the prediction. We show you that instead of hiding it.

Built around limits

Playing smaller is a feature.

  • A daily limit you set. Accept switches off when you reach it.
  • Stakes from a Kelly fraction you choose, so a cautious setting means smaller stakes.
  • Losses stay on the record. Every graded entry shows each leg, hit or miss.
  • No promises. Any entry can lose its full stake. Only play with money you can afford to lose.

Straight answers.

No. Proppi suggests entries and sizes them. You place them yourself on the platform, and you can always skip.
