Four decisions

It does not predict better. It decides better.

Draft

Who do I take here, and what is he worth to my roster?

The snake draft screen on a phone: your next pick is 24, 23 picks away, the players likely gone before it, and the best value remaining at RB.
Auction

What is my walk-away price on this player, right now?

A Sleeper auction running on a phone in the browser: the room's remaining budgets, the player you tapped, and a BID verdict with a walk-away price.
Waivers

Which claim is worth the money, and how much?

The waiver screen on a phone: a MUST ADD call with rest-of-season points, breakout and bust odds, and a bid ladder.
Lineup

Who starts, against the roster I actually play this week?

The lineup screen on a phone: week 5, 43% to win, the nine starters laid out on the field with each one’s projected points.

We don't out-project the experts. Nobody does. We built a projection model, tested it properly, and lost: 0.583 against consensus at 0.623. So the forecast isn't what's for sale. Everyone in your league already has the same numbers. What's for sale is the decision layer on top — walk-away prices, win-probability lineups, ranked claims. The edge is thin, and it is measured.

Questions

What do I have to connect?

An ESPN or Sleeper league, usually just its id. Sleeper needs no extension. ESPN needs the Chrome extension only for live draft rooms; everything in-season runs in the web app. Yahoo, no — and not this season. If Yahoo is your only league, leave your address above and don't pay. Storing it is all I promise today.

How many leagues?

A Season licence runs one league. Add another for $29 on the same key, or Multi-League runs every league you connect and adds the Friday refresh and the cross-league screens.

Can I try it first?

Yes. The practice room is the whole draft engine, free, no account, no limit. A licence is per league; full refund within fourteen days, or until you attach a live draft room, whichever comes first.

You're one person. What if you stop?

Then you're owed a refund for the unused season and you get it. The method and the backtest are published, so the reasoning outlives the service either way.

Why publish the losses?

Because a tool that only shows its wins can't be checked, and an edge this thin is indistinguishable from noise unless you can see the runs where it vanished. All of it is here.
