De'Von Achane RB MIA
Last back on the board with a true bellcow role and pass-game volume. At +9 over ADP he's the clearest value at 3.03, and only 6% to survive to 4.10.
EDGE SCORE

Drake London WR ATL
Last Tier 2 WR left and the tier breaks after him. A WR run is live, so waiting costs you the tier, not just the player.

Draft advice is either generic or unfalsifiable.

Half of it is a static ranking everyone else at your table is also staring at. The other half is an AI score you can't audit, from a tool that never tells you whether it was right. Neither answers the only question that matters on the clock: can I wait on him?

HOW IT WORKS

The algorithm decides. The AI only explains.

01
The model computes

VORP, value tiers, positional need multipliers and a survival probability for every player on the board, recomputed against your real draft table every five seconds.

Google Gemini narrates it

A frontier-class model reads the top eight the algorithm already ranked and writes them up in plain English. It never re-ranks, never invents a stat, never surfaces a player the model didn't.

"Take Achane now: 6% to make it back, and the tier breaks after him."

03
You make the pick

Every number behind the recommendation is on screen, so you can overrule it on purpose, instead of guessing what the black box meant.

PROOF

The model grades its own homework.

Every finished draft is replayed and every survival prediction checked against what actually happened. When Pylon says 70%, players came back 70% of the time. Most tools can't show you this, because they never look.

Measured on Pylon's own logged predictions. Every account gets the same dashboard for its own drafts, so you can check ours against yours.

FAQ

Questions before you type your username.

Do I need to give Pylon my Sleeper password?

No. Sleeper's read API doesn't use one: your username is all Pylon needs to find your leagues and drafts. There's no password field anywhere in the product.

What's a "guest account"?

Typing your username on this page creates a real account with no password, so your leagues, watchlist and draft history are saved when you come back. Add an email later if you want to sign in from a different device. Skip it and it still works.

What happens on September 1 if I don't add a card?

Nothing breaks. Your account drops to Free: one draft, the same algorithm, and survival odds on your top recommendations. Add the season pass whenever you want the rest back.

Does it handle keeper and dynasty leagues?

Yes. Sleeper marks keeper picks at the round they were kept in, scattered through the board instead of lined up at the front, and Pylon's on-the-clock logic accounts for that instead of miscounting who's actually up.

What about auction drafts?

Not yet. The survival model and recommendations are built around one pick being on the clock, which auction drafts don't have. Snake and linear drafts, standard and keeper leagues, any scoring format, all work today.

What does Pylon actually read from my Sleeper account?

Only what Sleeper already makes public: your leagues, rosters, users and draft picks. Nothing is written back to Sleeper, and nothing is shared with your leaguemates unless you hand them a link yourself.

Do I have to pay to try it?

No. Your first draft is free with no card, covered by the Free plan above. Every Pro feature, including the season-long optimizer, is also free for everyone through September 1.
