1
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.

replayed pick outcomes

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."

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.

POWERED BY GOOGLE GEMINI

A frontier-class model writes every word of it.

Every "why" behind a Pylon recommendation is written live by Google Gemini — the same model family behind Google Search's AI Overviews and Workspace. It reads fast enough to answer before the clock runs out, and it's kept on a short leash: Gemini narrates the algorithm's own math — it doesn't get to make any up.

Frontier-grade reasoning
Turns VORP, tiers and survival math into a sentence you'd actually say out loud at the table.
Answers before the clock runs out
Cached per pick, so unlimited Pro insights never slow down a live snake draft.
Grounded, never invented
It only narrates the algorithm's own top eight — no re-ranking, no hallucinated stat, ever.
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.

Reliability diagram — survival predictions
Dot size = sample count. Perfect calibration follows the diagonal.
