Pylon
About Pylon
Pylon is a live draft co-pilot designed specifically for Sleeper fantasy football leagues. It models the probability that each player on the board will still be available at the user’s next pick, presenting this data alongside value tiers, positional need multipliers, and projected points. The tool recomputes these metrics every five seconds based on the live draft board and user-defined strategy. Recommendations are accompanied by plain-language explanations generated by Google Gemini, which narrates the reasoning without altering the rankings. Users can override suggestions after reviewing the underlying data, including survival percentages and ADP comparisons from multiple sources. The interface displays a live board with survival probabilities for each player and run alerts for positional trends. After the draft, Pylon provides a recap grade that blends projected points against league-specific scoring with value-hit analysis. The system includes a scouting report feature that aggregates real pick history across a league’s history to profile each manager’s drafting patterns.
