StatsDeck is a fantasy football analytics brand that connects Claude, Anthropic’s AI assistant, with NFL data and information from a user’s fantasy league. Its free beta custom connector supports leagues on Sleeper, ESPN, and Yahoo, bringing current rosters, scoring rules, lineups, matchups, and standings into conversations with Claude. Users can also explore players, matchups, draft strategy, and waiver ideas without connecting a league.

StatsDeck helps fantasy managers assess rosters, make start-or-sit decisions, compare trades, review matchups, and consider waiver options. It can also create visualizations of rosters, matchups, and trades, with a deeper analysis mode available for more detailed questions. League information is retrieved live from supported platforms, while NFL statistics come from nflverse, with historical data dating back to 2012. The service includes player production, snap counts, depth charts, schedules, and defensive matchup information, refreshed on different schedules. Injury details draw on official NFL reports, platform status flags, and sourced reporting, with dates and sources provided. StatsDeck also offers a Slack community and email support for questions and feedback.
