Connect ESPN, Sleeper, or Fantrax to Claude, ChatGPT, or another AI tool, then ask about rosters, start/sit calls, waiver pickups, trades, drafts, standings, and matchups. Every answer uses your live league data, and the connector is free.
ESPN, Sleeper, and Fantrax across NFL, NBA, MLB, and NHL (ESPN also covers WNBA, and Fantrax adds more). The capabilities page has the full provider and sport matrix.
Pick the use case closest to your league, open it, and follow the two-minute connection steps. Add one connector URL, link your league once, and start asking. Every tool available today retrieves or analyzes data, so League Loom cannot change your lineup or your account.
