Your ESPN league, answered by AI
League Loom connects your ESPN fantasy league to ChatGPT, Claude, and other AI tools so you can ask start/sit, waiver, trade, and matchup questions in plain language, using your real roster instead of guesswork. Public leagues need nothing to connect; private leagues authenticate with two browser cookies (espn_s2 and SWID) instead of your ESPN password. It covers NFL, NBA, MLB, NHL, and WNBA, and works whether you run one ESPN league or several. Read-only and free.
Close call at flex, but the matchup and volume tilt one way.

Why League Loom
League Loom reads your ESPN league through ESPN's own fantasy data, so Claude, ChatGPT, and other AI tools can answer start/sit, waiver, trade, and lineup questions grounded in your actual roster instead of a stale copy-paste or a guess. Public ESPN leagues need no credentials at all. Private leagues authenticate using your own espn_s2 and SWID cookies, the same two values your browser already uses to keep you logged in to ESPN, entered once and sealed into your own encrypted connection. League Loom never sees or stores your ESPN password, and nothing is shared across users. Because it's read-only, it can pull your standings, matchups, and the ranked waiver wire, but it can never submit a lineup change, propose a trade, or claim a player on your behalf. A real ESPN manager might ask it to compare two flex options before Sunday, check whether anyone on their bench is hurt or on a bye, or get a plain-language recap of their league's scoring and playoff rules. It works the same way across NFL, NBA, MLB, NHL, and WNBA, and free the whole time.
FAQ
No password ever. Public ESPN leagues need nothing. For private leagues, you paste two browser cookies (espn_s2 and SWID) once. They're sealed into your own encrypted connection and never stored on a server.
League Loom reads ESPN leagues across NFL, NBA, MLB, NHL, and WNBA. Connect several ESPN leagues, or mix in Sleeper and Fantrax, and ask about them all at once.
No. League Loom is read-only. It answers questions about your league but never sets lineups or makes moves.
Yes. League Loom can connect several ESPN leagues, and you can even mix in Sleeper or Fantrax leagues alongside them. Once connected, you can ask about any of your teams by name, or ask the AI to check across all of them at once.
Yes. Alongside NFL, NBA, MLB, and NHL, League Loom reads ESPN WNBA leagues too, covering rosters, standings, matchups, and the available-player pool the same way it does for other sports.
ESPN's private-league cookies can expire or change if you log out or ESPN resets your session. If that happens, League Loom's connection to that league stops working until you paste in fresh espn_s2 and SWID values, which takes about a minute.
