Why League Loom
ChatGPT cannot see a private fantasy league on its own. It does not know your roster, scoring rules, or waiver pool, and screenshots become stale as soon as the league changes.
League Loom closes that gap by connecting ESPN, Sleeper, or Fantrax through OAuth with Dynamic Client Registration and PKCE. Ask for the top available wide receivers and it checks your league's actual free-agent pool.
Ask about a Sleeper FAAB budget or playoff format and it reads the relevant league data instead of guessing. All current tools retrieve or analyze data.
