A quick wizard finds your leagues and lets you pick your team in each. No API keys.
Ask about your roster, waivers, matchups, and more — in plain language, across every league.

Most AI fantasy tools only answer from whatever you paste in, which goes stale fast. League Loom pulls your actual ESPN, Sleeper, or Fantrax roster and matchup live, and it's one of the only connectors that also supports Fantrax NFL leagues.
