Your best lineup, every week

AI Fantasy Lineup Optimizer

League Loom connects Claude or ChatGPT to your live ESPN, Sleeper, or Fantrax roster so it can check your starting lineup and recommend changes before kickoff. It flags any starter on a bye, listed as injured, or tagged questionable, and points to a healthy bench player who could take that spot. You still make the swap yourself in your league app. Nothing gets set or submitted automatically.

Why League Loom

Your best lineup, every week

A lineup recommendation is only as good as the data behind it, so League Loom pulls your actual starting lineup, bench, and live injury and bye status straight from your connected league instead of guessing. Ask for a lineup check and it walks your starting slots one by one, comparing each starter against real roster data to catch problems before they cost you points. Say your RB1 is on a bye this week: League Loom flags it and names the bench running back who's active and worth starting instead. If a wide receiver is listed questionable with a game-time decision, it surfaces that status alongside your other options so you're not caught off guard at kickoff. It can also compare a struggling starter to a bench player who's trending up, so you can weigh a straightforward upgrade. Every recommendation traces back to your league's real slots, bench size, and player statuses, not a generic depth chart, and you still make the final call and set the lineup yourself in ESPN, Sleeper, or Fantrax.

FAQ

Questions

Does it catch byes and injuries automatically?

Yes. League Loom reads live status for every player on your roster, so the AI flags byes, injuries, and questionable tags before your lineup locks.

Can it optimize lineups across multiple leagues at once?

Yes. Connect all your ESPN, Sleeper, and Fantrax leagues and ask the AI to set the best lineup in each from one prompt.

Will it change my lineup for me?

No. League Loom is read-only. It tells you exactly what to start and sit, but you make the actual change in your fantasy app.

Does the lineup check work for any position, or just star players?

It checks every starting slot in your league, including flex, bench, and IR spots as configured in your actual league settings. Whether it's your QB1 or a deep-league flex spot, League Loom reads the same live roster and status data for all of them, not just headline players.

Can it tell me if a player is a confirmed starter in real life before I set my lineup?

No. League Loom surfaces the injury, questionable, and bye status your league platform reports, not outside news or confirmed-starter reports. For game-time decisions, treat its flag as a heads-up to check further, not a final word.

How is this different from my league app's built-in optimal lineup button?

League Loom doesn't auto-set anything. It explains its reasoning in plain language, ranks bench alternatives by your specific matchup needs, and works the same way across ESPN, Sleeper, and Fantrax, so you get one consistent lineup check no matter which platform your leagues use.
