Sleeper + ChatGPT
Yes, you can connect Sleeper to ChatGPT. League Loom is a custom connector that lets ChatGPT read your live Sleeper league, rosters, matchups, standings, and the waiver pool, then answer questions in plain English like best available adds for your team. Sleeper is public data, so all you give is your username, no password. It is fully read-only and free, so ChatGPT can read your league but never makes a single move.
Read your Sleeper roster and scanned the free agent pool. Your RB depth is thin behind an injury, so the top adds lean to backfield value and a streaming WR.
Compared your two flex options against this week's matchups and recent target share.
| Player | Matchup | Proj | Volume |
|---|---|---|---|
| Jaylen Warren (RB) | vs CIN | 12.4 | Steady touches |
| Khalil Shakir (WR) | vs MIA | 10.1 | Slot, soft coverage |
Warren has the safer floor with a clear touch count, while Shakir leans on a friendlier matchup but more variance.
Pulled the live Sleeper standings and points for through this week.
| Team | Record | PF |
|---|---|---|
| Gridiron Goblins | 8-2 | 1,184 |
| Your Team | 7-3 | 1,209 |
| Audible Anarchy | 7-3 | 1,131 |
You sit second in the standings but lead the league in points for, so your schedule has cost you a game or two more than your scoring deserves.

Why League Loom
Most tools make you export rosters or paste screenshots into ChatGPT. League Loom skips all of that: ChatGPT reads your Sleeper league directly from live data, so when you ask for the best available adds it actually scans your real waiver pool and your real roster holes, not a stale copy. Because Sleeper is username-only, there is no password to hand over and nothing for ChatGPT to write back, the connector is strictly read-only.
