Enter your Sleeper username and the Front Office finds your leagues (pick one if you're in several). Scoring, roster spots and format — dynasty, keeper or redraft, 1QB or Superflex — are read straight from your league, so there's nothing to set up.

What you get

• War Room — this week's matchup preview with win probability, your lineup, usage movers, and team rankings
• League — team performance (all-play, luck, lineup efficiency), rankings by position, injury report
• Scouting — usage board for every player: snaps, target share, expected points
• Waivers & Picks — the best available players, plus waiver history: which pickups actually produced
• Draft History and a Trade finder / builder

Where the data comes from

• Sleeper — your league, rosters, matchups, transactions, player stats, projections and injuries
• FantasyCalc — player and pick trade values (dynasty or redraft to match your league)
• ESPN — live NFL scores and kickoff times

Everything loads live in your browser from those public sources. No account, nothing saved on a server, and your Sleeper league is only read, never changed.

The Anthropic API key is optional: it unlocks an AI-written trade analysis for the most thorough read on a deal. Everything else works without it. If you add one, it's sent only to Anthropic, kept in this tab, and never stored.
