Hi, I'm Joey. I built Dynasty Seer because every dynasty tool I used answered "What is this player worth?" and none answered the question I actually had: "What will this guy in my league say yes to?"

In a dynasty league you trade with the same eleven people for years. So Dynasty Seer reads your Sleeper league's whole history and builds a scouting report on each owner: who sends offers and who waits, what they overpay for, when they sell, and how to open a deal with them. Then Trade Ideas uses those reads to draft offers the other side has a reason to accept, checked against both rosters first.

A few things worth knowing:
• It's read-only. A free account and your Sleeper username, never requires your Sleeper password, and it can't make moves in your league.
• Values come from Dynasty Dealer, built from real Sleeper trades, repriced for your league's scoring.
• There's a demo league you can open without an account: https://www.dynastyseer.com/demo
• Free covers one league. Pro ($9.99/month, 7-day trial) opens every league and every owner's report.
• Sleeper only for now, and not affiliated with Sleeper.

I'm a solo dev and I read everything. I'd love to hear what's confusing in the first five minutes, and which owner report was wrong about someone in your league.
