Dynasty Seer
Compare dynasty tools

Most tools price the players. Dynasty Seer reads the owners.

Most dynasty tools stop at values and a calculator. Dynasty Seer also scouts every owner you trade with, from your own league’s history, and then writes the offer. If you play in a Sleeper dynasty league and want to win the trades in it, that is the difference.

What sets it apart

Built around the people you trade with

Owner scouting is the whole point.

For every owner in your league you get who sends offers and who waits for them, how fast they accept, what they overpay for, who they have never traded with and when they tend to sell, along with how much history each read rests on.

The AI turns that scouting into a trade you can send.

Trade Ideas and the owner dossier hand you a priced deal that has already been checked against both lineups and each team’s window, plus a first message to the owner.

You know where the values come from.

They are Dynasty Dealer’s, built from real Sleeper trades, and repriced for your league’s scoring, lineup slots and number of teams.

Choices we made on purpose

Built for Sleeper

Dynasty Seer works with Sleeper leagues only. That is what lets it read every league setting on its own, scoring, superflex, TE premium, roster size, taxi and IR, co-owners, past seasons, without you filling in a form.

It never touches your league

Never your Sleeper password, no moves made on your behalf. Dynasty Seer tells you what to do and why, and you send the trade or set the lineup in Sleeper yourself.

No rankings columns

There are no hot takes here. Everything comes out of your league’s own trades and seasons, and each read says how much history is behind it.
