About Dynasty Seer

A GM for your Sleeper dynasty league.

Dynasty Seer is a set of dynasty fantasy football tools for Sleeper leagues. It gives you trade values from real trades, a trade calculator, AI trade ideas, and scouting reports on every owner in your league.

It was built for Sleeper dynasty leagues, the kind where you trade with the same eleven people year after year and everyone remembers who fleeced whom. Redraft, keeper, best ball and guillotine leagues work too; the dynasty reads (picks, rebuilds) just switch off.

How it works

Your league, read the way you would read it

01

A free account and your Sleeper username

Make a free account, link your Sleeper username, and it finds your leagues through Sleeper’s public data. It never asks for your Sleeper password, there is nothing to install, and it never makes a move in your league for you. Dynasty Seer is not affiliated with Sleeper.

02

Values priced for your league

Player and pick values come from Dynasty Dealer, who build them from real Sleeper trades rather than votes. Dynasty Seer then reprices them for your league: a superflex QB or a TE-premium tight end is worth more there, and the numbers say so.

03

AI that works from your league

The AI runs on Claude, by Anthropic. It writes Trade Ideas (every deal is checked against both rosters in code before you see it), a dossier on each owner, trade verdicts, lineup and waiver advice and the weekly recap, and Ask the Seer answers questions about your league.
