See the trade before your league does.
Dynasty fantasy football tools for Sleeper leagues that scout your league-mates, not just the players: how each owner trades, drafts and sets a lineup, beside values from real trades. You still make the call. You just make it first.
Your whole league, priced from real trades
Every roster and draft pick is valued with Dynasty Dealer data from hundreds of thousands of real Sleeper trades. A report card grades your team and lists the first things to fix.
Startup draft coming up? Practice here, then draft with the Seer
Run a full mock startup against computer teams that draft for their lineups, free and with no account. When the real one starts on Sleeper, paste its link and the Draft Assistant follows it live.

- Then follow your real Sleeper draft live, every pick on the board
- Best available priced for your scoring and lineup, in tiers
- Picks until your turn, third-round reversal and traded picks counted

Six tools that give you the edge
Deals that make you better, pitch included
Your AI GM reads every roster, your league’s settings and how each owner trades. Then it drafts the offers the other owner has a reason to accept, ranked by what they do for you, each with a message you can paste into Sleeper.

Know every owner before you make an offer
Years of trades, drafts, waiver claims and matchups become a profile of every owner in your league: who hoards running backs, who buys picks, who wins their trades and who only deals in the offseason. Trade Ideas uses the same profiles to pitch each owner a deal they’ll actually take.

Questions
Is Dynasty Seer free?
Yes, to start: the Free plan covers one league, with 2 AI analyses a month. Pro ($9.99 a month or $79 a year, with a 7-day free trial of 15 AI analyses and 5 Trade Ideas runs) covers every league, Trade Ideas and much more AI.
Do I need an account or my Sleeper password?
You make a free Dynasty Seer account and link your Sleeper username to it. Never your Sleeper password: the app only reads public league data.
Can Dynasty Seer set my lineup or send trades?
No. Sleeper has no public way for other apps to change lineups or send offers. Make the moves in the Sleeper app.
Which leagues work?
Sleeper dynasty, keeper, redraft and guillotine leagues, 1QB or superflex, with any scoring. Dynasty leagues use dynasty values; keeper, redraft and guillotine leagues use this season’s redraft values for their format, and the dynasty-only pages (Draft Picks, Market Movers, Prospects) stay out of their menus. Other platforms (ESPN, MFL, Yahoo) are not supported yet.
Does Dynasty Seer help with a startup draft?
Yes: the Startup Mock Draft lets you practice one in your format (teams, 1QB or superflex, TE premium, PPR, rounds), free and with no account. When your league’s real startup runs on Sleeper, the Draft Assistant follows it live with the best available by your league’s values, the picks until your turn and the starting spots you still need.
Why don’t values match KeepTradeCut or FantasyCalc?
Values come from Dynasty Dealer, built from real Sleeper trades rather than votes or rankings, so they will differ.
