// ask it anything

It already did
the homework.

Every answer starts from your real rosters, your league's real scoring, and what's actually happening around your league — in any sport you play.

// how it works

Link. Ask. Win.

From zero to answers in about two minutes — no spreadsheets, no manual entry, no passwords.

1

Link your leagues

Every league you own, in one place — all seven platforms, all six sports. Connect with a username or league ID. We never ask for your passwords.

2

Ask anything

A trade you're weighing. Tonight's lineup. Who to grab off waivers. What to do at pick 2.07 with the clock running. One AI, every question.

3

Win with real context

Answers are built on your roster, your opponent's roster, and your league's actual scoring settings — not a generic cheat sheet somebody else made.

// the toolkit

Built for every week
of your season.

Draft day, trade deadline, waiver Wednesdays, and every lineup lock in between.

Live Draft Mode FREE

Pick-by-pick board tracking, "you're on the clock" push alerts, and ranked pick suggestions the moment your turn gets close. Draft-day AI is always free.

Two-Sided Trade Grades

Grade any deal — players and picks — against both teams' actual rosters. "Their Angle" shows what your trade partner is really thinking, so you know if it'll land.

Player Analysis

Any player, any sport: value, injury history, role, and a straight keep / trade / drop call — in the context of your roster.

Injury Intel

Injury designations synced twice a day across all six sports, wired straight into every start/sit call and trade grade.

Waiver Targets

Adds ranked by what your roster is actually missing — bye-week holes, injury cover, and league-mates' drops you shouldn't sleep on.

Set-and-Forget Sync

Rosters refresh automatically, and dynasty leagues follow you season to season — when your platform mints a new league ID, we find it and carry your team over.

// coverage

Every league.
One locker.

Most tools stop at one sport on one platform. We went 6 and 7 — this is the actual grid.

// questions

Fair questions.

The honest answers, no fine print.

Do I have to give you my league passwords?
Never. We connect through each platform's public or sanctioned API — a Sleeper username, a league ID, an FPL team number. We never ask for, store, or use platform passwords. For Yahoo, sign-in happens on Yahoo's own site via OAuth.
Which sports and platforms are covered?
Six sports — NFL, NBA, MLB, NHL, WNBA and Premier League soccer — across Sleeper, ESPN, Yahoo, MyFantasyLeague, Fleaflicker, Fantrax and FPL. Dynasty, redraft and best ball formats all work. Yahoo Fantasy covers NFL, NBA, MLB and NHL and is available in the United States and Canada.
Is draft help really free?
Yes. Whenever one of your drafts is upcoming or live, AI pick advice is unmetered — live board tracking, on-the-clock alerts, ranked targets, all of it. Draft day is when you need help most; we're not charging you per pick.
How is this different from a trade calculator?
Calculators compare crowd-sourced values in a vacuum. Roster Locker grades the deal against both teams' actual rosters, your league's actual scoring, and your timeline — then shows you the trade from your partner's side so you know whether they'd even accept.
What does "founder pricing locked for life" mean?
The price you lock in today is the price you keep — permanently — no matter how much the product grows or what new members pay later. Upgrade now and that rate is yours for good.
Is it live? How do I start?
It's live right now, and it's free to start — no credit card. Create an account, connect a league, and start asking. Upgrade only when you want more sports or more AI actions, and your founder price locks the moment you do.
