On-the-clock mode
When you're up, the board flips to the question that matters: if I pass, does he make it back to me?
How it works
- Install the extension and sign in to LeagueSeer in the same browser. Accounts are free.
- Open any Sleeper or ESPN draft room, the panel appears top-right and claims your seat automatically.
- League drafts need the league added to your account; Sleeper mock drafts work with just a sign-in.
Privacy: the extension reads only the draft room's URL, never page content, and talks exclusively to leagueseer.com. Details in our privacy policy.
Drafting on your phone? The web app installs to your home screen with the same live HUD and push alerts when you're on the clock.
