A GM for your fantasy team

Same tier, so it’s a small edge rather than a clear one. Want me to check your bench for anyone who fits better?

01 · What it does

Five jobs. One conversation.

No tabs, no tools to learn. Ask, and it answers about your team, then takes the follow-up.

01

Drafts with you

Reads your board, your roster and the chance a player lasts to your next pick.

02

Prices trades

What each side gives up, and how much your starting lineup changes.

03

Finds pickups

Who on your waiver wire fills a hole on your roster, and by how much.

04

Sets lineups

A start and bench call for the week, slot by slot.

05

Counts bench points

The points your bench left behind, week by week.

02 · How it connects

Three steps, once

Add it to Claude, sign in, allow access. After that it’s there in every conversation.

03 · The rule it follows

Fit, never foresight

It tells you what fits your roster and by how much. It doesn’t predict scores and it doesn’t promise results. Nobody can, so it won’t pretend to.

Every call gets made

You get an answer, not a shrug.

With its margin

Close calls are called close.

Fit to your league's format and roster.
