Get started

Upload your portfolio.

Bring your Underdog and DraftKings portfolio in with the free Milly Metrics extension. One upload powers Command Center all season.

One file, both platforms — every team you drafted and everyone in each of your pods
Chrome Extension
Underdog + DraftKings
One file, both platforms
Here’s all it takes
Six steps, about two minutes. Step 4 is a one-time sign-in with your email — that’s what keeps your portfolio on your phone and updating all season. Prefer not to? Step 6 is a file route that needs no account.
1
First, add the free extension
One click and it’s installed — no setup, nothing technical.
2
Sync Underdog
Sign in to Underdog and go to this exact page:
When it has loaded, click the Milly Metrics icon in your Chrome extensions  and press Sync Underdog. It finds every team you’ve drafted and everyone in each of your pods. Only play DraftKings? Skip this one.
3
Sync DraftKings
Sign in to DraftKings and go to this exact page:
When it has loaded, click the Milly Metrics icon again and press Sync DraftKings. Only play Underdog? Skip this one.
4
Sign in to Milly Metrics
In the extension, press Sign in with email. Enter your email and we send you a link — no password to make up or remember. One time only; the extension stays signed in after that.
5
Send to Milly
Press Send to Milly. Three named bars show exactly where it is — reading your teams, scoring your portfolio, building your Command Center. The last one is the slow part and takes about a minute; the Open Command Center button appears when it’s genuinely ready, not before.
Want it on your phone? Press Open on my phone for a code — scan it and Command Center opens there, already signed in.
6
Or upload the file
Prefer a file? In the extension, press Save the file instead, then drag milly_portfolio.json into the box below, or click to browse for it. On a phone, choosing the file starts the upload right away. No account needed for this route.
