The product

Blue42 handles your starts, trades, and draft picks.

Stop bouncing between six ranking sites and four podcasts every Sunday. Blue42 answers your question, grounded in your actual league, not generic projections.

01 / Lineup Assistant

Every start/sit graded with confidence, and with a reason.

Risky calls flagged in gold. Ask why and get the matchup, snap trends, injury context, and how this player has historically performed in similar spots.

FAQ

Frequently asked.

Everything you might want to know before signing up.

What's actually in the box?
A web app and a Chrome extension. The web app is the full chat assistant + lineup view. The extension overlays your league’s draft room with live recommendations during your draft.
Which leagues do you support?
ESPN, Sleeper, and Yahoo at launch, with more platforms coming. We auto-detect your scoring, roster slots, and league size. No manual setup.
How is this different from the AI in my league app?
Your league app's AI matches last year's data to templates. Blue42 looks at this week: snap trends, Vegas lines, your opponent's actual roster. It tells you how confident it is in every call.
How much does it cost?
$29.99/season for full access: chat assistant, Chrome extension, every league you manage across every supported platform.
Is this gambling?
No. Blue42 is strictly for season-long fantasy football decisions: start/sit, waivers, trades, and drafts. We don't touch DFS, sportsbooks, or prop bets.
When do I get access?
We're rolling out access in waves. You'll hear from us directly when your spot opens.
