Aaron Judge
O 0.5 HR · NYY @ BAL
“Judge is 9-for-22 lifetime off Bradish with three homers, and has gone deep in three of his last four road games…”

What we built
The research stack other apps don't have.
ParlayPlug isn't a feed wrapped around scraped odds. We built our own models, our own signal feed, and our own citation chain — from the database up.
Proprietary
Per-at-bat MLB model
Every MLB prop graded at the at-bat level — pitcher arsenal, batter zone profile, park, weather. The level books price on.
Proprietary
Per-possession NBA model
Possessions, pace, defensive matchups, usage — built from scratch, and it shows in the lines we catch early.
Industry-first
Citations on every play
Every research brief links to the underlying data. If you can't check the source, it's a guess. We don't do guesses.
Real-time
Sharp signal feed
Steam, reverse line movement, and sharp-vs-public splits — pushed to your phone in seconds.
Why ParlayPlug
A research tool, not a pick service.
Most betting apps sell you a number. ParlayPlug gives you the research to make the call yourself — and the receipts to back it.
Tells you what to bet.
Shows you why the line is what it is.
Every prop opens to a source-cited brief — recent form, matchup, pace, injuries. No vibes, no screenshots.
Picks dropped after the move.
Sharp money the moment it lands.
Steam, reverse line movement, and sharp-vs-public splits — surfaced in seconds, not 30 minutes late.
One number per prop.
Per-at-bat and per-possession models.
Our MLB model grades at the at-bat level, our NBA model per possession — the granularity books price on.
From the founder
“I built ParlayPlug because the apps I was using were either pick services dressed up as tools, or scraped odds with no research behind them. There was nothing for people like me — bettors who wanted to do the work, but didn't have a Bloomberg terminal for sports.”
