August 7, 2026 — NFL preseason Week 1.
Built for fans who already say “EPA” out loud.
What we're claiming
- 01
First tactical AI built for live sports.
Not a chatbot. Not a stats wrapper. The first product where a model that has actually read the coaches’ clinics talks to you on the snap — naming disguised quarters, robber, simulated pressure as the play happens.
- 02
EPA with the why attached.
The number floating through Twitter, finally with the reason next to it. Grounded in nflfastR play-by-play and Big Data Bowl tracking — when the model says fourth-and-2 was the right call, you get the win-probability delta and the historical comparison set, not a vibe.
- 03
An analyst’s brain. A friend’s voice.
The model says “suggests” when the data suggests, and “shows” when the data shows. No analytical-buyer-trust-burn from over-claiming. Voice discipline is the product.
The pitch & the play-clock
Three words this product speaks fluently. If you already do too, you're the audience.
- coverageWhat the defense is doing pre-snap and on the snap
Cover-2, Cover-3 buzz, quarters with a robber, simulated pressure that drops out — gamedai names it on the snap, the same way the QB has to read it.
- EPAExpected Points Added — the number Twitter quotes without the why
Every play has a value. EPA tells you whether the call was worth it; the confidence interval tells you how loud the data is. gamedai talks both, in plain prose, on the next snap.
- schemeWhat the playbook is — the pattern beneath the play call
Erhardt-Perkins. West Coast lineage. Shanahan wide-zone. The vocabulary coaches share with each other. gamedai uses the same words your favorite breakdown podcast uses, on the snap rather than on Tuesday.
How it works
Three steps. The third one is the snap.
Step 2 of 300:13Audio match · scheme loaded
Point at the TV.
The phone hears the broadcast. Game recognized in under three seconds — kickoff time, score, down-and-distance, the team in possession.
Step 3 of 300:00Snap · interactive radio live
Hear the breakdown.
Snap. AirPods speak: coverage shell, EPA reasoning, the call against the call. Hedged when the data hedges. Quiet between snaps.
What you'll hear
The voice is hedged where the data hedges.
Live · Q3 · third quarter
- Q3 · 9:42 · gamedai
Cover-3 buzz on the snap. Robber rotated late from the boundary safety. The slot fade is the answer; QB went underneath. EPA on the play, plus 0.18.
- Q3 · 9:38 · you
why didn't they take the shot?
- Q3 · 9:38 · gamedai
The coverage suggests the safety help was over the top — typical Reid third-down look. Going underneath here is the higher-EPA play in 71 percent of comparable down-distances. Confidence interval is tight on this one.
- Q3 · 8:55 · gamedai
Fourth and 2 from the 38. EPA suggests going for it, plus 0.31 over a punt. CI is wide — red-zone fourth-downs are a small sample. Coaches who go on this exact down-distance-yardline convert at 56 percent.
Sample utterance. The product talks like an analyst who knows the confidence interval is part of the answer.
Built different
A hundred years of someone smart in your ear.
Sports radio has been the voice in the room since the 1920s. The TV broadcast skips the interesting reads. The postgame podcast comes Monday. gamedai is what radio becomes when the voice can answer.
- 1921
KDKA on the air
First commercially licensed radio broadcast carries a live game. The voice in the room is born.
- 1939
NFL on radio
Dodgers vs. Eagles, October 22 — the league’s first network broadcast. The analyst becomes part of the experience.
- 1987
Sunday Ticket arrives
Every game, every Sunday, on demand. The watch widens. The voice stays one-way.
- 2026
gamedai
The voice talks back. Ask why. Hear the coverage, the EPA, the call. The successor format, not a wrapper on the old one.
Proof
Built on nflfastR + Big Data Bowl 2026
Open NFL play-by-play with EPA, win probability, and air yards; Kaggle-released player tracking; the public datasets the analytical community has been working with for a decade. We didn't invent the math. We made it talk back.
Hedged where the data hedges
How the product talks. One sample utterance from a fourth-and-2 decision in the red zone:
EPA suggests going for it here was correct, +0.31 over a punt. Confidence interval is wide on red-zone fourth downs — historical N is small. Coaches who go on this exact down-distance-yardline convert at 56 percent. Yours just did.
From someone who runs his own EPA sheet
“I built this for the version of me who keeps the matchup sheet open on Sunday and yells at the TV when the announcers miss the disguised pressure. If that's you, you'll know on the first snap.”
