Get the right call, fast — explained in plain English, not rulebook-speak.
For every parent, coach, and umpire who never memorized the rulebook.
What UmpGPT does
Two ways to ask. One right answer.
Most volunteer coaches know the game — but nobody memorizes the rulebook. UmpGPT lets you ask about a rule, or just describe what happened on the field and get the right call back.
Ask for the rule
Coach
"What’s the infield fly rule?"
UmpGPT
"With runners on first and second (or bases loaded) and fewer than two outs, an infield fly that can be caught with ordinary effort is automatically called out by the umpire — even if it drops. Runners may advance at their own risk but aren’t forced…"
Describe the play, get the call
Coach
"Runner on first and second, no outs, batter pops up to short center, the SS drifts back and lets it drop. Was that legal?"
UmpGPT
"No — that’s the infield fly rule. The umpire should have called the batter out automatically before the ball even landed. Runners stay where they are, no force play. That rule exists exactly to prevent the play you’re describing."
For the whole ballpark
Who is UmpGPT for?
Parents
Confused by a call? Get what happened, why, and whether it was even right — even if you only caught half of it.
Coaches
Is that sub legal? Was that call correct? Look it up, or talk the situation through before you take it to the ump.
Umpires too
