Scorecard Scanner
Photograph the card. That is the entry.
Claude Vision reads paper scorecards — handwritten, printed, or tournament-issued. Course name, hole pars, your scores, and your putts, extracted in seconds. No retyping.
How it works
Three steps. About 10 seconds.
Open the scanner
In the round-entry flow, tap "Scan card." The phone camera opens with a frame guide for the card.
Photograph the card
Hold it steady. Make sure all 18 holes are visible. Tap the shutter. The image uploads in under a second on a decent connection.
Review and save
Claude Vision returns the extracted course, pars, scores, and putts. Tap any cell to correct it. Save.
What it handles
Every scorecard format
Handwritten
Pen, pencil, anything legible. Some clubs still issue blank cards.
Printed
Most modern resort and championship scorecards. Highest accuracy.
Tournament
Attested cards from medal play, with both gross and net columns.
9-hole
Front-nine-only cards from quick rounds or 9-hole loops.
Why this exists
The clubhouse-to-app problem
Most amateur rounds still get written on paper. You finish 18, sit down at the clubhouse with a beer, sign the card, and pocket it. By Tuesday, the card is gone or in a drawer. The round is never logged.
Manually typing 18 holes of scores and putts into an app takes about 4 minutes — long enough that most golfers will not do it. The Scorecard Scanner closes that gap. Photograph the card on the way to the car. The round is in your history before you reach the parking lot.
It is the single feature most reliably mentioned by tournament golfers and society players — anyone whose rounds happen across multiple courses and formats.
FAQ
About the Scorecard Scanner
Can it read handwritten scorecards?
Yes — Claude Vision is the model that runs the scanner. It reads clear handwriting as well as printed cards. Messy handwriting reduces accuracy; you can review and edit the extracted scores before saving.
What does it extract?
Course name, hole pars, your scores per hole, and putts per hole (if you marked them). For 9-hole and 18-hole cards alike. It does not extract other players' scores from the same card.
How accurate is it?
Around 95% on clean, printed scorecards. Around 85-90% on handwritten cards. We always show you the extracted round for review before saving — you can correct any miss-reads in seconds.
Does it work on any course?
Yes. The scanner does not need to match the course to our database. If your course is not yet in our 17K+ index, the round still saves and we add the course to the database afterward.
Is the photo stored?
No. The image is sent to Claude Vision over a secure API and discarded after extraction. We only store the extracted text — scores, putts, course name. See our security page for details.
Which AI model does it use?
Anthropic Claude Sonnet (vision-capable). The same model family that powers the AI coaching story uses a separate vision-tuned variant for OCR.
