Our Story
Golf tech got really good at numbers.
It forgot about coaching.
We logged thousands of range balls on a launch monitor, tracked every round, watched spin rates and attack angles fill up dashboards we didn’t know how to read. The numbers kept piling up. Our handicaps didn’t move.
What was missing wasn’t more data. It was someone to look at the data and say “here’s what’s actually going on, and here’s what to work on next.”
That’s the job a great club pro does in thirty seconds. OpenCaddie puts that pro in your pocket.
That pro is real, too. We work with TPI certified coaches with over twenty years of teaching experience to build our drills and shape the knowledge base and context engine Mully coaches from.
The AI swing apps are decent, but you’re measured against a pro’s mold and chasing an impossible goal. The general AI tools work only if you know how to feed them the right context. OpenCaddie is for the rest of us. It finds the weak spots and lays out a practice plan with the structure to actually follow it.
I’ve been using OpenCaddie for about two months now and I’ve been extremely impressed. It’s a one-stop shop for me to keep track of my scoring data, range data, club gapping, practice schedule and progress against key metrics. New features keep coming out, but frankly I’m not sure what else someone could need.
Your session, replayed
We read the numbers.
Then we fly them.
StrikeView rebuilds each shot from your launch monitor export: carry, launch, spin axis, offline. Then it replays the session in first person. Press play and watch three real flights.
Then post the good one.
One tap turns the session into a story-sized card: your best strike, why it won, where every other ball finished, and one line from your coach. Vertical, ready for the group chat.
Meet Mully
The coach inside OpenCaddie.
We built Mully so you'd get coaching, not another dashboard. It reads the shots you already capture, finds the one thing costing you the most strokes right now, and hands you a real drill to fix it.
- 1
Reads what you've got
Your launch monitor exports (TrackMan, SkyTrak, Foresight, GSPro, Garmin, Arccos), your rounds, and your bag with its target carries.
- 2
Finds the leak, names the cause
It checks your delivery numbers against the ball-flight laws and your stats against benchmarks for your handicap. A fat 7-iron is a low-point problem, not a distance problem.
- 3
Prescribes a drill by name
A named drill from a 60-drill catalog coaches actually use, tuned to your numbers. Towel-behind-the-ball, 7-iron, 165-yard target, three sets of ten.
- 4
Adapts to how it felt
Tell Mully it clicked, you struggled, or you want to repeat it, and the next day's Practice Station adjusts. The more you play, the sharper it gets.
- 5
Checks its own work
Every drill it prescribes gets tracked against your next sessions and marked cleared, improved, or didn't work, judged on the same benchmarks it coaches from. Your next review opens by settling the last one.
Mully's instruction is grounded only in established authorities: TrackMan ball-flight data, Mark Broadie's strokes-gained research, and shot databases from Arccos and Shot Scope. PGA-level and evidence-based. See where Mully's advice comes from →

What a Practice Station looks like
Not a screenshot.
The actual Practice Station.
This is the same component that runs inside SwingLab, loaded with a sample player’s data. Tick a drill, open one and read the execution steps. It behaves here exactly as it will for you, because it is the same thing.
The Drill Catalog
A drill for every miss.
Mully pulls from a 60-drill catalog coaches actually use, matched to what your numbers say you need. A slice of it:

MULLY READS ALL OF IT
Towel-behind-the-ball · 7-iron · 3 × 10
Your low point drifted behind the ball across three sessions on two different monitors, and it showed up again in Sunday’s round. This puts it back in front.
Own more than one? Switch between them whenever you like. Every session still lands in the same picture, and the practice you get back is built from all of it.
Your data stays yours. Every shot, round, and Practice Station lives in your account with row-level security. We don’t share it, aggregate it across users, or use it to train models.
