A New Way To Read

Every green read,
in seconds

Reading a putt well is a skill that takes most golfers years to build. You have to judge the slope, factor in how fast the greens are running, decide how hard you want to hit it — and then turn all of that into a precise aim point. Get any one of those wrong and the ball never had a chance.

The AI Caddie does that maths for you. It asks you what a real caddie would ask — how much slope, how quick the greens, what pace — and gives you an exact line, down to the inch. It reads like a tour pro, but it fits in your pocket.

And it's not a separate app to download. It's built straight into the Line Speed Read tools you already use — the drills and the strokes gained calculator — so a read is never more than a tap away.

The Idea
"Give me a read on this one."
"Sure. What % slope do you see here?"

How It Works

Talk it through,
one question at a time

Tap "Give me a read" and the caddie takes over — one focused question at a time, exactly the way you'd think it through standing over the ball.

1

What distance is this putt?

Pick from the common distances or tap Dist to enter your own, anywhere from 2 to 40 feet. Inside the practice drills the caddie already knows the distance, so it skips straight to the slope.

2

What % of slope are you seeing?

Read the % slope of the green and tell the caddie — gentle, medium or strong. It's the single biggest factor in how much a putt breaks.

3

What is the stimp on the greens?

Faster putts break more, so the caddie scales the read to the surface you're putting on.

4

What entry speed are you thinking?

Dying it at the hole, or rolling it a foot or two past? Entry speed changes the break — and the caddie accounts for it before it gives you a number.

Read The Read

From the edge, or
from the centre

Here's where the AI Caddie teaches you something most golfers never learn properly: there are two honest ways to describe a break, and knowing the difference makes you a better reader.

The break from the centre of the cup is the pure physics — how far the ball curves relative to the middle of the hole. It's the number that follows the rules cleanly: double the slope and you roughly double the centre break.

But that's not what you aim at. What you actually pick out is a spot outside the edge of the hole. And because the hole is a fixed 4.25 inches wide, the edge reference behaves differently — a putt that breaks a little from centre might only need a sliver outside the edge, while a big breaker needs a read well outside it.

The caddie shows you both, with a single tap. Learn to see a putt in both frames and you'll start reading greens with your own eyes far more accurately.

The Other Half Of Every Putt

It reads the line
and the speed

A perfect read is only half the putt. You can pick the ideal line and still leave it short or blow it four feet by, because pace is what actually holds the line you chose. Most amateurs lose far more putts to poor speed than to poor reads.

So the AI Caddie does both. The moment it hands you the line, it asks one more thing — "Need a tip for stroke length?" — and if you say yes it tells you exactly how far to take the putter back to roll the ball the distance you want, at the pace you want.

It already knows your distance, your green speed and your entry speed from the read, so there's nothing more to answer. You get a repeatable back-and-through length in inches or centimetres, so you can commit to one tempo and let the stroke do the work — the two things every holed putt needs, from one conversation.

The same engine that powers our
Putt Break Calculator
Built On Real Physics

Not a guess.
A calculation

The AI Caddie isn't pulling numbers out of thin air. It runs on the exact same break model as our Putt Break Calculator — the one built to read a putt as accurately as a tour-level green-reading system.

Slope, stimp and entry speed all feed into a single calculation, tuned against real roll data. That means the read you get from the caddie in the middle of a drill is identical to the one you'd get from the full calculator. One brain, everywhere you need it.

Common Questions

AI Caddie FAQ

How do I access the AI Caddie?

It's built into the Line Speed Read practice tools — open any of them in your browser and, once you've set your distance, tap the AI Caddie button to start a read.

How accurate is the read?

It runs on the same break model as our Putt Break Calculator, tuned against real roll data. It reads slope, stimp and entry speed to give an aim point accurate to a fraction of an inch.

What does "from the edge" versus "from the centre" mean?

They're two ways of describing the same break. "From centre" is the pure curve relative to the middle of the cup; "from the edge" is what you actually aim at, measured from the near lip of the hole. The caddie shows both so you can pick whichever helps you commit.

Can I use it during a competitive round?

The AI Caddie is designed for practice and casual play. Using a device for green-reading assistance is generally not permitted in competition, so keep it for the range, the practice green and social rounds — where it'll sharpen your own reading eye fast.

Do I need to know the exact stimp of my greens?

No — a close estimate is fine. Slow, medium and slick cover most greens you'll play, and the caddie scales the read accordingly. As you play more, you'll get a feel for your home greens' pace.
