Position coaching from your own video

Your position, corrected frame by frame.

Upload a short clip of your ride. Rosalind finds the moments your position slips and draws the correct position over your own video, so you can see the change instead of guessing at it.

One trot stride from a rider’s own video, as our coach sees it: the rider is a shape, never a picture.

How it works

All you need is a phone.

  1. 01

    Film

    Ask a friend to film you from the side of the arena. A few strides of trot or canter is enough, and a phone is all it takes.

  2. 02

    Upload

    Rosalind tracks your shoulders, hips, knees, heels and hands in every frame, then picks out the moments your position slips.

  3. 03

    Watch

    Your coaching video slows down at each fault and shows the correct position over yours, with what to change in plain words.

The correction

Drawn on you, not on a diagram.

Every correction keeps your own proportions. Your arms and legs stay their length, your hands stay on the reins, and only the joints that need to move do.

Rosalind only points out faults it is sure of. One fix you can trust is worth more than ten you have to second-guess.

Fault
Chair seat, tipping forward to balance
Upper-body lean
22° → 8°
Heel ahead of hip
0.33 → 0.00 torso
Fix
Lower leg under your hip, then sit tall

Privacy

No picture of you ever leaves our servers.

A shape, not a person

Before any frame reaches our AI coach, every person in it is replaced with a solid shape. It never sees your face, your body, or anyone else at the barn.

Your choice for your horse

Keep your horse as filmed, so the coach can read its legs and stride, or have it traced as a shape too.

Kept only as long as you say

You choose how long we keep your video: 24 hours, 7 days, 30 days, or until you delete it. While it’s stored, it’s locked so that only you can open it.

Our AI provider receives only these silhouette frames. Under its business terms it may not train on them, and it normally deletes them within 30 days.

Rosalind is in private testing.

We’re working with a small group of English riders before opening to everyone. Leave your email and we’ll write when there’s a place for you.

We’ll only use it to tell you when there’s a place for you, and we never share it.
