From research lab to webcam: democratising biomechanics

A decade ago, getting a biomechanical breakdown of your batting technique meant booking time at a sports science lab. Reflective markers, multi-camera setups, post-processing — all to tell you your front knee bend was 5 degrees off.

Today, the same analysis runs in your browser using a $30 webcam. The technology that powered Olympic athletes is now in the hands of any club cricketer or yoga student.

The key shift was deep learning on pose, not pixels. YOLO-Pose and similar models extract precise body landmarks from ordinary 2D video — something that used to require physical markers and stereo cameras. Training on pose sequences makes shot recognition sample-efficient and robust to camera angle.

What this unlocks is staggering. A 14-year-old in a small town can get the same coaching feedback as a national-level player. A yoga student can correct her form without paying for a private instructor. The cost of expert biomechanical advice has effectively dropped to zero.

We're at the start of a coaching revolution. Over the next five years, AI coaching will expand into tennis, golf, swimming, weightlifting — anywhere movement matters. Gaara AI is just one player in this future. We're excited to build it.
