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. MediaPipe and similar models learned to extract precise body landmarks from ordinary 2D video — something that used to require physical markers and stereo cameras. The accuracy now rivals lab-grade systems for most use cases.

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.
