How it works — SIGHTER

Record

A short video from side-on. Nets, match, or practice at home — anywhere you play. Your whole body should remain in frame.

A written review returns to you within one working day: what your technique is doing well, what merits attention, a drill to address it, and an honest account of what your camera angle could and could not show.

What this is

A considered examination of your technique, drawn from video. Computer vision reads your body position frame by frame, and a coaching framework built from the cricket biomechanics literature interprets what it finds. There is no generative AI involved and no language model — the same video produces the same review, every time.

What this is not

This is not medical advice, nor an injury assessment, nor a replacement for a coach who can watch you in person. Nor does it claim to measure precise angles: a single camera cannot capture rotation that occurs away from its viewing plane. This is a matter of geometry, not of software. Where your footage cannot support a conclusion, we say so rather than estimate.

How to record

Good footage is what separates a useful review from one obliged to say "this cannot be read." The essentials:

Film from side-on — the camera square to the crease, perpendicular to the pitch. This angle reveals the most.
Keep the camera level with the crease — not looking down from a balcony, nor up from ground level.
Keep the whole body in frame — head to feet, throughout the entire action.
Eight deliveries — that is what we review. One good over is ample; a full session is unnecessary.

Complete filming instructions are provided when you begin your first review.
