Everything you need to sit better
Live silhouette
A colour-coded outline of your body. Green when good, amber when fair, red when poor. Your face is never shown.
Six body metrics
Neck angle, head forward, craniovertebral angle, shoulder slope, head tilt, and slouch — updated every frame.
Named, not graded
See which of the six tracked angles is drifting, live, while you work. The extension names the joint rather than scoring you.
Sound alerts
Gentle audio nudges when your posture has been poor. Toggle on or off anytime.
Coaching tips
Actionable advice like “tuck your chin” or “level your shoulders”, based on what is actually off.
100% private
All AI processing happens locally in your browser. No video or data is ever sent to any server.
