Why SitSense Works

Real data. Real people. Real posture change.

How SitSense Works

SitSense uses your webcam to read seven clinical posture metrics in real time, entirely on your own machine. Instead of scoring you, it turns how you sit into weather: sit tall and the light is bright, and the axolotl you hatched can work. Her reef comes back one piece at a time on the light you make, she brings back a story from every night you sat, and once a week she asks how your neck and shoulders actually feel. No points, no streaks, no leaderboard. Nobody comes back daily to be graded.

Who SitSense Is For

SitSense helps anyone who spends long hours at a desk: remote workers, students, software engineers, designers, call center teams, and even gamers. If your day involves meetings, deep focus sessions, or long study blocks, SitSense keeps your posture consistent, reduces neck and shoulder tension, and builds healthier work habits automatically in the background.

Why Webcam Tracking Works

Webcam-based tracking works because it gives you feedback exactly when posture starts to drift. Our analysis of 540+ hours of real posture data shows most strain begins with subtle alignment changes—head–neck angle, forward head posture, and tilt. SitSense detects these moments early and guides you to reset before discomfort and fatigue build up.

Private. Local.

Finals week had me hunched over my laptop 11 hours a day, and my neck was killing me. SitSense gave me posture alerts and simple coaching exercises that relieved the pain.

SitSense is incredibly intuitive - it's the kind of tool people can pick up instantly. As a pediatrician, I see every day how much we need accessible solutions like this to prevent posture-related issues before they become long-term.

Yes — posture tracking is free to use, with no trial and no credit card. Pro plans add long-term trends, full session history, and a lifetime AI coach.

SitSense processes all video analysis locally on your device—no video or images are ever stored or transmitted. Only numerical posture metrics are saved to help track your progress over time. The interface is minimal and can be hidden, and all video processing happens in your browser without external network calls.

SitSense works on any device with a webcam and modern browser. We support Chrome, Firefox, Safari, and Edge on Windows, macOS, and Linux. The app works entirely in your browser—no downloads or installations required.

Unlike wearables like Upright GO or the discontinued Lumo Lift, SitSense uses your webcam to analyze full upper-body posture—no device to wear, charge, or clip on. Webcam-based tracking detects forward head posture and slouching more accurately than single-point sensors. See our Lumo Lift alternatives guide for a full comparison.
