Sit better, feel better — without thinking about it. PostureGuard uses your webcam and on-device AI to spot slouching in real time and gently nudge you back upright. Private, free, and ready in one click.
Free · No account needed · Works on Chrome, Edge & Firefox
PostureGuard watches — privately, on your own device — and tells you the second you start to slouch, so sitting well becomes a habit instead of a chore.
Catches the slouch as it happens — not hours later when your back already aches. The faster the nudge, the easier it is to correct.
Your camera feed is processed entirely on your device. Nothing recorded, nothing uploaded, no account required. Ever.
Soft sound and voice cues, with smoothing built in so it won't false-alarm every time you reach for your coffee.
Status is color-coded — green when you're good, red when it's time to adjust — so a glance is enough.
You get audio alerts in a tone of your choice, plus a friendly spoken reminder if you've been slouching for a while.
Habit reminders and session history let you watch your posture improve over time. No graphs to interpret. Just a record of better days.
Video is analysed on your device and is never stored or uploaded. There is no account, no server, no recording. Close the tab or quit the app, and it's gone.
Instant. Nothing to install. Just open the tab and let PostureGuard see you — best when you want to try it or use it for a single session.
Launch PostureGuard For everyday useInstall once and let PostureGuard run quietly in the background while you work. Always on, ready when you sit down.
