How the toolsactually work.
PostureUp offers two free instruments: a Live Posture Check that reads your alignment through your webcam, and a Workspace Audit that reviews a photo of your desk. This page documents what each one measures, where the numbers come from, and what happens to your data.
Two instruments, one goal
Both tools hunt the same habits that quietly work against your neck, back, wrists, and eyes, each from its own vantage point.
A ~60-second reading of you. An on-device pose model tracks 33 body landmarks through your webcam, front view and then side profile, and scores your alignment against the posture signals below.

The seven workspace anchors
Every audit report is built around the same seven anchors, each drawn from established workstation guidelines published by OSHA, CCOHS, and HFES.
The posture signals
The Live Posture Check reads a different set of signals: yours. A pose-estimation model locates 33 landmarks on your body every frame and measures the geometry between them: is the shoulder line level, is the ear stacked over the shoulder, is the trunk stacked over the hips. Each signal is scored against thresholds from physical-therapy literature, like the craniovertebral angle used to screen for forward head posture.
Signals are smoothed over ~30 frames before anything is flagged, so a stretch or a glance at your phone doesn't skew the reading. Each flag comes with plain-language advice on how to correct it, free, every time you check.
Your data
The two tools handle data differently. Here's exactly how.
Live Posture Check
The pose model runs entirely in your browser. Your camera feed is processed frame by frame on your own device. No video, image, or landmark data is uploaded, stored, or sent to any server. Close the tab and every frame is gone.
Workspace Audit
Your photo is uploaded once, analyzed, and deleted after analysis. We ask for an email address to deliver the full report; it's the only personal information the audit collects, and the privacy policy covers exactly how it's used.
Who it's for
Remote workers
A second opinion on a home setup that nobody else is going to come look at.
Office employees
A sanity check on a corporate workstation you can’t fully replace.
HR & wellness teams
A self-serve option to offer employees as part of a wellness program.
Anyone with nagging discomfort
A starting point if you suspect your desk, or your habits, are part of the problem.

What it isn't
Both tools are screening tools. They catch the obvious stuff and give you a starting point. They are not medical advice and don't diagnose anything.
If you have chronic pain, an existing injury, or a workspace that needs custom equipment, see a certified ergonomist, a physical therapist, or an occupational health specialist. Please talk to a qualified professional before changing your exercise, treatment, or equipment based on what the tools report.
Common questions
What tools does PostureUp offer?
Two free tools. The Live Posture Check reads your posture in real time through your webcam, entirely in your browser. The Workspace Audit reviews one photo of your desk setup with AI and writes back a prioritized report.
Is my camera footage uploaded during the Live Posture Check?
No. The pose-detection model runs on your device, inside your browser. No video or camera frames are uploaded, stored, or sent to a server. When you close the tab, every frame is gone.
What happens to my Workspace Audit photo?
The photo is analyzed and then deleted. We ask for an email address to deliver your full report; that is the only personal information the audit collects.
Are the tools free?
Yes. Both tools are completely free, with no paywall. We believe everyone should be able to get feedback on their posture, with free advice on how to correct it, throughout their working life.
Are the results medical advice?
No. Our methodology is reviewed by Dr. Mir Shithil, a licensed Doctor of Physical Therapy in New Jersey with his degree from New York University, and the tools still remain general-awareness screenings. They don't diagnose conditions and don't replace a licensed physical therapist, chiropractor, occupational health specialist, or physician.
Rolling this out across a team?
There's a separate enterprise track for bulk assessments, aggregated reporting, and integration with existing wellness programs.
