Fix your posture without uploading your face to someone's cloud.

UpSit watches how you sit through your webcam and nudges you the moment you slouch — with every frame processed on your device and nothing, ever, sent anywhere.

Windows · macOS · Linux

Private by architecture, not by promise. Pose detection runs in a bundled on-device model. The app makes exactly one network request in its lifetime — validating your license key — and none after. No account. No telemetry. Your camera feed physically cannot leave your machine.

Built to run all day and stay out of your way

Real-time posture score

Slouching, forward head, uneven shoulders, leaning — detected geometrically and scored 0–100, live.

Gentle reminders

A desktop notification only when poor posture is sustained — with a cooldown, so it nudges instead of nags.

Light on your machine

Low-resolution capture, a lite pose model, and an adaptive scheduler that slows inference down when your posture is stable.

Your trends, locally

Daily scores, streaks, and 30-day trends — stored in a SQLite file on your disk that you can inspect or delete anytime.
