Mind how you sit.
A desktop coach that watches your posture from your own webcam, never the cloud. Local-first, calibrated to you, quiet by default.

Click start. We'll load the official MediaPipe pose model into your browser, ask for camera access, and grade your sitting posture in real time. Nothing is uploaded, every frame is processed on this tab.
The webcam stream and the model both stay on your device. We don't ship a single frame anywhere.
Calibrated to you.
One number, derived from your own two baselines. Watch what happens when you slip:
Streaks, day timelines, week views, a month calendar and a year heatmap, all stored locally. You can wipe the history at any moment without asking permission from a server.
Quiet when you ask.
A posture coach that keeps prodding during a presentation isn't a coach, it's a distraction.

Define rules for calls, screen-shares and specific apps. Posture Maxing detects them and goes quiet automatically. Windows ships the full app-detection pipeline today; macOS and Linux start with the call and manual rules.
Webcam frames never leave your device.
Posture Maxing was built local-first. The MediaPipe pose pipeline runs in the renderer process and never sees a network.
There is no account to sign up for, no telemetry to opt out of, no cloud to send your posture data to. The browser demo on this page loads the MediaPipe runtime from a public CDN, your webcam frames still never leave the device. See the privacy policy for details.
