# Posture Reminder AI for Mac > Posture Reminder AI uses a Mac camera to detect slouching and provide posture reminders during desk work. ## Product - Native Mac app with separate sitting and standing calibration. - Posture monitoring runs on the device; camera images are not uploaded during monitoring. - Switch between built-in and compatible external cameras, or change reminder timing, without restarting the app. A new camera may require recalibration. - Energy Saver keeps monitoring in the background; reopen the window from the Dock or menu bar. - One-hour full-featured trial, followed by a Mac App Store subscription for continued monitoring. - Subscription verification requires an internet connection; monitoring can then work offline. - Intended for posture awareness, not diagnosis or treatment of a medical condition.
