DeskRange AI: Local-first AI posture coach for desk workers

Hey Product Hunt 👋 I built DeskRange AI because long desk hours were quietly affecting my posture, and most solutions I found were either generic reminder timers, wearables, or apps that didn’t adapt to how I actually sit. DeskRange AI is a local-first Windows posture coach. During setup, you calibrate it with your own good, medium, and bad posture samples. After that, it watches for posture drift during real work sessions and gives calm on-device cues when your posture starts slipping. The goal is not to force everyone into one "perfect" posture. It is to learn your personal posture range and help you stay aware while coding, working, studying, or sitting at a desk for long hours. It is built for developers, remote workers, students, and anyone who spends most of the day in front of a screen. Would love feedback on the positioning, onboarding, and whether this feels useful compared to normal break reminder apps.
