The first project worth a look is Posture Reminder. This AI-powered app uses computer vision and AI to monitor your posture and warn you immediately. It's built for Mac hardware and stores data locally to protect privacy. It works offline, so you can use it anywhere, and you can set the frequency of warnings and the camera you use.
The second good option is BliiNK. BliiNK is a desktop app that uses AI to nudge you toward good working habits. It checks your posture from time to time, warns you to blink to avoid eye fatigue and suggests exercises to ease neck and back pain. It runs on your machine, so your data is private and secure, and it offers historical reports and customizable reminders for a more complete approach to improving your working style.
