Show HN: EyesOff – On-device AI that catches shoulder surfers (opens in new tab)

I built EyesOff after getting fed up with people glancing at my screen in coffee shops.

I trained a, custom and small, neural network to detect when people look at your screen. Whenever more faces than your allowed threshold are looking at your screen an alert will show. The model being ran locally ensures all data stays on your device - no cloud processing.

I would love feedback on the application and any features you think I should implement!
