A macOS menu bar app that keeps your Mac awake by detecting your presence with the FaceTime camera. Local & private — No networking, telemetry, third-party dependencies, or even temp-directory writes; captured frames are processed in memory and discarded immediately. Hardware-accelerated — Uses Vision on Apple Silicon; face detection runs on GPU or Apple Neural Engine, not CPU. Smart presence detection — Skips camera checks when you've used the keyboard or mouse in the last 30 seconds.
