What is Drowsiness Alarm?

Drowsiness Alarm uses your computer's webcam to analyze eye closure in real time and sounds an alert when your eyes remain closed beyond the configured threshold. No app installation needed — it runs entirely in your browser, and your camera footage is never transmitted or stored. Ideal for long PC work sessions, late-night studying, or preventing drowsy driving.

Real-Time Eye Detection

Google MediaPipe AI and the EAR (Eye Aspect Ratio) algorithm analyze eye state more than 20 times per second, distinguishing natural blinks (under 0.2s) from actual drowsiness.

Customizable Alerts

Set the alarm threshold anywhere from 1 to 15 seconds. Choose from 4 alarm sounds — Beep, Alarm, Buzzer, or Siren — and adjust the volume to your preference.

Complete Privacy

All AI processing happens locally on your device. Your camera footage is never sent to any server, so there is no risk of personal data leakage.

No Install Required

Works instantly in Chrome, Firefox, Safari, and Edge. All you need is a PC or laptop with a webcam — nothing to download or install.
