Kitchen-table Lab
Listening eye
Does the device see you? No. Does it hear you? Yes — and this eye shows that.
Privacy: Sound stays in your browser. No server, no storage, no ChatGPT. Only your microphone + Web Audio to measure volume. Close the tab and the eye closes.
Tip: Whisper, clap your hands, sing. The eye reacts to volume — not to what you say.
Why this gimmick?
Smart speakers, baby monitors and AI teddies often have no screen. You cannot see when they listen. This eye makes it visible: when the eye is open, your microphone is on. When it is closed or you close the tab, the microphone is off.
With real products, audio sometimes does go to the cloud. This demo does not: it is a kitchen-table trick.
