We use ambient unpredictable noise from your microphone as an entropy source.
Real-world noise is genuinely unpredictable — and, unlike an opaque chip or unknown firmware, nothing about where it comes from is hidden from you. We also mix in your browser's own secure randomness, so the result stays strong either way.
Under your control.
Activate your microphone.

– the system collects good frames until it has 2M+ of validated bits, then generates automatically.
Target: 128 bits. Everything stays on this device.
The mic is routed to your speakers so you can hear what it hears — a little feedback loop that makes the result harder to reproduce. Too loud or squealing? Turn down your system volume or press Monitor to mute.
