Think of Alexagate as a little hat that sits on top of your home Amazon Echo and jams the Echo’s microphone. Amazon Echo units ordinarily record and save all audio that they hear in your house, effectively wiretapping your home 24/7. Alexagate prevents this from happening. Alexagate prevents your Echo from hearing you. Clap three times, or tap the Alexagate three times, and it toggles off so that you can talk to your Echo like normal. Claps three times again, and you’re once more assured of privacy. Alexagate uses pulsed ultrasound to jam the Echo’s microphone. What’s even better: Ultrasound is beyond the range of adult human hearing, so you won’t even be able to tell it’s happening!
