Most people have smartphones and tablets (sometimes, in multiples) these days and don't actually need an intercom. But if you're looking for one and want something more feature-packed than your typical walkie-talkie-like variants, you may want to check out Nucleus. It's a touchscreen tablet/intercom that comes integrated with Amazon's virtual assistant Alexa and its many voice commands. You know how you can ask Alexa through Amazon Echo to add eggs to your grocery list, tell you the weather forecast or play Prime Music/iHeartRadio/TuneIn? Well, you can do all those with Nucleus, as well.
