Digital assistants like Amazon Alexa are all the rage these days. Their concept is easy to understand, but you have to put in some work to get the most out of them. Each has its own set of features you have to figure out to know what the assistant can and can’t do.

That’s what this guide is for. It will teach you more or less everything you need to know about Amazon’s Alexa. That includes precisely what Alexa is, how to use it, what devices it supports, and much more. Let’s dive in.

Amazon Alexa guide:

What is Amazon Alexa?

Alexa is Amazon’s virtual assistant. It mainly competes with Google Assistant and Apple’s Siri. Alexa is available on various devices, including smartphones, smart speakers, and smart displays. It lets you check the weather, play music, and control smart devices in your home with voice commands. The service is there to help you get stuff done faster and easier, without the need to push a bunch of buttons or tap on a screen several times.

Alexa made its debut in 2014 on Amazon’s Echo speaker. In addition to Amazon’s lineup of devices, it’s also available on many products from third-party manufacturers. Let’s dig right in to find out more.

How to use Amazon Alexa?

fitbit versa 2 review

Using Amazon Alexa on a smart speaker is a breeze. Most Alexa-powered devices are always listening, and you can get their attention by using a wake word of choice: Alexa, Echo, Amazon, Ziggy, or Computer. The default wake word is “Alexa,” but you can change the wake word within the Alexa app by going to More > Settings > Device settings, selecting your device from the list, tapping on the gear icon, and hitting the Wake Word option.

To use Alexa on a smart speaker, say the wake word followed by a command. An example of this would be, “Alexa, tell me what the weather is like.” Some older devices like the Amazon Tap required you to push a button to wake them up, so they weren’t completely hands-free.

Using Amazon Alexa on smartphones isn’t quite as good as on smart speakers. The smartphone app supports wake words, but only when the Alexa app is open and running. Additionally, the feature has to be turned on in the settings. Just open the Alexa app and go to More > Settings > Device Settings> Alexa on this Phone and toggle Enable Alexa Hands Free on. Otherwise, you will have to open the app and tap on the Alexa button to use voice commands.

Using Alexa on any other gadget like a camera or media streaming device works the same. You have to use a wake word or press a dedicated button to get the device’s attention and then boss it around with various commands. Keep in mind that not every device supports all features.

Alexa-powered devices

The most popular Alexa-powered devices are Amazon’s Echo smart speakers. There are also several non-Amazon smart speakers available from brands like Sonos and Ultimate Ears.

Next up are Amazon’s Fire tablets and media streaming devices, which turn your dumb TV into a smart one. Alexa also comes pre-installed on a few smartphones, but you can download it from the Play Store on any Android handset running 5.0 Lollipop or higher. Other devices that have Alexa built-in or are just compatible with Amazon’s assistant include thermostats, lamps, smartwatches, security cameras, smart plugs, and many others. There are too many products to list in this post, so we’ve rounded up some of the best and most interesting ones below.

Not all of these commands work on every device, and you’ll have to enable Alexa Skills to use some of them.


Amazon Alexa skills what's the time

Skills are what make Amazon’s digital assistant shine. They are third-party apps that bring new functionality to Alexa.

You can browse and enable Skills in the Alexa app by going to Menu > Skills & Games. More than 100,000 of them are available, and they’re all free, though some offer premium features. We’ve compiled a list of a few excellent Alexa skills, which you can check out below. Visit Amazon’s website to discover even more.

Smart home products

Just like Google Assistant, you can use Alexa to control compatible smart devices in your home. These include lights, thermostats, and cameras, among many others. All of Amazon’s smart speakers allow you to control other smart devices with voice commands.

To connect your smart devices with Amazon’s digital assistant, launch the Alexa app and enable the Skills for all the smart products you have in your home. Open the menu, select Skills & Games, and use the search box on top to find the Skills you’re looking for. After you enable them, select “Add Device” from the menu of the Alexa app or say “Alexa, discover my devices.” Then follow the on-screen instructions to get things up and running.

Smart home products compatible with Amazon’s digital assistant carry a “Works with Alexa” badge. This means you can’t control them with voice commands directly like products with the digital assistant built-in, but you can control them via smart speakers or the Alexa app on your phone. Amazon has a dedicated Works with Alexa page on its website, where you can check out loads of other cool products.

Amazon Alexa vs Google Assistant

Amazon Alexa and Google Assistant are similar in many ways. They both allow you to control various devices with voice commands. You can quickly check the weather, play music, ask questions, and so forth. Both are also available on smartphones, smart speakers, and tons of other products.

However, the best way to think about the differences between the two is that Alexa is mainly a smart home hub and a way to interact with third-party services. Google’s Assistant is much closer to a true personal assistant, keeping track of the little details you might need throughout your day.

I often use Assistant on my smartphone to create reminders, set alarms, do Google searches, and ask random questions. I’m very happy with the service. I can’t say the same for using Alexa on a smartphone.

During testing, I couldn’t do all the things I’m used to on Assistant. Opening the app every time I want to use Alexa is also a pain. Assistant is a far superior option on Android devices, in my opinion. Still, the difference between the two gets smaller when talking about smart speakers connected to other smart gadgets in your home.
