But between Alexa, Google Assistant, Google Nest Mini, the Amazon Echo Dot, and more, it's easy to get confused over which device does what and so forth.

For devices designed to make our lives easier, it shouldn't be so complicated - so see below for a nice, clear explanation of what exactly this new smart tech is.

What is Alexa?

Alexa Echo smart speakers

Alexa is a virtual assistant AI - essentially a digital voice that can recognise spoken commands and then talk back, meaning it can answer questions and perform certain tasks such as playing music.

Alexa is most commonly found in the Amazon Echo, a series of speakers that use the Alexa software. As we explained in our article on the difference between Alexa and Echo, people have a tendency to just call their Echo speakers Alexa - when in reality Alexa is just the name of the virtual assistant housed within the Echo, and not a physical product.

However, the success of Alexa means it is now found in several third-party speakers, TVs and even cars. For more information see our list of Amazon Echo accessories.

What does Alexa do?

Much like Apple's virtual assistant Siri, Alexa can answer questions, set alarms, make to-do lists, and read out the news, all by the command of your voice alone.

As Alexa is often found inside a speaker it can also play music, audiobooks, and podcasts - either through BlueTooth or directly streaming from the internet - and also has access to the Amazon store, meaning you can order items from the retail giant just by talking.

A growing use of Alexa is linking it with other available smart home tech, such as lightbulbs, thermostats, blinds and security systems. This means you can ask Alexa to turn off the lights, change the temperature or close the blinds, and the task will be performed without you having to lift a finger.

Alexa also has a few neat tricks that its competitors lack - it has a Guard Mode to listen out for intruders, can plug into your car via USB and can even tell when you're annoyed and apologise.

Is there a monthly cost to use Alexa?

In short: no! No matter what Alexa-powered device you are using there's no monthly subscription in order just to use Alexa. So once you've bought your Amazon Echo or other compatible tech, you're free to use it as much as you like without yet another monthly outgoing.

However, if you wish to use a music streaming service on your Alexa device - such as Spotify, Amazon Music or Apple Music - that will likely require a monthly subscription to use. However, you can BlueTooth songs to your Alexa for free.

Is Alexa compatible with Google Home?

No – while Alexa can communicate with other Alexa-powered speakers, it is not compatible with rival Google Home. There are all sorts of other devices it can connect to, however, however, including smart doorbells and even smart plugs.

Is Alexa compatible with Fire Stick or Google Chromecast?

Unfortunately, you can't connect your Alexa to Google Chromecast - the streaming stick is only compatible with other devices from the internet giant such as Google Nest Mini.

Most Fire TV Sticks come with Alexa built into the remote these days, but you can connect your Alexa speakers to your Fire Stick. You simply have to link the two in the Alexa app (Settings > TV & Video > Fire TV), you can launch Prime Video shows and pause, rewind, and fast-forward your TV with your voice.
