Google Assistant is finally here, and it's more integrated on Pixel than any other assistant you've ever used on another device.

With the launch of Google's Pixel-branded smartphones, Google has officially unleashed Assistant in full form. The personal assistant is exclusive to the Pixel and Pixel XL, at least initially, bringing Apple Siri-like and Microsoft Cortana-like and Amazon Alexa-like functionality to the handsets. You can ask Assistant almost anything, and it will understand your words in context and serve up relevant results in a conversational manner.

Assistant even has a (female) voice - meaning Assistant can actually talk back to you, and yes, it'll have a sense of humour. To help you figure out everything Assistant does on the phone, we've rounded up some expert tips and tricks.

Browse them all below. But keep checking back to see what else we've added, because we plan to continually update this piece over time.

Google Assistant is Google's iteration of a personal assistant. It's considered an upgrade or an extension of Google Now, as well as an expansion of Google's existing "OK Google" voice controls. It's conversational, too. You can ask a question and follow-up questions, and Assistant will track the conversation, determine context, and audibly respond with the right information.

We've already spotted that the US and the UK currently offer up slightly different services in Google Assistant. This is likely to continue when Google Home launches. Currently, the UK doesn't offer the full collection of news services that the US does, but here we're listing tips and tricks for everyone - you just might not not be able to access them all right now.

When you first get your Pixel smartphone, power it on, and start setting it up, you'll be asked to use Google Assistant and "OK Google" always-on voice detection. You'll have to set up an "OK Google" voice model so that the phone can recognise your voice at any time and activate Google Assistant to serve your needs (whether that be to play music, fetch the weather forecast, or whatever).

Google Assistant feeds off your Google account, just as Google Now does. It's important to make sure that you setup Assistant with the the same account that you're going to be asking it to find information from, especially when it comes to photos. If you use one account for Assistant and a different account for your Google Photos, then it won't have access.

Google Assistant has a Settings menu. Under this menu, you can do everything from adjust your "OK Google" voice model to see a summary of your activity generated by Assistant. To access Assistant's Settings menu, open the Settings app, and then go to Google > Search & Now > and Settings (under Google Assistant). From there, you'll see several submenus with settings options.

Alternatively, from any screen including the home screen, hold down the Home button, then tap More button (three vertical dots) in the top left of the Assistant screen, and select Settings.

Under the Assistant's settings, scroll to "Adjust settings for this Pixel device". Beneath that, you'll see a toggle next to Assistant. When you turn on the toggle, you give Assistant permission to answer questions and get things done.

Under the Assistant's settings, scroll to "News" beneath the Pixel section. Tap it to customise your news list. You'll have to hit the customise link on the next screen, but then you can select a bunch of news sources, including NPR, PBS, CBS, and more. After you select which news sources you'd like to hear from, you can ask Assistant to narrate the news for you. This isn't currently available in the UK.

Under the Assistant's settings, scroll to "My Day" beneath the Pixel section. Tap it to customise your daily briefing. You can select from a handful of options, including weather, work commute, reminders, whether you'd like to end your day with a narration of the news. After you're done, you can ask Assistant for a readout of your day and get responses interesting to you.

In the UK, you currently only get the time and weather.

Under the Assistant's settings, scroll to "Shopping List" beneath the Pixel section. Tap it to access your Shopping List via the Google Keep app.

This isn't currently enabled in the UK: asking to view your shopping list in the UK gives you an error from the US voice, which is strange.

Under the Assistant's settings, scroll to "Adjust settings for this Pixel device". Beneath that, you'll see a toggle next to "Use screen context", which is basically Now on Tap 2.0. When you turn on the toggle, you give Assistant permission to show you info related to what's on your screen. It might show you relevant links in YouTube or IMDB, for instance.

Under the Assistant's settings, scroll to "Adjust settings for this Pixel device". Beneath that, you'll see "Assistant Language". Tap it to see Language Preferences, where you can select your default language and add a language.

Under the Assistant's settings, scroll to "Adjust settings for this Pixel device". Beneath that, you'll see "'OK Google' detection". Tap it. From there, turn on the toggle for "Say 'OK Google' any time" to give Assistant permission to recognise your voice whenever you say "OK Google" - even if your screen is off or you're using an app. This makes Assistant always-on.

Under the Assistant's settings, scroll to "Adjust settings for this Pixel device". Beneath that, you'll see "'OK Google' detection". Tap it. From there, turn on the toggle for "Trusted Voice" to give Assistant permission to unlock your device when it hears you say "OK Google" (the sound you make must match your previously recorded "OK Google" voice model, however).

Under the Assistant's settings, scroll to "Adjust settings for this Pixel device". Beneath that, you'll see "'OK Google' detection". Tap it. From there, tap "Retrain voice model". You'll then have to re-say "OK Google" a few times so that Assistant can remember and recognise how you say the phrase. It can then use the phrase as a wake word and device-unlock word.

Under the Assistant's settings, scroll to "Adjust settings for this Pixel device". Beneath that, you'll see "'OK Google' detection". Tap it. From there, tap "Delete voice model" so that Assistant can't remember and recognise how you say the phrase. Keep in mind you then can't use the phrase.

Under the Assistant's settings, scroll to "Adjust settings for this Pixel device". Beneath that, you'll see "'Voice". Tap it. From there, turn on the toggle for "Block offensive words" so that Assistant will recognise (and won't hide them either) in voice results.

Under the Assistant's settings, scroll to "Google Account settings". Beneath that, you'll see "'Personal info". Tap it. From there, you'll see the option to add your Home and work locations. Tap it, and then manually enter your addresses. If you've been using Google Now previously, this information will probably already be in place.

Under the Assistant's settings, scroll to "Google Account settings". Beneath that, you'll see "'Personal info". Tap it. From there, you'll see the option to add your nicknames. Tap it, and then manually enter your nicknames. You can also test that Google knows how to say it correctly.

Under the Assistant's settings, scroll to "Google Account settings". Beneath that, you'll see "'Personal info". Tap it. From there, you'll see the option to change your weather units. Tap it, and then select from Fahrenheit or Celsius.

Under the Assistant's settings, scroll to "Google Account settings". Beneath that, you'll see "'My Activity". Tap it. From there, a screen will pop up showing you all the "control data generated by your Assistant".

Google Assistant is your personal assistant. It can play music for you, set reminders, check your flight, and more. Here's a few things you can say and do with Assistant using just your voice. You just have to say "OK Google" or press and hold the Home button on the Pixel phones to access Assistant.

To ask Assistant to play some music, say "OK Google" followed by "play some music", "play some Jazz", "play some workout music", "listen to Daft Punk", or "listen to Imagine on Spotify", etc.

If you have more than one music app, it will give you the option of the service you want to use, open it up and start playing. If you're playing Spotify on another device, Google Assistant can still control what you play, too.

To ask Assistant to look at your calendar, say "OK Google" followed by "what's on my calendar".

To ask Assistant to show your Google Photos, say "OK Google" followed by "show me my photos". Google Photos knows that photos contain, so it will also return photos of objects, like your dog, food, kids or places, just say "show my pictures of cars" and you'll get your car photos displayed.

The universal method of decision making. Say "OK Google" and then "toss a coin". Assistant will toss that coin and let you know if it's heads or tails.

"OK Google" then "turn on flashlight" will turn on the flash on your phone. Great for peering into dark holes.

This the perhaps the jewel in the crown of Google Assistant's skills. Say "OK Google" followed by "I'm feeling lucky". We won't ruin the surprise, but Google Assistant really goes to town in dealing with Google's iconic question. 

Try asking Google Assistant "when am I?"
