Free Guide to Opening Google Assistant on Your Devices

What Is Google Assistant and Where You Can Use It

Google Assistant is a voice-controlled helper made by Google that works on many types of devices. Instead of typing, you can talk to Google Assistant to ask questions, get information, or control things in your home. According to Google's own reports, Google Assistant is available on more than one billion devices worldwide as of 2024. This includes smartphones, tablets, smart speakers, smart displays, smartwatches, and even some televisions and car systems.

The core function of Google Assistant is to listen when you say "Hey Google" or "OK Google," then process your spoken words and provide answers or complete tasks. For example, you might ask it what the weather is, play music, set a timer, call someone, send a text message, or turn off your lights if you have smart home devices connected. Google Assistant works in over 100 languages and dialects, making it a tool used by people around the world.

Different devices offer different capabilities with Google Assistant. On a smartphone, you get voice commands plus the ability to see results on your screen. On a smart speaker like Google Home, you only hear responses out loud. On a smart display with a screen, you see information visually. Some devices let you use both voice and touch controls, while others work only by voice. Understanding what device you have will help you know what features are available to you.

Google offers its Assistant service at no cost. There are no subscription fees or hidden charges to use the basic features. However, some additional services—like streaming music from certain apps or certain smart home features—may require paid subscriptions to those separate services. The Assistant itself, as a tool, remains free to use on any compatible device.

Practical Takeaway: Before opening Google Assistant, identify what device you want to use it on. Write down the device type (smartphone, smart speaker, tablet, etc.) so you can follow the specific steps for that device.

Opening Google Assistant on Android Phones and Tablets

Android devices—phones and tablets made by companies like Samsung, Google, OnePlus, Motorola, and others that run Google's Android operating system—have several ways to open Google Assistant. The most common method is speaking the wake words "Hey Google" or "OK Google" out loud. Your device listens for these words constantly (if you have enabled this feature), so you can activate Google Assistant from almost anywhere on your device without touching the screen.

If voice activation isn't turned on or you prefer not to speak, you can also open Google Assistant by pressing and holding the home button. On most Android phones, the home button is the circle or icon at the bottom center of your screen. Hold it down for about one to two seconds until Google Assistant appears. Another method is to swipe up from the bottom corners of your screen—on some Android devices, swiping up diagonally from either bottom corner opens Google Assistant immediately.

You can also search for Google Assistant in your device's app list. Swipe to your apps screen, look for an icon labeled "Google" or "Google Assistant," and tap it to open the application. On many devices, you'll find it already installed and ready to use. If for some reason it isn't on your device, you can visit Google Play Store, search for "Google Assistant," and install it directly.

To enable the "Hey Google" voice activation feature on Android, open Google Assistant by any method above, then look for settings (usually a gear icon or three dots). Search for "Voice activation" or "Hey Google detection" in the settings menu. Toggle this feature on. You may need to train your device to recognize your voice by saying a few phrases. After setup, your device will recognize the wake words from across the room.

If you want to turn off Google Assistant, visit your device's Settings app, find "Apps" or "Application Manager," locate Google, and select "Disable" or "Turn Off." Note that disabling Google Assistant may prevent some Android features from working correctly, so most people leave it turned on and simply don't use it if they prefer not to.

Practical Takeaway: Try the voice wake words "Hey Google" or "OK Google" first. If that doesn't work, press and hold your home button. These two methods work on nearly all Android devices and require no additional setup.

Opening Google Assistant on iPhones and iPads

iPhone and iPad users can access Google Assistant, but the experience differs slightly from Android devices because Apple's Siri is the built-in voice assistant. To use Google Assistant on an iOS device (iPhone or iPad), you need to download and install the Google Assistant app first. Visit the Apple App Store, search for "Google Assistant," and tap "Get" to download it. The app is free and made by Google directly.

Once installed, you can open Google Assistant by tapping the app icon on your home screen, just like any other app. The app will open to the main Google Assistant screen where you can speak your command or type your question. Unlike on Android, there is no automatic "Hey Google" wake word on iPhones and iPads—you must manually open the app first or use Siri to launch it.

Some iPhone users set up a shortcut so they can open Google Assistant more quickly. You can create a custom voice command in Apple's Shortcuts app that opens Google Assistant with a single spoken phrase. To do this, open the Shortcuts app (built into iOS), create a new shortcut, add the action "Open App," select Google Assistant, and save it. Then you can activate it by saying "Hey Siri, [your custom phrase]."

Another method is to add a widget to your iPhone or iPad home screen. Widgets are small app previews on your home screen that let you access certain app features without opening the full app. If Google Assistant offers a widget, you can long-press your home screen, select "Add Widget," find Google Assistant, and add it. Then you can tap the widget to open Google Assistant quickly.

If you prefer not to use Google Assistant on your iOS device, simply delete the app. Removing it takes no additional steps—just press and hold the Google Assistant app icon, select "Remove App," and confirm. You can always reinstall it later from the App Store if you change your mind.

Practical Takeaway: iPhone and iPad users must download the Google Assistant app first from the App Store. After installation, tap the app icon to start using it. There is no automatic voice activation like on Android, so you'll open it manually each time.

Opening Google Assistant on Smart Speakers and Smart Displays

Smart speakers—devices like Google Home, Google Nest, or other Google Assistant-powered speakers—activate Google Assistant by default and have no app to open. These devices are built specifically to run Google Assistant, so the service is already active when you plug them in and set them up. To use Google Assistant on a smart speaker, simply speak the wake words "Hey Google" or "OK Google" from across the room. The device listens constantly and responds when it hears these words.

The setup process for a new smart speaker involves connecting it to power, opening the Google Home app on your phone, and following the setup wizard. The Google Home app is available free on both Android and iPhone. During setup, you'll connect your speaker to your Wi-Fi network, sign in with your Google account, and configure your preferences. After setup is complete, your smart speaker is ready to use immediately—no additional steps are needed.

Smart displays—devices with screens like Google Nest Hub or Google Home Hub—work the same way. They respond to "Hey Google" or "OK Google" voice commands, but they also show visual information on their screens. You can see weather forecasts, calendar events, shopping lists, recipe instructions, and video results displayed as you use them. Like smart speakers, smart displays have Google Assistant built in and don't require an app.

To control a smart speaker or smart display, you can speak commands like "Hey Google, what's the weather?" or "OK Google, play jazz music." You can also touch the screen on smart displays to interact with results or adjust settings. Most smart speakers and displays have physical buttons on top or side for volume control and a mute button to turn off the microphone if you prefer privacy.

If you want to review or change settings on your smart speaker or display, use the Google Home app on your smartphone. This app shows all your devices, allows you to adjust volume and music settings, create routines (sequences of actions that happen when you give one command), and manage connected smart home devices. You don't open Google Assistant through this app—the app is just for managing
