The fastest way to open Google Assistant

On most Android phones, hold down the home button (the circle at the bottom center of your screen) for about two seconds. Google Assistant will open at the bottom of your screen and ask "What can I help you with?" On iPhones, you cannot use Google Assistant the same way — you need to open the Google app first, then tap the microphone icon at the bottom.

On a computer, go to google.com in your web browser, then click the microphone icon in the search box. You can also say "Hey Google" if your computer has a microphone and you have turned on voice set up in your Google account settings.

If the home button method does not work on your Android phone, your device may not have Google Assistant turned on yet, or your phone manufacturer may have changed the default button. In that case, open the Google app (the colorful "G" icon) and tap the microphone icon at the bottom of the screen.

Key Takeaways

  • On Android phones, hold the home button for two seconds to open Google Assistant without opening any app first.
  • On iPhones, open the Google app and tap the microphone icon, since iPhones use Siri as the default voice assistant.
  • On computers, click the microphone icon in the Google search box or say "Hey Google" if voice set up is turned on.
  • If the home button does not work, open the Google app directly and use the microphone icon there instead.

Why you might want to use Google Assistant instead of typing

Google Assistant listens to what you say and tries to understand what you want — whether that is a weather forecast, directions, a calculation, or a reminder. You do not have to type anything. This is useful when your hands are full, when you are driving, or when typing would take longer than speaking.

Google Assistant also learns some of your preferences over time. If you ask it to play music, it remembers which music service you use. If you ask for directions, it knows your home address (if you have saved one). This means repeated requests get faster.

What Google Assistant can and cannot do

Google Assistant can answer factual questions ("What is the capital of France?"), set reminders and alarms, control smart home devices (if you have them connected), send text messages, make phone calls, play music or podcasts, and search the web. It can also read your calendar if you have given it permission.

Google Assistant cannot access your email, your banking apps, or your private messages unless you explicitly give it permission to do so. It also cannot make purchases or transfer money on its own — it can only show you information or open an app where you can do those things yourself. If you ask it to do something it does not understand, it will usually search the web for an answer or ask you to clarify.

Turning Google Assistant on if it is turned off

On Android, open the Google app, tap your profile picture in the top right corner, then go to Settings. Scroll down and tap "Google Assistant." If you see a toggle that says "Google Assistant," make sure it is turned on (it should be blue or green, not gray).

On iPhone, open the Google app and tap the microphone icon. If you see a message saying Google Assistant is not available, you may need to update the Google app. Go to the App Store, search for "Google," and tap "Update" if you see it.

On a computer, Google Assistant is usually available by default in the search box. If the microphone icon does not appear, try using a different web browser like Chrome, which works best with Google services.

Privacy and what Google Assistant records

When you use Google Assistant, Google records what you say and stores it in your Google account. You can listen to these recordings and delete them if you want. Go to myactivity.google.com, click "Google Assistant" on the left side, and you will see a list of everything you have asked.

You can also turn off recording for future requests. On Android, open the Google app, tap your profile picture, go to Settings, then "Google Assistant," then "General," and toggle off "Voice and Audio Activity." On iPhone, open the Google app settings and look for privacy or voice options. On a computer, go to myactivity.google.com and click the settings icon to manage what gets saved.

Google Assistant does not record anything if you do not say "Hey Google" or press the microphone button first. The microphone only listens for that wake phrase when you have voice set up turned on.

Troubleshooting when Google Assistant will not open

If holding the home button does not work on Android, your phone may have a different setup. Try opening the Google app directly and tapping the microphone icon instead. Some phone makers like Samsung replace Google Assistant with their own assistant (Bixby), so you may need to change your default assistant in settings.

If the microphone icon does not appear on your computer, make sure you are using Google Chrome or another modern browser. Older browsers sometimes do not support the microphone feature. You can also try clearing your browser cache (the stored data that speeds up websites) and refreshing the page.

If Google Assistant opens but does not respond to your voice, check that your microphone is not muted. On phones, look for a mute switch on the side of the device. On computers, check your browser settings to make sure the website has permission to use your microphone.

Frequently Asked Questions

Can I use Google Assistant without saying "Hey Google"?

Yes. You can open it by holding the home button on Android, tapping the microphone icon in the Google app, or clicking the microphone icon in the search box on a computer. You only need to say "Hey Google" if you have voice set up turned on and want to use your hands-free.

Does Google Assistant work offline?

Some basic commands work without internet — like setting a timer or alarm — but most features need a connection. Searches, directions, and music streaming all require internet. If your phone loses connection, Google Assistant will tell you it cannot complete your request.

Is Google Assistant the same as Google Search?

No. Google Search is a website where you type questions and get results. Google Assistant is a voice tool that understands natural language and can control your phone or smart devices. You can use Google Assistant to search, but it does more than that.

What is the difference between Google Assistant and Siri?

Siri is Apple's voice assistant built into iPhones and iPads. Google Assistant is Google's version. On iPhones, Siri is the default, but you can still use Google Assistant by opening the Google app. Each one has different features and integrations with their company's services.

Can I delete my Google Assistant history?

Yes. Go to myactivity.google.com, click "Google Assistant," and you can delete individual recordings or all of them at once. You can also set it to auto-delete older recordings — go to your Google account settings and look for "Data & Privacy" to set a deletion schedule.
