Google Assistant is one of the most widely used voice assistants in the world. Although it supports a wide range of products including smartphones, smart displays, smart speakers, and other smart home devices, support for desktop PCs has always been a hassle. Google has not shown interest in bringing Assistant to desktops and laptops, with the exception of Chromebooks. If you’re someone who’s looking for a way to use Google Assistant on your Windows, macOS, or Linux machine, there’s good news. A Chennai-based developer Melvin. L. Abraham has built an unofficial cross-platform Google Assistant desktop client based on Google Assistant SDK. Today, we’ll be showing the steps involved to set it up and use Google Assistant on your PC.

Use Google Assistant on Windows, macOS, and Linux

The process to enable Google Assistant can seem a bit complicated at first glance. However, if you spare a few minutes to follow the steps, you can easily set it up and start using Google Assistant to control your PC. Another aspect worth mentioning is that this client is under development, and hence, you may experience occasional bugs while using it.

1. Register Device for Using Google Assistant on PC

1. To get started, download the latest version of the desktop client from GitHub to your PC. I’m using a Windows 10 machine for this demonstration, but you can download the one based on your system’s operating system.

2. Install the Assistant app on your PC. At this stage, it won’t work on your PC and you should configure the backend first. To do that, open the Actions Console from your web browser and click on ‘New Project.’ You should log in with your Google account to access Actions Console.

3. Go through Google’s terms of service, choose the ‘Yes’ toggle, and click on ‘Agree and continue.’

4. When the New Project popup appears, set a new project name, choose the language and your region. After filling in these details, click on the ‘Create project’ button.

5. Soon after you click Create project, a page to help you set it up appears. From here, scroll down and you’ll notice an option for device registration. Click on the ‘Click here’ hyperlink.

7. You should now set the product name, manufacturer name, and device type. The developer says that you can set any device type. I’ve used TV as the device type and you can choose any other device type if you prefer. Once done, click on the ‘Register Model’ button.

8. We’ve now reached an important step where you should download the key file. This will be a ‘.json’ file and you’ll need this file later to configure the client. Click on the ‘Download OAuth 2.0 credentials’ button to download this file.

2. Enable Google Assistant API and Setup Consent Screen

1. Open Google Cloud Platform’s Console and click on the drop-down menu next to GCP’s logo in the top-left corner.

3. Setup Google Assistant Client Authentication

You’ve now prepared your PC to run Assistant as you’ve already completed device registration and configured the consent screen of the API. With a few additional steps, you can start using Google Assistant on your PC.

1. Open the Google Assistant client that you installed and head to the Settings by clicking on the gear icon in the top-left corner of the app.

2. You should now use the OAuth 2.0 credentials .json file that you previously downloaded. Click on the Browse button under the Authentication section and set the JSON file’s path to ‘Key File Path.’ You can leave the ‘Saved Token Path’ empty.

3. After setting the path, click on the Save button.

4. The app will now prompt if you’d like to automatically set the saved tokens path. Click on the ‘Automatically set a path’ option to go ahead.

4. Google Assistant Client Impressions

Although unofficial, the Google Assistant client is designed well. It looks elegant, has rounded corners, and you can resize the app horizontally and vertically. You can use the app to issue a variety of basic voice commands, including searches, checking the weather, and smart home controls. On Windows machines, you can access the client with the keyboard shortcut ‘Windows+Shift+A.’

On the app’s settings page, you get the options to tweak several aspects of the app to suit your preference. For instance, you can choose to keep the app always on top of other apps for quick access. In case you want a light theme, you can switch themes from settings.

I also tried playing a few Google Assistant games to test its capabilities and it worked just fine. Below is the Google Assistant game ‘Are you feeling lucky?’ through Assistant on a Windows 10 PC:

However, there are a bunch of caveats. You can’t use the app to play music from music streaming services, play YouTube videos or Netflix movies and TV shows, or launch apps. In addition, you can’t use the Hey Google / Ok Google command to trigger the Assistant. Instead, you’ll have to manually open the app to type or use voice commands. That said, hotword detection is on the to-do list of the project, and it may come in the future.

Try Google Assistant on your PC

If you’re interested to contribute to this open-source project, you can do so from the project’s GitHub page. It remains to be seen if Google ever creates desktop Assistant clients for other platforms, but until that happens, you can check this out and see if you find it useful. To test all the capabilities of the app, take a look at our best Google Assistant tricks article and try them out.
