At the very beginning of this process, you need to visit , which is a developer platform for Google Assistant. Once there, Click on the New Project button.

The next step is naming your Google Assistant project. Pick a name you like – it really doesn’t matter – choose your region and when you’re ready, click on Create project.

On the following site, look to the bottom of the page and find the “Are you looking for device registration? Click here” option and click on it.

Next, you’ll be taken to the register page. Click on the blue REGISTER MODEL button and continue on.

In the pop-up window, you’ll be prompted to give the product – that is your own version of Google Assistant – a name and a manufacturer. Again it does not matter what you put there. In the device type, you can also put anything from the list.

Now is a very important part. The next window will prompt you to download OAuth 2.0 credentials. Click on the blue bar to download it and save this file in a safe place – you’ll need this later.

The next step is visiting the website. There, in the top-left corner, you’ll find a prompt to select a project. Click it and in the pop-up window select your new Google Assistant project. Once it’s selected, click Open.

Once that’s done (you’ll see the previous Select a project prompt change into the name of your project) you can click on the APIs and services tab from the menu on the left.

In this menu, next to its name, you’ll find a + icon and a prompt to enable APIs and services. Click on it.

You’ll be taken to another page with a search bar. In there, type “Google Assistant API” and hit search.

On yet another page you can find the results of your search – there should be only one. Click on the Google Assistant API result by Google.

Once you click it, you can click on the blue Enable button to turn this API on.

You’ll be taken back to APIs and Services menu. From here, on the left click on the Credentials menu. There you’ll find a Configure consent screen button. You should click it.

You’ll be asked to configure the type of the user of your app. First, choose External user, and once that’s done – click Create.

The next page is there to configure your consent page. There you’ll have to input your email twice – once in the User support email space, and once in the Developer contact information space. Once you do that, navigate to the bottom of the page and click Save and Continue.

You’ll be taken to Scopes menu – you should skip that and just select Save and Continue at the bottom

Now it’s time for the Optional info tab. Skip that as well and select Save and Continue again.

The next page is there for you to make sure that all the info so far is correct. If it is, simply click Back to Dashboard at the bottom.

Back at the dashboard, you can scroll down and find the Test users tab. There, click on the Add users button.

You’ll be greeted by a pop-up window where you can add the email addresses of testers for your app. Add your email into the box and click save once you’re done.

Now it’s time to finally download the Google Assistant app itself. Once again, it is not an official app, so everything you do here you are doing at your own risk. However, it seems to be secure and is maintained by a community of enthusiasts. To get it, and download Google-Assistant-Setup-1.1.0.exe from the list.

Once the .exe file is downloaded, you can run and install it. Once you’re done installing, choose the Run Google Assistant tickbox in the setup and click Finish.

This is the first time that you’ll run Google Assistant, but you’re not yet ready to use it. To set it up, click Get Started in the bottom left corner.

IMPORTANT: If, for some reason, the app does not start itself, you can also run it from the shortcut on your desktop or just by using a keyboard shortcut Windows+Shift+A

There, you’ll be informed about the limited capabilities of this build of Google Assistant. Once you’re ready to go on, click Proceed.

You’ll now be prompted to provide an authentication file. To do so, you’ll need to go into settings, which are accessible through the cog icon in the upper left corner.

Here, you’ll have to provide your OAuth credentials. Simply click Browse next to the Key File Path and choose the file that you’ve downloaded in Step 6. Once you do that, click Save.

You’ll now be asked to set a path for your Tokens. Simply click on “Automatically set a path” in the pop-up window.

You’ll now be asked to relaunch the app for the changes to be accepted. Do so by clicking the Relaunch Assistant button in the bottom left.

Once the app relaunches, you should be greeted by your browser opening a new window with a Google authentication site. You should log in with the same Google account that you’ve used as a test user and agree to sending your information the your app. Once you confirm twice, you’ll be given your token, which you should now copy.

IMPORTANT: Here you might encounter a problem with authentication, where instead of being prompted to get a token, you’ll be informed that your authentication has failed. If you encounter that bug, simply to resolve it. There are also steps there to follow if you cannot get through the agreement process with your Google account.

Now return to the Assistant app and input your new token into the empty field. Once it’s done, click Submit.

Once again you’ll be asked to relaunch your Google Assistant app because of the changed token. Do so by clicking the Relaunch Assistant button in the bottom left.

Finally, after relaunching, your new assistant is ready to go! You can start using it by typing your queries into the box at the bottom or using voice input by clicking the microphone icon in the bottom right. If you want to change some options – for example enable “Hey Google” voice prompts, you can do so in the settings menu, which is located – as before – behind the cog icon in the upper left corner. Once you’re happy with your settings – it’s your (and your Assistant’s) time to shine!
