As we’ve already noted, Google has now made ChromeOS 72 available which offers the ability to turn on Google Assistant for all supported Chromebooks.
After enabling Google Assistant, you can also customize how the assistant interacts with you and how much (or how little) it knows about you.
To locate the customization settings, find the Search and Assistant area in ChromeOS Settings.
Then, drop into the Google Assistant area and tap or click the Google Assistant settings option…
This area allows you to access specific customizations for Google Assistant such as things it knows about you, things specific to the assistant, and then other Services available to integrate with Google Assistant.
