Google Now, the intelligent personal assistant of Android will soon come to Chrome web browser for Windows and Chrome OS. A new flag has been added to the Chromium which allows users to enable the option if they know the relevant Google Now server. As the feature is not yet public, Google Now cards are not yet displayed.
Google also added a new notification center feature to Chrome OS which appears to hint at Google Now card support.
