Google Now notifications will now be available on Google’s Chrome browser, being slowly pushed out today.
Google Now Notifications in Chrome:
Launched as part of Android OS Jelly Bean, Google Now will give you updates about travel, weather, sports, and news through the application accessed through tapping and holding the home button and dragging up (or press the correct icon). If set in the settings, these updates can also be shown in the Notification area.
As of today, Google Now notifications in Chrome will slowly be pushed to all Google browsers and Google laptops. There is no need to do anything special, no extension to download, when it’s pushed to your Chrome browser, it will be visible in the Chrome Notifications (which is found in the Menu Bar on Macs, or in the Notification area on Windows), as long as you sign into Chrome with the same account on both your Android and Chrome. The announcement from Google, shared on their Google + page, didn’t say much about what will be shown, but it’s a fair guess that it will be much like the notifications shown on your Android device.
If you’re not a fan of Google Now (or simply don’t use it), then you can disable the notifications (when they come) by going to the Chrome Notification Centre and un-ticking the appropriate app, which I found out via the support page for Google Now Chrome notifications.
