The Google Now will be able to send messages using WhatsApp, Viber, WeChat, Telegram and NextPlus in English at launch, though Google plans to add more support for apps and languages in the future.

The users have to specify which app to use by saying 'OK, Google, send a WhatsApp message to ABC' and it will make and send the message through the proper service.

Google Now, an intelligent personal assistant developed by Google, is available within the Google Search mobile application for Android, and iOS, as well as the Google Chrome web browser on personal computers.

Google Now uses a natural language user interface to answer questions, make recommendations, and perform actions by delegating requests to a set of web services.

Along with answering user-initiated queries, Google Now proactively delivers information to the user that it predicts they will want, based on their search habits.

It was first included in Android 4.1 ('Jelly Bean'), which launched on July 9, 2012. The service was made available for iOS on April 29, 2013 in an update to the Google Search app, and later for Google Chrome on March 24, 2014.
