Google Now is an evolution of Google's search software that aims to predict what information a user will need and present it proactively. It uses a user's search history and habits to deliver personalized information like weather, traffic, package tracking, and event details through cards. On Android 6.0, Google Now gained an "On Tap" feature allowing contextual searches within apps by analyzing displayed text for keywords.

2. What it is?
Google Now is one of the more ambitious evolutions of Google's search
software. The idea is simple — predict what you'll want or need to know before
you know you need or want it, and serve it up in an easy-to-read format.
Google Now is available within the Google Search mobile application for
Android and iOS, as well as the Google Chrome web browser on personal
computers.

3. How it works?
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 to
users information that it predicts (based on their search habits) they may want.
The system leverages Google's Knowledge Graph project, a system used to
assemble more detailed search results by analyzing their meaning and
connections.

8. Google Now on Tap
On Android 6.0 "Marshmallow", Google Now supports an additional feature
known as "Google Now On Tap", which allows users to perform searches within
the context of information currently being displayed in an app. When a user
activates the feature, by holding the "Home" button or using a voice command,
the entire text content of the current screen is parsed to search for keywords
and other information (such as the names of people, television programs and
films, etc.), which is then used to generate cards that display information,
suggestions, and actions related to the content.
