"Search Live is designed for those moments when you need real-time help, and typing out a query just won't cut it. If you want to ask about something in front of you, like how to install a new shelving unit, you can enable your camera to add visual context. This way, Search can see what your camera sees and offer helpful suggestions, plus links to more information on the web."
Google is bringing Search Live to everyone in the US, letting you search for information by having a conversation with an AI assistant. When you use the feature, Search Live will respond to your questions in real-time, as well as surface relevant links from the web. You can try the feature out by opening the Google app on Android and iOS, and then selecting the new "Live" button beneath the search bar.
