Yahoo has launched an application to make it easier for people to plan their next trip. Called Yahoo Radar, it brings the company's search, communication, and content areas together to help you research your destination. With elements that you'd find in Kayak, TripIt, and TripAdvisor, this iOS app pulls from a variety of sources, including your inbox, to curate information about any U.S. city. Billed as a virtual travel guide assistant, Yahoo Radar adds artificial intelligence and machine learning to bring you the best recommendations for restaurants, activities, and attractions on your trip. As it's just been released, the first version of the app only lets you do research -- you can't book flights or accommodations or make other reservations, or even deep-link into third-party apps.
