'He also unveiled Allo, a new messaging service that will compete with Facebook's WhatsApp and Messenger products and feature a chatbot powered by the Google Assistant. Allo, like WhatsApp, will also have end-to-end encryption when it is rolled out this summer.
'Amazon's Echo, a surprise hit that has other tech giants racing to match it, uses a virtual assistant called Alexa, a cloud-based system that controls the Echo speaker and responds to voice-controlled commands by users.
'Like Alexa, Google Assistant can search the internet and adjust your schedule. However, Pichai said Google Assistant can use images and other information to provide more intuitive results.'
