Google this week unveiled Smart Reply for Gmail on iOS and Android. It uses machine intelligence and neural networks to suggest up to three possible responses for incoming email, based on the content of those emails. The system learns from users' responses to suggestions to fine-tune its offerings. It has a repository of 20,000 Smart Replies that will continue to grow with time, said Google spokesperson Emma Ogiemwanye. Smart Reply will be available in English in Google Play and Apple's App Store.by 208headlines
