(Telecompaper) Google has announced the launch of Allo, the messaging app first unveiled at its I/O conference in May that features artificial intelligence-powered response prompts and uses its new personal assistant software Google Assistant. The app's 'Smart Reply' feature suggests standard replies to messages based on context and learning the user's patterns; the reply may be text, emojis, stickers or photos. Smart Reply will improve over time and adjust to the user's style, said Google in a blog post. Google also added a Chrome-style 'Incognito mode' to Allo, with end-to-end encryption, discreet notifications and message expiration, to respond to growing concerns about privacy and security.
