CNBC, citing several people familiar with the matter, said that Facebook has been working on the new voice assistant since early 2018 but it's "unclear how exactly Facebook envisions people using the assistant." It could be used in Portal, its virtual reality headsets or for other projects. Facebook's Portal currently taps into Amazon's Alexa. 

Facebook employees in Redmond, Washington and Ira Snyder, director of AR/VR and Facebook Assistant, is reportedly leading the effort to build a new AI assistant.
