M (virtual assistant)


M was a virtual assistant by Facebook, first announced in August 2015, that can automatically complete tasks for users, such as purchase items, arrange gift deliveries, reserve restaurant tables, and arrange travel. By April 2017, it was available to about 10,000 users. It works inside the Facebook Messenger instant messaging service.
When a user makes a request for M, it uses algorithms to determine what the user wants. If M doesn't understand, a human takes over the conversation, unbeknownst to the user. This allows M to learn.
Alex Lebrun runs the project, which began in 2015, and which in April 2017 the MIT Technology Review called "successful".
In January 2018, Facebook announced that they would be discontinuing M. The company stated that what they learned from M would be applied to other artificial intelligence projects at Facebook.

Rollout of suggestions

In April 2017, Facebook enabled suggestions, powered by M, for users in the United States. M scans chats for keywords and then suggests relevant actions. For example, a user writing "You owe me $20" to a friend triggers M to enable the user's friend to pay the user via Facebook's payment platform.
