Facebook's AI assistant is ready to hang out in Messenger

A couple of years ago, Facebook introduced M, an AI-powered personal assistant for Messenger. The idea behind M is that you could ask it to do pretty much anything -- book flights, cancel your cable service and even find a plumber -- and it'll do it for you, with the occasional help from human beings. It was rolled out to just a small test market of users in San Francisco, but we've not heard much about it since then. Today, Facebook has announced that a version of M will finally be available to all Messenger users in the US. It's called "M suggestions," and it'll essentially pop up at certain points of your Messenger conversation to recommend related content or features.
