Serious question: Did you read the article, or did you just watch the video? Reading the article along with watching the video made it perfectly clear to me what this product is doing, despite the fluff in the video.
It appears to be sorting and arranging various bits of data. The examples shown include messages, and a flight reservation. What all kinds of data bits DO integrate? Does this read my email (or replace it)? Does this read (or replace) the news feeds of my social networking accounts? Where did it get that flight itinerary? Why is everyone in this video talking a selfie every two seconds, is Inbox sharing or managing photos for you?
I think this supposed to be an improved version of Google Keep, perhaps with some hooks into Gmail and your phone's camera. But all I have to go by is a few paragraph of fluff, and a 60-second video of young people staring down at their phones. Feel free to fill in the blanks, if you picked up some more solid information that we're missing.
