I sort of thought that for a moment too. But then I realised that this was HN so they're likely actually selling some kind of technology that I'm too uncool to know about. So they're talking about "Pencil" and "Paper" not pencil and paper as I understand it. Of course with their super cool, new age design website, actually finding out what they're talking about requires watching a video or something. Simply stating what something is and how it fits with pre-existing things is far too uncool.
