Microsoft OneNote is a desktop program for note taking and multi-user collaboration. It is fitted with a tiered organizational system consisting of notebooks, sections, and notes. Each page appears to be a blank canvas where you can highlight, draw, and type contents, making it a suitable tool for both quick note taking and storing extensive research papers. You can also supplement your notes with screen clippings and audio commentaries. Your compilation of OneNote documents can be shared across multiple devices; it can be viewed on both desktop and smartphones by you or by several users.
