Microsoft OneNote is a note-taking software developed by Microsoft. It is available as part of the Microsoft Office suite and since 2014 has been free on all platforms outside the suite. OneNote is designed for free-form information gathering and multi-user collaboration. It gathers users' notes, drawings, screen clippings, and audio commentaries, and notes can also be shared with other OneNote users over the Internet or a network. OneNote is also available as a free, stand-alone app via the official website and the app stores of: Windows 10, MacOS, iOS, iPadOS and Android. Microsoft also provides a web-based version of OneNote as part of OneDrive and Office for the web. Overview OneNote was announced by Microsoft's Bill Gates on November 17, 2002. The software allows users to create notes that can include: texts, pictures, tables, and drawings. Unlike a word processor, OneNote features a virtually unbounded document window, in which users can click anywhere on the canvas to create a new text box at that location. OneNote saves data automatically as the user makes edits to their file. OneNote saves information in pages organized into sections within notebooks. Microsoft designed this user interface to resemble a tabbed ring binder, into which the user can directly make notes and gather material from other applications. OneNote notebooks collect, organize and share possibly unpublished materials – as compared to word processors and wikis, which usually target publishing in some way. The difference shows in certain OneNote features and characteristics: Pages can be arbitrarily large Images can be inserted There is no enforced uniform page layout or structure. Users can move pages within the binder and annotate them with a stylus or word-processing or drawing tools. Users may add embedded multimedia recordings and hyperlinks. They can also add embeddable content like YouTube videos. OneNote also integrates search features and indexing into a free-form graphics and audio repository. It can search for images (e.g. screen captures, embedded document scans, photographs) for embedded text content. It also searches "electronic ink" annotations as text and phonetically searches audio recordings on a text key. It can replay audio concurrently with notes taken during the recording. It can also extract or copy texts from images and documents using Optical Character Recognition Its multi-user capability allows offline paragraph-level editing with later synchronization and merging. This allows collaboration among multiple individuals in a notebook when they are offline. More than one person
