Microsoft OneNote is a note-taking software developed by Microsoft. It is available as part of the Microsoft 365 suite and since 2014 has been free on all platforms outside the suite.[12] OneNote is designed for free-form information gathering and multi-user collaboration. It gathers users' notes, drawings, screen clippings, and audio commentaries. Notes can be shared with other OneNote users over the Internet or a network.
Key Information
OneNote is also available as a free, stand-alone app via the official website and the app stores of: Windows 10/11, MacOS, iOS, iPadOS and Android.[13] Microsoft also provides a web-based version of OneNote as part of OneDrive and Office for the web.
Overview
[edit]OneNote was announced by Microsoft's Bill Gates on November 17, 2002.[14] The software allows users to create notes that can include text, pictures, tables, and drawings. Unlike a word processor, OneNote features an almost 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 edits the file.
OneNote saves information in pages organized into sections within notebooks. Microsoft designed this user interface to resemble a tabbed ring binder, in 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 OneNote notebooks collect, organize, and share possibly unpublished materials—as compared to word processors and wikis, which often target publishing in some way. The difference shows in certain OneNote features and characteristics:
- Pages can be arbitrarily large
- There is no enforced uniform page layout or structure.
Users can move pages in 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, such as YouTube videos.[15] OneNote also integrates search features and indexing into a free-form graphics and audio repository. It can search pictures (e.g., screen captures, embedded document scans, photographs) for depictions of text. 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 and copy texts from pictures and documents using optical character-recognition.[16]
Its multi-user capability allows offline editing with later synchronization and merging. More than one person can work on the same page at the same time using OneNote as a shared whiteboard environment.
On March 17, 2014, Microsoft released the OneNote cloud service API, which allows third-party application developers to integrate the service into their apps. The API runs on Microsoft's globally available cloud and sends data from applications into the user's OneDrive. OneNote can render webpages as snapshot images.[13][17]
Microsoft also announced several new features in OneNote that use the service API:
- OneNote Clipper: A browser bookmarklet, which uses the OneNote service API and enables users to save a screenshot of a webpage to OneNote along with the URL. The text in the screenshot is searchable.[18]
- Email to OneNote: A feature enabling users to send emails to the address
me@onenote.comfrom specified email IDs to have the contents of the email saved to OneNote.[19]
File format
[edit].one file icons for sections (left) and notebooks (right)A OneNote notebook is stored as a folder with a separate data file for each section. OneNote files have a .one filename extension.[20] A .one file can be a OneNote notebook or a OneNote section.
Microsoft upgraded the file format twice after it had introduced OneNote 2003 — first in OneNote 2007, then in OneNote 2010.[21] OneNote 2003 files can be opened by both OneNote 2007 and OneNote 2010 in read-only mode and subsequently upgraded to the later versions of the file format.[22][23] OneNote 2010 can read and write OneNote 2007 file formats. It can also convert back and forth between the 2010 and the 2007 formats.[23]
Microsoft has documented the OneNote file format. It is an open format that can store varied multimedia content in a single .one file.[20][24][25]
Multiple .one files can be exported to a .onepkg file, which stores multiple .one files (corresponding to the individual notebooks) in cabinet file format.
Platform support
[edit]OneNote supports simultaneous editing of shared OneNote documents by multiple users when the document is stored in a shared folder in OneDrive. Dropbox was supported for some time as a sync protocol, but after Windows Live Mesh was discontinued, OneNote supported it for cloud-based storage and synchronization of OneNote files. OneNote clients, including the OneNote web app of Office Online, can view and edit them.
Microsoft made OneNote 2013 for Windows desktop available for free. OneNote for Windows and Mac are both based on a freemium model. Premium features such as SharePoint support, version history and Microsoft Outlook integration were previously available only to Office 365 and Office 2013 customers,[13][26] but on February 13, 2015, Microsoft removed all feature restrictions, except creation of local notebooks — the free edition only stores notebooks on OneDrive — from the programs, essentially making the program completely free to use.[27]
Windows
[edit]The first version, OneNote 2003, was only sold as a separate product for Windows[28] compatible with Windows XP and Windows 2000 as well as for Microsoft Tablet PCs with pen input.[29] Starting with Office 2007 it was then included as part of the Office suite, as the software was positioned more as a student tool rather than business.[30]
A Microsoft Store version of OneNote (formerly known as OneNote MX) was available for Windows 8 and RT, using OneDrive as a storage place. It is optimized for use on tablets by implementing a pie menu interface and invoking operating system's tablet-specific functionality.[31]
OneNote for Windows 10
[edit]In 2018, Microsoft announced that for OneNote on Windows, the Universal Windows Platform (UWP) based OneNote for Windows 10, now renamed "OneNote for Windows 10", would be the default experience for Office users on Windows. The Win32/Win64 "desktop" version would remain known as OneNote 2016 despite the release of Office 2019, would no longer receive new features, and would not be installed with Office by default, but remain available as an option.[32]
However, Microsoft reversed this decision in 2019; in the same year, the company announced that both versions would receive active development and the desktop version would once again be installed with Office by default.[33] The desktop application was renamed to simply OneNote,[34] matching the other programs in Office 365. OneNote is no longer installed with Windows starting from Windows 11, but is still available from Microsoft Store.[35]
In 2021, Microsoft announced that OneNote for Windows 10 would be discontinued and that they were working on migrating users and features to the desktop version. They also announced that it would be receiving some user interface changes to be more in line with Windows 11.[36]
Starting in April 2025, the OneNote for Windows 10 app began displaying a deprecation notice, encouraging users to transition to the desktop OneNote app. The UWP app officially reached its end of support in October 14, 2025, together with Windows 10.[37][38]
Mobile
[edit]OneNote is also available for cell phones. Microsoft currently has a stand-alone OneNote app for iOS[39] and Android.
OneNote Mobile for older Windows Mobile smartphones and pocket PCs was included with OneNote 2007.[40] It was released with Windows Phone 7 in 2010.[41] In 2011, OneNote Mobile went multi-platform as it was released for iPhone[42] followed by a version for Symbian as part of Microsoft Apps.[43] In 2012 Microsoft released OneNote for Android in a surprise move.[44]
On July 1, 2013, Microsoft released version 2 of its app for iPad, containing significantly updated features, to correspond more closely to those available on the Windows platform. On August 19, 2014, Microsoft updated OneNote for Android tablets to include handwriting support and touch-friendly navigation.[45] This version supports notebooks stored on OneDrive or SharePoint. In 2022, the Android version got a major refresh.[46]
Mac
[edit]On March 17, 2014, Microsoft released OneNote for Mac. It is compatible with OS X Mavericks and above and can be downloaded for free from the Mac App Store.[47]
The release of OneNote for Mac was part of Microsoft's broader strategy to make its Office suite more accessible across different platforms, and it marked the first time macOS users natively without third-party solutions.[37] This move was seen as a response to the increasing number of users who were working on multiple devices, including those running macOS. By offering OneNote for free, Microsoft aimed to attract new users and integrate their note-taking service into the broader ecosystem of Microsoft Office applications.
Version and licensing differences
[edit]The desktop OneNote and OneNote for Windows 10 have different functionality and user interfaces, which also differ from the versions for other platforms. Compared to OneNote for Windows 10, the desktop OneNote has a full Office ribbon interface, features the most customization options, runs on multiple versions of Windows, and provides the possibility of local notebook support as opposed to OneDrive cloud storage; it is the only version for any platform to offer the latter feature,[48] even as a paid option.
In addition to the version differences, OneNote features on Windows and Mac vary according to whether it is installed as a free or paid program. If a "compatible"[48] Office license (whether for the subscription Office 365 or the perpetual Office 2019) is present on the machine, the Windows desktop, Windows 10, and Mac versions all unlock additional functionality, which varies depending on the version: the desktop OneNote adds local notebook support, the Mac version adds stickers and OneNote for Windows 10 gains several features including stickers, ink replay, Researcher and Math Assistant. More premium features are in development for the Mac and Windows 10 versions.[34]
Reception
[edit]This section needs expansion with: Information about initial reception (OneNote 2003) and contemporary reception. You can help by adding to it. (December 2021) |
Christopher Dawson reviewed OneNote 2010, titling his favorable review "OneNote is Office 2010's killer app in education".[49] He speculated that the app would be particularly useful as a tool for student notetaking. In 2022 Microsoft has merged the OneNote and OneNote for Windows 10 apps into a single version, the older version OneNote for Windows 10 will continue to work but it will not get new updates, noting that "it will reach end-of-support in October 2025".[50] In 2023, Tom Warren of The Verge highlighted a new digital ink and pen feature addition gestures, and an AI-powered copilot feature to help you summarize pages or section of notes.[51]

View on GrokipediaHistory and development
Origins and early development
Microsoft OneNote was conceived in 2002 as an addition to Microsoft's Office suite, aimed at fulfilling the need for unstructured digital note-taking that traditional applications like Word could not adequately address.[10] The application drew inspiration from physical paper notebooks and digital binders, seeking to replicate their flexibility while overcoming limitations such as lack of searchability and organization in analog formats.[10] Bill Gates announced the project, codenamed Scribbler, on November 17, 2002, at the COMDEX trade show, highlighting its potential to capture ideas in a freeform manner for information workers.[3] Initial development was led by a team at Microsoft, emphasizing a freeform canvas that supported diverse input types including typed text, images, audio recordings, and digital ink.[10] This approach was particularly tailored for emerging hardware like Tablet PCs, allowing users to write notes by hand directly on the screen.[10] A key innovation during early betas was the introduction of a hierarchical structure consisting of notebooks, sections, and pages, which provided an intuitive way to organize content akin to a physical binder system.[11] The first public preview came with the Office 2003 Beta 2 release in March 2003, distributed to over half a million testers, where OneNote was bundled as an experimental component.[12] The full version was released on November 19, 2003, as a standalone product accompanying the Microsoft Office 2003 suite.[13] Early adoption faced challenges, as users accustomed to structured tools like Word viewed OneNote's freeform style as less essential for everyday tasks.[14] In response, Microsoft pivoted marketing efforts to highlight digital inking capabilities, positioning OneNote as a companion for Tablet PCs to capitalize on the growing interest in mobile handwriting input.[14] Despite initial hurdles, this focus helped establish OneNote's niche in unstructured information capture during the mid-2000s.Release history and major updates
Microsoft OneNote was first released on November 19, 2003, as a standalone digital note-taking application designed primarily for tablet PCs with support for ink input.[13] In December 2011, Microsoft made OneNote available for free on the web and mobile devices, expanding access beyond paid Office licenses.[3] The 2007 version, integrated into Office 2007 and released on January 30, 2007, introduced significant improvements to ink-to-text conversion and handwriting recognition, enhancing usability for stylus-based input. OneNote 2010, bundled with Office 2010 and launched on June 15, 2010, added multi-touch support and linked notes functionality, allowing users to connect notes directly to specific cells in Excel or locations in Word documents.[3] With Office 2013, released on January 29, 2013, OneNote version 15.0 emphasized cloud synchronization via SkyDrive (later OneDrive), enabling seamless access across devices and introducing the ability to embed Office files directly into notebooks.[3] OneNote 2016, part of Office 2016 and available from September 22, 2015, brought real-time co-authoring capabilities, allowing multiple users to edit notebooks simultaneously with presence indicators. In the 2010s, Microsoft shifted toward standalone applications; OneNote for Windows 10, a Universal Windows Platform (UWP) app, was introduced in July 2014 as a preview and generally released with Windows 10 on July 29, 2015, focusing on touch-optimized interfaces and integration with Cortana. Support for this version ended on October 14, 2025, after which it became read-only with no further security updates or features.[15][16] Entering the 2020s, OneNote deepened its integration with Microsoft 365 starting in 2021, with the legacy OneNote 2016 becoming a standalone app while a unified "OneNote for Windows" app (available via the Microsoft Store) emerged in 2022, combining features from the desktop and UWP versions and receiving monthly updates.[4] Version numbering evolved from Office suite alignment—such as 11.0 for 2003, 12.0 for 2007, 14.0 for 2010 (skipping 13 to avoid superstition), 15.0 for 2013, and 16.0 for 2016—to app-specific builds in the Microsoft 365 era, now using a YYMM format like Version 2509 (September 2025 build 19231.20156) for ongoing Current Channel releases.[17][18]| Version | Release Date | Key Updates |
|---|---|---|
| OneNote 2003 (v11.0) | November 19, 2003 | Initial release with ink support for tablets.[13] |
| OneNote 2007 (v12.0) | January 30, 2007 | Enhanced ink recognition and audio recording. |
| OneNote 2010 (v14.0) | June 15, 2010 | Multi-touch and linked notes to Office apps. |
| OneNote 2013 (v15.0) | January 29, 2013 | OneDrive sync and embedded files. |
| OneNote 2016 (v16.0) | September 22, 2015 | Real-time co-authoring. |
| OneNote for Windows 10 (UWP) | July 29, 2015 | Touch-optimized, Cortana integration; end of support October 14, 2025.[15] |
| OneNote for Windows (Microsoft Store) | 2022 (ongoing) | Unified app with monthly YYMM builds, e.g., Version 2509 (September 2025).[17] |
Core features and functionality
Note-taking and organization tools
OneNote provides a flexible freeform canvas on each page, allowing users to place content anywhere without rigid constraints, as pages feature an infinite size that expands as needed. This design supports drag-and-drop placement of text boxes, images, drawings, and handwritten ink, enabling intuitive arrangement of notes in a non-linear fashion.[19][7] The application structures notes through a hierarchical system where notebooks serve as the top-level containers, each holding multiple tabbed sections that group related content. Sections, in turn, contain pages and subpages for detailed note-taking, with support for predefined templates such as planners or meeting notes to standardize layouts, and a Quick Notes feature for capturing fleeting ideas that can later be moved into the main hierarchy.[20][21][22] Users can input content via keyboard typing directly on the canvas, stylus or pen for natural handwriting and drawing with real-time ink-to-text conversion that transforms sketches into editable text while preserving the original ink. Audio recording is also integrated, allowing capture of lectures or meetings with automatic transcription that includes timestamps for easy navigation to specific moments in the playback.[7][23][24][25] For organization, sections and pages can be color-coded to visually distinguish topics, while section groups allow nesting of multiple sections under a single folder-like container to manage large notebooks efficiently. Tags provide annotation options, such as to-do items or importance flags, which create interactive checklists that can be summarized later; outline tools further support hierarchical lists with up to five collapsible levels for structuring complex information. Search functionality enables retrieval across this organized content, including text, ink, and audio transcripts.[26][27][19][28][5][29] In 2025, enhancements include the ability to merge adjacent table cells for improved data structuring, accessible via right-click or the Table tab, and a paste text-only shortcut (Ctrl+Shift+V) that strips formatting to maintain clean note appearance.[30][31]Search, tagging, and multimedia support
OneNote provides robust search functionality that enables users to locate content across entire notebooks, including typed text, handwritten notes, and even spoken words within audio and video recordings. The search tool supports full-text queries, scanning pages, sections, and notebooks simultaneously, with results displayed in a navigable list that highlights matches for quick review. As of 2025, enhancements include contextual results powered by AI integration via Copilot, which prioritizes relevant matches based on note context and user history.[29][32][33] Optical character recognition (OCR) in OneNote allows extraction and searching of text embedded in images, PDFs, and scanned documents, a feature introduced with OneNote 2007 to convert visual content into searchable, editable text. Users can right-click an inserted image or printout to copy recognized text directly, facilitating annotation or integration into notes. Recent AI advancements, particularly from 2023 onward, have improved accuracy for handwritten text recognition through tools like Ink to Text, enabling better conversion of inked content in images to machine-readable format without manual intervention.[34][35][36] The tagging system in OneNote supports customizable tags for annotating and prioritizing notes, such as standard options like "To Do" or user-defined labels for tasks like "Follow up." Tags can be applied to specific text, paragraphs, or entire lines via the Home tab, with dynamic features allowing checkboxes for to-do items. The Find Tags tool opens a Tags Summary pane listing all instances of a selected tag across the notebook, enabling users to review, filter (e.g., unchecked items only), and navigate directly to associated pages for efficient organization. Custom tags are created through the Tags dropdown and persist within the notebook, though they may require reopening the file for full visibility in summaries.[37][38][39] Multimedia support in OneNote allows direct embedding of photos, videos, and audio clips into pages, enhancing notes with rich media. Users can insert files from local storage or record live content using built-in tools: audio via microphone for voice notes, video through webcam for quick captures, or screen recordings for demonstrations. These elements integrate seamlessly, with playback controls embedded on the page, and search extends to transcribed audio/video content for spoken word queries. Attached files appear as icons on the page and can be saved to the local computer by right-clicking the icon and selecting Save As to choose a destination folder. For mathematical content, OneNote supports ink-based equation input convertible to typed format via the Draw tab's Math Assistant, or entry through the Equation tool for structured formulas, approximating LaTeX-style notation in professional or educational contexts.[24][40][41][42][43] Drawing and annotation tools in OneNote facilitate freehand sketching and precise markup, accessible via the Draw tab with support for stylus, mouse, or touch input. Shape recognition automatically refines imperfect drawings into clean geometric forms, such as circles or rectangles, while the ruler tool—available on touch-enabled Windows devices—enables straight lines at any angle for diagrams or measurements. Highlighters and pens allow annotation over any content type, including text, images, or embedded media, with color and thickness options to emphasize key elements without altering originals.[44][45]Collaboration and integration capabilities
Microsoft OneNote enables real-time co-authoring, allowing multiple users to edit the same notebook simultaneously while seeing presence indicators that highlight where others are making changes.[46] This feature, first introduced in 2013 for web applications, was extended to desktop versions in 2015 with Office 2016.[47] Notebooks can be shared via secure links or email invitations, supporting both view-only and edit permissions.[48] Integration with Microsoft 365 enhances collaborative workflows by allowing users to embed Outlook tasks directly into notes, where selected text becomes actionable items synced across applications.[49] For Teams meetings, OneNote notebooks can be added as tabs in channels for shared note-taking, and meeting details such as agendas and attendees can be inserted automatically.[50] PowerPoint slides can be embedded as printouts, enabling annotations over presentation content during reviews.[51] Since 2024, Loop components provide dynamic, real-time editable elements like tables and lists that update across OneNote, Teams, and Outlook.[52] OneNote supports third-party integrations through export options to PDF for static sharing or to Word for further editing.[53][54] Files from OneDrive and SharePoint can be embedded directly, as notebooks are natively stored in these services for seamless access.[55] Developers can extend functionality using the Microsoft Graph API, which provides programmatic access to create, read, and update notebooks, sections, and pages.[9] In 2024, OneNote introduced a refreshed meeting details pane that allows users to pull Teams transcripts and related content directly into notes with one click.[56] Additionally, AI-powered suggestions via Copilot enable collaborative summaries of notes, highlighting key points and action items for team review.[57] Security features in OneNote include password protection applied to individual sections, locking content after a period of inactivity to prevent unauthorized access.[58] Version history tracks changes through recent edits and page versions, allowing users to view or restore previous states in OneNote for the web or desktop.[59] In enterprise editions, administrators can enforce sharing policies and access controls via the Microsoft 365 admin center to manage external collaboration and data protection.Technical specifications
File format and data structure
Microsoft OneNote employs a proprietary binary file format for storing notes, documented in the open specification [MS-ONE], which serves as a persistence mechanism for hierarchical collections of notebooks, sections, and pages.[60] A notebook is represented as a directory containing multiple .one files, where each .one file corresponds to a single section and encapsulates the data for its constituent pages in a binary container.[61] This format supports revision history through layered data structures, allowing incremental updates without overwriting prior versions.[61] The internal structure relies on a combination of binary streams and XML fragments to define content organization. Key elements include the Notebook (NNBK) structure for overall hierarchy, Section (NSP) for grouping pages, and Page (NP) for individual notes, all defined via a schema that outlines properties like object identifiers, timestamps, and content nodes.[62] Text, outlines, and metadata are encoded in XML, while multimedia such as images, audio, and embedded files is stored as binary data streams within the .one file, enabling rich media integration without external dependencies.[63] The format maintains backward compatibility with earlier versions of OneNote through versioned object nodes and extensible properties in the [MS-ONE] specification, ensuring legacy .one files can be opened in newer applications.[60] Users can export content to standard formats like .docx or .pdf directly from the application, facilitating interoperability with other tools.[53] Although the specification is publicly available, there is no native open-source editor for .one files; however, third-party tools leveraging the [MS-ONE] documentation enable partial parsing and processing.[64] During the 2010s, OneNote evolved toward cloud-native storage, with version 2013 gaining seamless integration with OneDrive and free access starting in 2014, though support for local .one files persisted for offline use.[65] In desktop applications, notebooks are subject to practical size limits of approximately 2 GB to maintain performance, and .one files cannot be directly edited outside of OneNote without specialized parsing.[66] As of 2025, updates to the Windows app include temporary adjustments for handling large attachments, capping downloads at 100 MB to optimize synchronization.[43]Synchronization and storage options
Microsoft OneNote primarily synchronizes notebooks through integration with OneDrive, Microsoft's cloud storage service, which serves as the default sync mechanism for users signed in with a Microsoft account. This integration enables real-time updates across devices, allowing users to access and edit notes offline with changes automatically syncing upon reconnection to the internet. Users can access the Notebook Sync Status dialog to disable automatic syncing and switch to manual mode, which queues changes for later synchronization and can help reduce typing lag during input.[67][68] OneNote employs a dedicated synchronization engine that merges concurrent edits from multiple users or devices, minimizing conflicts by intelligently combining changes; in cases where resolution is needed, users can compare and manually accept or reject conflicting versions on affected pages.[69] Storage options in OneNote are tied to OneDrive quotas, with free personal accounts providing 5 GB of shared cloud storage across Microsoft services, including OneNote notebooks. Microsoft 365 subscribers receive 1 TB of OneDrive storage per user, supporting extensive notebook collections with multimedia content. For enterprise environments, OneNote leverages OneDrive for Business or SharePoint, where the default allocation is 1 TB per user, configurable up to 5 TB depending on the organization's licensing and licensed user count.[70][71] Users can opt for local storage of non-synced notebooks directly on their device, particularly in the desktop versions of OneNote, avoiding cloud dependency for sensitive or offline-only content. These local notebooks reside in user-specified folders, such as the Documents directory, and do not automatically sync unless manually moved to OneDrive. OneNote provides an optimization tool to reduce the size of local notebook files by clearing unnecessary cached data. This feature can be accessed via File > Options > Save & Backup > Optimize All Files Now, which helps improve performance and resolve synchronization issues. In some versions, such as the Windows 10 app, it may be accessed through the Settings gear icon.[72] Backups for local notebooks are managed through export functions, allowing users to save sections or entire notebooks as .onepkg files, or via automatic weekly backups configurable in the app's settings. For cloud-synced notebooks, version history is preserved through OneDrive's mechanisms, enabling restoration of pages or sections to previous states, with automatic backups retaining up to 30 days of changes for personal accounts.[73][55][74] Following the end-of-support for OneNote for Windows 10 on October 14, 2025, Microsoft recommends transitioning to the new OneNote app for Windows for continued editing and updates.[75] Regarding privacy and recovery, OneNote secures data in transit using TLS encryption to protect synchronization between devices and OneDrive servers. For cloud-stored notebooks, recovery of accidentally deleted items is possible from OneDrive's recycle bin, which retains files for up to 30 days in personal accounts before permanent deletion. Local files lack built-in on-device encryption, relying on user-applied section passwords (using 128-bit AES) for protection, while cloud notebooks benefit from OneDrive's at-rest encryption.[76][58][77]Platform support
Desktop versions
The desktop versions of Microsoft OneNote provide robust note-taking capabilities tailored for Windows and macOS environments, emphasizing advanced input methods, extensibility, and integration with productivity workflows.[4] On Windows, the legacy OneNote 2016, now referred to as the OneNote desktop app, is available as a perpetual license component of Office 2019, Office 2021, and Office LTSC 2024, offering full feature parity including support for local notebooks and advanced formatting tools.[78] It also supports a variety of command-line switches specific to this version, allowing customized startup behaviors such as opening specific .one files, creating new sections, importing XML data from older OneNote formats, pasting clipboard contents, launching in Quick Notes sidenote mode, starting immediate audio or video recording, opening pages via hyperlinks, running in safe mode, and printing files.[79] This version installs by default with Microsoft 365 subscriptions alongside other Office applications and supports standalone use on any PC.[78] In contrast, the new OneNote for Windows, distributed via the Microsoft Store since 2022, serves as the modern successor with ongoing updates, including enhancements to ink functionality such as a redesigned Draw tab, reduced ink latency by up to 85%, and improved handwriting straightening for better legibility.[4][80][81] The Windows 10 UWP version of OneNote reached end of support on October 14, 2025, transitioning to read-only mode thereafter, with downloads available through the fall of that year.[75] For macOS, OneNote has been available as a native application since its initial release on March 17, 2014, compatible with OS X Mavericks and later versions, evolving through version 16 and beyond to include full synchronization with OneDrive-stored notebooks.[82][4] The app supports trackpad gestures for drawing and navigation, enabling users to sketch with one finger or pan the canvas with two fingers directly on the trackpad.[83] In 2025, updates introduced features like a "Paste Text Only" option (via Cmd+Shift+V shortcut) to strip formatting during insertion and the ability to merge adjacent table cells for enhanced organization.[30][31] Across both Windows and macOS desktop implementations, OneNote shares core traits such as extensive keyboard shortcuts for efficient navigation and editing—for instance, Ctrl+N to create a new page or Alt+N for inserting files—and the Print to OneNote virtual printer driver, which captures content from any application as embedded printouts in notebooks.[84][85] Official add-ins, such as the Class Notebook add-in for educational distribution and review, are supported to extend functionality without third-party dependencies.[86] Performance characteristics include scalable resource consumption tied to notebook complexity, with options to disable hardware graphics acceleration if issues arise, and built-in hardware acceleration for smooth ink rendering on compatible devices.[87] These desktop apps also enable seamless synchronization of changes across platforms via Microsoft 365 accounts.[4]Mobile and web versions
Microsoft OneNote offers dedicated applications for iOS and Android devices, enabling users to capture and manage notes on the go with a touch-optimized interface designed for mobile screens. The iOS version was first released in 2011, providing early support for iPhone and iPad users to create notebooks, add text, and synchronize content across devices.[88] The Android app followed in February 2012, initially supporting devices running Android 2.3 or higher, and has since evolved to include features like quick note creation via home screen widgets for instant capture without opening the full app.[89][90] Both platforms integrate camera functionality through Microsoft Lens for scanning documents and extracting text, allowing users to insert photos or PDFs directly into notes as images or searchable content.[91] Voice-to-text dictation is also supported, enabling hands-free note-taking by converting spoken words into editable text in multiple languages.[7][92] Push notifications alert users to changes in shared notes, such as edits or comments from collaborators, ensuring timely awareness without constant app monitoring.[93] Notes are stored locally in the app's cache for quick access and automatically synchronize with OneDrive, providing seamless backup and cross-device availability once connectivity is restored.[94] However, mobile versions face limitations, including reduced precision for inking and drawing on smaller screens compared to larger devices, and the absence of add-ins or extensions available in desktop editions.[95] The web version of OneNote, accessible via OneNote.com since 2011, utilizes HTML5 for browser-based note-taking and supports major browsers including Chrome, Edge, and Safari.[88] It allows full editing capabilities such as inserting text, images, and tags, with automatic saving to OneDrive for cloud storage and sharing.[96] Offline access is limited, requiring an internet connection for most editing and syncing functions, though read-only viewing of cached pages is possible in some scenarios.[97] Education-specific features, like Class Notebooks, are prominently supported, enabling teachers to distribute content libraries, assignments, and collaborative sections to students directly in the browser.[98][99] Limitations include the inability to embed certain desktop-specific media types, such as advanced audio or video integrations, and no support for custom add-ins.[97]Versions, licensing, and availability
Differences across versions
OneNote 2016, the legacy desktop version included with Office 2016 and later renamed simply as OneNote, emphasizes full local storage capabilities, enabling offline editing and management of notebooks without mandatory cloud synchronization, along with support for add-ins and macros.[4] However, it receives no security updates or feature enhancements after October 14, 2025, limiting its long-term viability for users requiring ongoing improvements.[4] OneNote 2016 also supports command-line switches for advanced customization of startup and operations. These switches are applied to the ONENOTE.EXE executable (typically located at C:\Program Files\Microsoft Office\root\Office16\ONENOTE.EXE) via shortcuts or the Run dialog, by appending them after the executable path (e.g., "C:...\ONENOTE.EXE" /sidenote). They are specific to the OneNote 2016 desktop version and do not apply to newer versions such as OneNote for Microsoft 365.[100] Key switches include:- "filename" — Opens a specific .one file.
- /new — Creates a new section in the current notebook.
- /import "filename" — Imports XML data from OneNote 2003/2007 formats.
