Microsoft OneNote is Microsoft's free form digital notebook, with sections, pages, handwriting and Microsoft 365 integration, the natural note-taking app for those in the Microsoft ecosystem. It organises notes into notebooks, sections and pages like a physical binder, and lets you type anywhere on the page, draw and handwrite (great with a stylus), insert images, files and audio, and sync across devices, integrated with Microsoft 365 (Outlook, Teams, OneDrive). Free to use and included across Microsoft platforms, OneNote is a flexible, free form note-taking app especially suited to those in the Microsoft ecosystem, students, and anyone who likes handwriting and free form notes. For the Microsoft ecosystem, OneNote is a leading note-taking choice.
OneNote's distinction is free form, notebook style notes, free and in the Microsoft ecosystem. Its free form canvas lets you place text, drawings and handwriting anywhere like a real notebook, which suits handwriting and visual note takers, and it is free and integrated with Microsoft 365 and OneDrive, so Microsoft users and students get it at no cost within their stack, which many tools do not offer for free. That free form style, free price and Microsoft integration set it apart.
Microsoft OneNote is best for people in the Microsoft ecosystem, students, and anyone who likes free form, notebook style notes with handwriting and drawing, wanting a free, flexible note app integrated with Microsoft 365. It suits Microsoft users and handwriting note takers. It is a weaker fit for those wanting a flexible database workspace, where Notion fits, a local, linked knowledge base, where Obsidian fits, classic structured notes and clipping, where Evernote fits, or team wikis, where Confluence fits.
The core strengths are notebooks, sections and pages, a free form canvas where you type, draw or handwrite anywhere, inserting images, files and audio, handwriting and stylus support, cross device sync, and Microsoft 365 integration (Outlook, Teams, OneDrive). OneNote offers free, flexible, free form notes. Its free form style, free price and Microsoft integration are its defining advantages.
Microsoft OneNote is free to use across Windows, Mac, web and mobile, and is included in Microsoft 365 plans (with more OneDrive storage).

Microsoft OneNote integrates with Microsoft 365 (Outlook for meeting notes, Teams, Word, OneDrive) and other apps.

Free form, free, Microsoft integrated notes are the signature strength: OneNote's canvas lets you place text, drawings and handwriting anywhere like a real notebook, it is free, and it integrates with Microsoft 365 and OneDrive, so Microsoft users and students get flexible notes at no cost within their stack. For them, this is the main reason to use OneNote.
Microsoft OneNote is well rated for being free, free form, good for handwriting, and integrated with Microsoft 365, with Microsoft support, though its free form flexibility can feel less structured than some note apps. Its G2 reviews praise the free price, free form canvas and Microsoft integration, with organisation and structure the main considerations.
For people in the Microsoft ecosystem, students and anyone who likes free form, handwriting friendly notes, OneNote is an excellent, free choice. The main caution is that its free form style is less structured than some tools, so those wanting a flexible database workspace may prefer Notion, local control Obsidian, structured clipping Evernote, and team wikis Confluence, but for free form notes in the Microsoft ecosystem OneNote leads.
