Overview
OneNote is Microsoft’s digital notebook, organised in the familiar paper metaphor of notebooks, sections and pages, with text, ink, images and files placed anywhere on an open canvas. Microsoft’s support documentation states that all supported versions of OneNote are free to download and use, and that certain premium features can be unlocked with an optional Microsoft 365 or Office subscription; signing in with a compatible subscription adds extras such as Ink Replay, Researcher and Math Assistant[4].
The app runs on Windows, Mac, the web, iPhone, iPad and Android, and each version reads the same cloud-connected notebooks[4]. That free cross-platform reach, combined with strong pen support on Windows tablets, explains its high position: for people already in the Microsoft ecosystem it costs nothing extra and stores notebooks in the account they already have.
OneNote’s history includes a long period with two Windows apps side by side. Microsoft’s guidance is that OneNote for Windows 10 reached end of support in October 2025 and that users should move to the OneNote desktop app[4]. The main limitations are the freeform canvas, which makes notes harder to export cleanly to Markdown or other tools, and the dependence on a Microsoft account and its cloud storage for sync. Users who need structured databases or plain-text files will find it less suited than Notion or Obsidian.
