The OneNote alternative that keeps your notes as files

OneNote is capable, but heavy: notebooks stored in a proprietary format on OneDrive, sync conflicts, and no clean way to get years of notes out. Obsidian keeps the notebook-and-section structure you are used to, as plain folders of Markdown files that open instantly and work offline. The free Notebook Navigator plugin gives you a familiar two-pane view of it all: structure on the left, pages with previews on the right.

Why people move on from OneNote

  • Your notes are hard to get out. OneNote's format is proprietary, and export options are limited and lossy.
  • Sync conflicts and slow loading plague large notebooks.
  • No Markdown. Content is locked to OneNote's editor and does not travel well to other tools.
  • The interface has grown heavy compared to fast, local-first note apps.

Obsidian is the opposite: local Markdown files, instant startup and search, full offline support, and an ecosystem of thousands of plugins, while Notebook Navigator preserves the notebook-style browsing that made OneNote feel organized.

How to move from OneNote to Obsidian

The official, free Obsidian Importer connects straight to your Microsoft account, so there is no manual export dance.

1. Install Obsidian and create a vault

Download Obsidian for free from obsidian.md and create a vault, a folder where your Markdown files will live.

2. Import your notebooks

In Obsidian, go to Settings → Community plugins, install Importer, run Importer: Open importer, and choose Microsoft OneNote. Sign in with your Microsoft account, pick the notebooks to import, and pages are converted to Markdown with images and attachments copied into your vault.

3. Install Notebook Navigator

Install Notebook Navigator from Community plugins (or with one click from this install link) to browse your imported notebooks in a familiar two-pane view.

A familiar structure, a faster home

  • Notebooks and sections → folder tree. Your hierarchy carries over as folders, browsable in the left pane.
  • Page lists → visual previews. Unlike OneNote's bare page titles, every note shows a preview and thumbnail.
  • Colored notebooks → colors and icons. Give each folder its own color and icon, just like OneNote's colored notebook covers.
  • Tags and properties add dimensions OneNote never had.

And your notes are just files: back them up, grep them, version them with git, or open them in any editor. No lock-in, ever.
