Obsidian as a Linux alternative to Microsoft OneNote
Updated
Our verdict
Obsidian can replace Microsoft OneNote for users who prioritize plain-text markdown notes, local storage, and knowledge linking over rich formatting and real-time collaboration. It excels at organizing interconnected ideas and works well offline, but lacks built-in audio recording, drawing tools, and native .one file support. The free version is fully functional, but cloud sync and collaboration require paid optional services. If you value simplicity, customization, and long-term data ownership over Microsoft’s feature-heavy, cloud-first workflow, Obsidian is a strong alternative—especially for technical users comfortable with markdown.

What is different
- Obsidian uses markdown and plain text; OneNote supports free-form rich text, audio, and inking
- Obsidian stores data locally by default; cloud sync requires optional paid service
- No built-in audio recording or handwriting support in Obsidian
- Obsidian lacks real-time collaboration; sharing requires external tools
- OneNote has native .one file support and export to .docx; Obsidian does not
Opening your Microsoft OneNote files
Obsidian cannot open Microsoft OneNote (.one) files directly. There is no built-in import or conversion tool for .one files. Users must manually extract content from OneNote using export to PDF or DOCX, then convert or import into markdown format. Third-party tools or scripts may help automate this, but results vary. Obsidian can export to PDF and supports markdown-based formats, but not .docx natively. For full compatibility, users need to rely on external conversion methods.
Switching from Microsoft OneNote to Obsidian, step by step
- Export OneNote content to PDF or DOCX by sections or pages
- Convert exported files to markdown using pandoc or online tools
- Create a new vault in Obsidian and import the converted markdown files
- Organize notes using folders, links, and tags to replicate notebook structure
- Enable sync via Obsidian's paid service or use a third-party cloud folder
