The best Notion alternative for personal notes and knowledge: fast, offline by design and stored as plain files, but built for one person more than for a team.
What it is
Obsidian is a note-taking app that keeps every note as a Markdown file in a folder on your own device, so it works fully offline and your notes stay readable without the app. Links, backlinks and a graph view connect ideas, and thousands of community plugins add calendars, tasks and more. The Bases core plugin (since version 1.9 in 2025) adds Notion-style table, card, list, Kanban and map views over note properties, still stored in your files. The app is free for personal and work use; paid add-ons are Sync at $4 a month billed yearly or $5 monthly per user (end-to-end encrypted, version history, shared vaults) and Publish at $8 a month billed yearly or $10 monthly per site. An optional Commercial license is $50 per user a year and a one-time Catalyst supporter license is $25. Windows, macOS, Linux, iOS and Android. Checked November 12, 2026.
Best for
- Personal notes and knowledge bases
- Writers and researchers who link ideas
- People who want offline, local files
What we like
- Works fully offline; notes are plain Markdown files you own
- Free for personal and work use
- Huge plugin ecosystem and Bases database views
What to watch
- No real-time co-editing; weak for team wikis
- Syncing between devices costs $4 to $5 a month unless you set up your own sync
- Notion pages and databases do not import one to one; layouts and relations need rework
- Plugins vary in quality and setup takes time
