About
Overview
Obsidian is a local-first, Markdown-based note-taking application. Unlike cloud-based tools, your notes are stored as plain text files on your own device. Its powerful bi-directional linking system turns your notes into a connected knowledge graph.
Pricing & Free Tier
Free Tier: Yes. Free for personal use, with all core features unlocked.
Commercial License: $50/user/year. Required if you use it for work.
Sync: $4/month (billed annually). End-to-end encrypted sync across devices.
Publish: $8/month to publish notes as a website.
How to Use
- Download Obsidian for your OS.
- Create a "Vault" (a folder where notes are stored).
- Create a new note and use
[[Note Name]]to link to other notes. - Open the "Graph View" to visualize connections between ideas.
Important Notes
- Sync Costs: While the app is free, syncing across devices is a paid service. You can use free alternatives like iCloud, Dropbox, or Git.
- Mobile Limitations: The iOS and Android apps are functional but can be slow with extremely large vaults (10,000+ notes).
