Obsidian
Obsidian is a markdown-based knowledge app with bidirectional links and full data ownership. Learn why researchers use it and when to use alternatives.
Why this tool?
The problem
Notes scattered across cloud apps create vendor dependency—when the tool changes or shuts down, your knowledge base disappears with it.
The old way
Use Notion or Evernote and eventually migrate everything when pricing changes, the product pivots, or you want to export your data.
The better way
Obsidian stores everything as plain markdown files in a folder you own. Your knowledge base is portable, permanent, and readable without any app.
What makes it stand out
Bidirectional links and the graph view surface unexpected connections between notes. The plugin ecosystem means Obsidian becomes whatever you need it to be.
Tradeoffs to consider
No built-in real-time collaboration; sync requires a paid add-on or self-setup with iCloud/Dropbox; steeper learning curve than simpler note apps.
Who it is for
When not to use it
If you need real-time team collaboration, a simple UI for non-technical users, or cloud-first sync out of the box without a paid add-on.
