What Obsidian is
Obsidian is a note-taking application that operates directly on a folder of Markdown files — a “vault” — on your own disk. Notes link to each other with [[wiki-style]] brackets, and the app builds a navigable graph of those connections. Everything beyond the basics comes from a large community plugin ecosystem.
The architectural fact that everything else follows from: there is no database and no proprietary format. Your notes are .md files in an ordinary folder, readable in any text editor, greppable from a terminal, and versionable in Git. If Obsidian disappeared tomorrow you would lose an interface and nothing else — which, for a body of notes you intend to keep across a career, is a materially different proposition from every hosted alternative. Local files also mean it works offline: on a plane, in a field station, on a machine with no network at all.
Why researchers use it
- Your notes are files — no export step, no lock-in, no format that stops being readable when a company changes strategy.
- Linking surfaces connections — the paper you read in year one turns out to bear on the chapter you write in year three, and the backlink is how you find out.
- Zotero integration — the Citations plugin pulls paper metadata directly into literature notes, so citing from your notes is a keystroke rather than a lookup.
- Dataview — query your vault like a database: every paper tagged
#to-read, every note mentioning a method, assembled automatically and kept current. - It works offline and syncs how you choose — Git, a cloud folder, or Obsidian’s own paid sync, and none of them are mandatory.
Where it fits in a research workflow
Obsidian is the thinking layer between reading and writing — where papers become ideas and ideas become arguments. It is not a reference manager and not a manuscript tool, and treating it as either produces frustration.
The pipeline that works: capture papers in Zotero, write literature notes in Obsidian with metadata pulled in by the Citations plugin, develop your own synthesis in permanent notes, and when a chapter takes shape, export the Markdown through Pandoc to PDF or Word — or move to Overleaf if the venue wants LaTeX. The complete PhD setup walks through the whole arrangement. It even presents: Advanced Slides turns a note into a deck without opening PowerPoint.
Getting started
An hour to a working vault, and resist the temptation to build a system first.
- Create a vault as an ordinary folder and start writing notes. Do not spend the first week configuring plugins and folder hierarchies — the structure that works emerges from the notes, and the one you design in advance never survives contact with them.
- Install three plugins and no more: Citations for Zotero, Dataview for querying, Templater for note templates. Add others only when you hit a specific problem you can name.
- Write one literature note per paper you read, in your own words. This is the habit that makes the vault valuable; the software is incidental to it.
- The step people skip: put the vault in Git. Plain Markdown versions beautifully, you get a full history for free, and you get an off-machine backup — which is the actual disaster you are guarding against.
Obsidian vs the alternatives
| Alternative | Does it better | Pick it if |
|---|---|---|
| Logseq | Outliner-first structure, block references, daily journaling | You think in bullets rather than documents |
| Notion | Real-time collaboration and structured databases | The notes are shared lab infrastructure |
| Zettlr | Academic writing with citations and Pandoc export built in | You want to write papers, not maintain a vault |
| Zotero | Everything about managing the papers themselves | You need references, not notes about them |
Obsidian wins on ownership, longevity, and flexibility. It loses badly on collaboration, which is genuinely single-user territory.
Cost, licensing, and your data
Free for personal and academic use, including all core features and the entire community plugin ecosystem — the free tier is the product, not a trial. Paid add-ons are optional: an end-to-end encrypted sync service and a publishing service. A commercial licence applies to company use, which does not affect academic work.
Data governance is as clean as it gets: notes are files on your disk, nothing is uploaded unless you choose a sync method, and the vault can live on an encrypted volume or an institutional drive. That makes Obsidian appropriate for notes containing participant quotes or unpublished results in a way hosted note apps are not. The caution is plugins — they are community-written code with access to your entire vault, so install deliberately and prefer widely used ones. The same judgement you would apply to a browser extension applies here.
The honest review
Strengths. Ownership is the feature, and it compounds over a career. Plain Markdown means the notes you write during a PhD are still readable and searchable in twenty years regardless of what happened to the company — a claim no hosted competitor can make. The linking model genuinely does surface connections you would otherwise lose, and combined with Zotero and Dataview it becomes a research system rather than a note app.
Limitations. Collaboration is effectively absent. A shared folder is not co-editing, and any workflow needing two people in one note at once is the wrong workflow for this tool. The plugin ecosystem is both its greatest strength and a real fragility — plugins break on updates, get abandoned, and occasionally conflict, so a vault depending on five community plugins carries five maintenance risks. It invites procrastination through configuration: an entire subculture exists around building note systems instead of writing. And mobile editing, while functional, is not pleasant.
Verdict. Adopt it if you read a lot and want the notes to still be there in ten years. Skip it if your notes need to be shared and co-edited, or if you suspect you will spend more time configuring it than writing in it. The condition that flips the answer is honesty about that second point — for some people the tool becomes the project.
Common questions
Is Obsidian free?
Yes, for personal and academic use — all core features and the full community plugin ecosystem, with no time limit. Optional paid services add encrypted sync and web publishing, and a commercial licence applies to company use.
Can I use Obsidian with Zotero?
Yes, and it is one of the strongest reasons to choose it. The Citations community plugin reads a .bib file exported from Zotero — kept current by Better BibTeX — and pulls paper metadata directly into your notes, so literature notes carry live citation data.
Is Obsidian good for collaborative note-taking?
No. It is designed for a single user on local files, and a shared cloud folder produces sync conflicts rather than collaboration. For shared lab notes, Notion is the appropriate tool.
