Looking for an Obsidian alternative? Meet MDX.
Obsidian is a brilliant tool for building a vault of linked notes — and it's free. But if you came here because you really just want to write a document, format it visually, and export a clean Word or PDF, Obsidian's graph, plugins and LaTeX can be more than you need. MDX focuses on one document at a time, with visual math, citations and export built in — and it opens the same plain .md files.

When Obsidian is the better choice: Obsidian is one of the best tools in existence for building a personal knowledge base — it's free for any use (including work), runs on mobile, and its backlinks, graph view and plugin ecosystem are unmatched. If you want a connected second brain, keep Obsidian. MDX is for a narrower job: when you mainly need to write a document, format it without fuss, and export a clean Word or PDF file — with visual math and citations built in rather than assembled from plugins.
Why people switch to MDX
A document editor, not a vault
Obsidian is built around a vault of interlinked notes — backlinks, graph view, daily notes. MDX is built around one document at a time: open it, format it visually, export it. If you don't need a knowledge graph and just want to write and hand something off, MDX has far less to set up.
Math & citations without assembling plugins
In Obsidian, math means typing LaTeX source, and citations and Word export mean installing community plugins plus Pandoc. MDX edits equations visually (MathLive), imports .bib/.ris/CSL citations, and exports .docx — all built in, nothing to wire together.
Open your vault's files directly
MDX opens the same plain .md files in your Obsidian vault. Your text, headings, tables, code and math come across cleanly. Obsidian-specific syntax like [[wikilinks]] and Dataview queries won't render as live features — MDX reads standard Markdown, not a vault.
MDX vs Obsidian — questions
Is MDX a good Obsidian alternative?
It depends on what you use Obsidian for. If you want a linked vault with backlinks, graph view and plugins, Obsidian is the better tool and it's free. If you mostly write standalone documents and want visual math, built-in citations, and Word export without installing plugins or Pandoc, MDX is the simpler fit. Both store plain .md files locally.
Is Obsidian free? Why would I pay for MDX?
Obsidian is free for all uses, including commercial work; paid Catalyst, Commercial, Sync and Publish are optional. MDX is a $15 one-time purchase. You're paying for built-in visual math, citation management and Word/PDF export that in Obsidian require assembling community plugins plus Pandoc.
Can I open my Obsidian vault in MDX?
MDX opens the individual .md files in your vault as documents — text, headings, tables, code and math render cleanly. It does not read a vault as a graph: Obsidian-specific features like [[wikilinks]] and Dataview won't be interactive. MDX edits one document at a time rather than a connected vault.
Does Obsidian have mobile apps and MDX doesn't?
Correct. Obsidian has iOS and Android apps; MDX is desktop-only (macOS, Windows, Linux). If editing on your phone or tablet matters, that's a genuine reason to stay with Obsidian.
Does MDX export to Word like Obsidian?
MDX exports DOCX, PDF and HTML built in. In Obsidian, PDF export is built in, but Word (.docx) export requires a community plugin plus a separate Pandoc install.
