Obsitex turns an Obsidian vault into a professional LaTeX/PDF document. You write in plain Markdown — the way you already take notes — and Obsitex assembles your notes into one .tex file you can compile with Overleaf, GitHub Actions, or any LaTeX installation.

What Obsitex is

Obsitex is a web app. It reads the Markdown files of an Obsidian vault — by default straight from your local drive, or from OneDrive if you prefer the cloud — converts them to LaTeX, and hands you the result, ready to compile into a PDF.

If you have used OneLatex before: Obsitex is its sibling. The idea is the same — write your content in a familiar tool, get LaTeX out — but the source is an Obsidian vault of Markdown files instead of a OneNote notebook. Because Markdown is different from OneNote, some things are written differently. This guide covers the Obsitex way.

How it works, in three steps

1. Load from your vault. You pick a project folder in your vault and, inside it, the manuscript you want to convert. Obsitex reads its Markdown files in a defined order.
2. Convert to LaTeX. Obsitex turns headings, lists, tables, images, citations and everything else into LaTeX and merges them into a single document.
3. Create your document. Export the result to Overleaf, GitHub, OneDrive, or download it to your browser, then compile it into a PDF.

What makes Obsitex different

• Your content stays with you. The default converter runs entirely in your browser — your notes are never sent to our servers.
• You control the order. The order of your document follows the order you set in Obsidian (via the Flexplorer plugin), or simple number prefixes on file names.
• The preamble is yours. Obsitex never silently injects LaTeX packages. What goes into the preamble is defined by a template you control.
