LaTeX Tool

A collaborative LaTeX editor for the browser and the desktop

Write multi-file LaTeX documents together in real time, compile to PDF on a server or on your own laptop, and keep collaborating without an internet connection.

Edits reach co-authors in about 50 ms.

What it does

  • Real-time co-editing

    Several people edit the same document at once, in the browser or the desktop app, and see each other’s cursors.

  • AI writing help

    Copilot-style completions and grammar checks as you type, from any OpenAI-compatible model.

  • Compile anywhere

    Compile to PDF on the server, or on your own laptop: the desktop app installs its LaTeX engine on first run.

  • Works offline, together

    Laptops on the same network find each other and edit a shared folder over an encrypted connection, with no server at all.

  • Jump between PDF and source

    Click anywhere in the PDF to land on the line that produced it, and click an error to jump to its cause.

  • Multi-file projects

    Split a thesis into chapters; autocomplete suggests the project’s files as you include them.
