ar5iv Editor

A live HTML preview for LaTeX, in the browser.

A LaTeX editor with a web-native live preview. Source TeX is sent to the backend over a WebSocket; the server runs latexml-oxide (a pure-Rust LaTeXML port) to produce HTML5 with native MathML, and the rendered fragment is morphed back into the preview pane.

This is the Rust successor to the Perl / Mojolicious ltxmojo plugin for LaTeXML.

Sessions & privacy

Each editing session is anonymous and lives in a server-side scratch directory. After 10 minutes of inactivity the session is deleted from disk: the source files you uploaded or edited, the rendered HTML, and any associated state are gone. No accounts, no long-lived storage. Save anything you want to keep with the download button before stepping away.

Every piece of user-uploaded data is erased on session expiry and is not logged or retained elsewhere. Users are responsible for only uploading materials they have sufficient rights to convert and view here.
