Write, compile and read LATEX on your iPad and iPhone, offline.

TeXAnt is a mobile app with a full LuaLaTeX engine built in, so your documents compile without a connection. Missing packages install in a tap, and your projects sync to your own cloud or Git.

Compiles with LuaLaTeX. Most pdfLaTeX documents compile unchanged; shell escape (minted, pythontex) is not available.

From the first line to the final PDF, in one app.

Compile on your device, even offline

A full LuaTeX engine is part of the app. Your document compiles on your iPad or iPhone, with no upload and no waiting on a server, so it works on a plane just as well as at your desk.

  • Arabic, Hebrew, Hindi and other complex scripts come out right, and any OpenType font can be used. Plain TeX documents work too, with one switch in settings.
  • Two ways to compile from one button: Full starts clean, Fast reuses the last run's auxiliary files while you iterate.
  • Reruns by itself until cross-references, contents, lists of figures, indexes and glossaries settle.
  • BibTeX, biblatex (Biber), makeindex, glossaries and nomencl run as part of the compile.
  • Stop ends a runaway compile at any point, including loops inside Lua code.
  • The Problems panel lists errors and warnings, with the full log one tap away. If a helper step fails, you still get the PDF and a clear warning.
  • Markdown files compile too: the same button turns a .md file into a PDF saved next to it.

Your research belongs to you.

Drafts, data and unpublished results stay on your iPad or iPhone while you write and compile. There is no advertising identifier and no ad network in the app.

Read the Privacy Policy

Stays on your device

  • Your source, .bib files and figures. The engine compiles on the device, so nothing is uploaded to build the PDF.
  • The app's local database, encrypted with a key created on your device and kept in its Keychain.
  • Diagnostics, which are anonymous, off by default, and never include file names, source or PDFs.

Leaves only if you connect it

  • Files you sync, to your own cloud account and nowhere else.
  • Commits you push, to the Git remote you chose.
  • Requests to the AI assistant, sent straight to the provider whose key you added.

Take your LATEX projects with you.
