TeXslate App
TeXslate is a native LaTeX/XeTeX editor for Android tablets (and phones) that compiles your documents right on the device — no cloud service, no account, no companion PC. Editor, LaTeX compiler and PDF preview live together in one screen.It is powered by the Tectonic engine (XeTeX), so modern Unicode and fontspec/\setmainfont just work.
Features:
* Full LaTeX/XeTeX compilation on-device, offline
* Live PDF preview — split view on tablets, tabbed layout on phones
* LaTeX syntax highlighting, auto-compile on pause, jump-to-error
* Multi-file projects: \input / \include and bibliography
* Curated fonts bundled (Latin Modern, TeX Gyre) usable by name via \setmainfont; Android system fonts and your own font folder also work
* Search & replace, go-to-line, comment toggle, document outline, custom templates
* Optional AI assistant (Anthropic / OpenAI / Gemini) — off by default, used only if you add your own API key
Good to know:
* The first compile downloads the TeX packages it needs (internet needed that one time). Afterwards compiling works offline; when a connection is available, the app checks the bundle server and fetches packages a document uses for the first time.
* The optional AI assistant contacts third-party services only when you enable it with your own key.
Free software, licensed under GPL-3.0-or-later. Built for tablets first: split view, external keyboard and stylus.
