LatTeX Editor

Unleash your productivity and draft academic, scientific, or mathematical documents on the go with TeX Editor—a modern, lightweight, and privacy-respecting LaTeX/TeX editing environment designed from the ground up for Android.

Featuring a beautiful, native Material 3 interface, TeX Editor combines the simplicity of a distraction-free writing tool with the power of real-time equation rendering.

Key Features

Multi-Tab Document Editing: Open and work on multiple .tex files concurrently. Switch between tabs effortlessly to reference other drafts or copy notes.

Real-Time Math Previews: Render mathematical formulas, equations, matrices, formatting (\textbf, \textit), and lists instantly. Powered by MathJax 3 loaded via CDN, the preview window translates your TeX code into readable HTML output on the spot.

Line-Numbered Custom Editor: Write with confidence. A custom-built code editor includes a dedicated line-number gutter that scales dynamically as your documents grow.

LaTeX Accessory Keyboard: Speed up typing with a dedicated helper bar. Access brackets {} [] (), caret ^, underscore _, backslash \, dollar signs $ $$, and common symbols with a single tap.

Advanced Customization & Settings: Fine-tune your writing experience:

Adjust editor font size for readability.

Configure custom tab widths.

Enable/disable word wrap, spell checking, auto-save, and syntax highlighting.

Turn on auto-closing braces to write error-free code.

Privacy-First File Handling: The app leverages Android's native Storage Access Framework (SAF). We do NOT request broad read/write access to your device's files. The app only accesses the specific files you choose to open, ensuring absolute security for your personal documents.

Export & Sharing Tools: Save your documents, export them as DOCX files, copy formatted rich text to your clipboard, or share them as PDF files with classmates and colleagues.

Built-in Utilities: Stay on top of your writing with an integrated word counter, a search-in-files tool, a dedicated focus mode for distraction-free writing, and standard templates to kickstart new files.
