About 1TX

Your words live on your device. Nowhere else.

Privacy Through Architecture

1TX is a free online text editor built on one architectural principle: your writing belongs on your machine and your machine alone. Every character you type into the 1TX text editor stays in your browser's local storage. Every file you save downloads directly to your device. The entire 1TX application runs as self-contained code inside your browser, with all processing happening right there on your machine.

The 1TX text editor operates entirely as client-side code within your browser, achieving full local operation where your browser handles everything from rendering to saving to storage. Your keystrokes travel from your fingers to your screen, and the journey is complete. Your content exists in exactly one place: your device. The 1TX architecture itself is designed to be the guarantee.

A Free Text Editor That Respects What You Place on It

1TX does not claim any rights, assertions, or license over content you create, draft, or edit within this online text editor. Your writing lives in your browser and your browser alone. Because your content exists exclusively on your own device, governed by your own file system and browser storage, your intellectual property and creative work remain entirely your own responsibility, under your own rights. The 1TX text editor provides the blank page. What you place on it is yours alone to manage, protect, and own.

A Browser-Based Text Editor Built for Writing That Flows

The 1TX text editor opens instantly. You type. That is the entire onboarding experience.

Word count, character count, reading time, and line count update live at the bottom of your screen. The 1TX online text editor offers dark mode, focus mode, zen mode, monospace and sans-serif typefaces, adjustable font sizes, and full keyboard shortcut support so you can shape the writing environment to match exactly how you think. Save your work as a .txt file whenever you choose. Drag and drop files directly into the 1TX editor window to open them.

Writing Modes

The 1TX text editor offers multiple purpose-built writing environments, each designed to support a different style of focus and workflow:

• Default mode provides a clean, paper-like writing surface with full toolbar access and all features visible
• Focus mode hides the toolbar and status bar, placing the entire screen at the service of your writing
• Zen mode expands the editor to full width with a single keypress, removing all visual distractions
• Monospace mode switches to a fixed-width typeface for structured writing, code drafting, or plain-text formatting
• Typewriter mode pairs a light background with monospace typography, evoking the feel of a classic writing machine
• Coder mode applies a dark background with green monospace text, designed for technical writing and code-adjacent work
• Blank mode reduces the interface to a pure white canvas with hidden chrome, surfacing controls only when needed
• Black mode provides the same minimal canvas in pure black, optimized for low-light environments and OLED screens

Over 80 Languages

The 1TX text editor speaks over 80 languages through fully localized interfaces. Every button label, placeholder, menu item, and status indicator is translated so you can write in the language that feels like home. Right-to-left languages including Arabic, Hebrew, Persian, and Urdu are fully supported with proper directional layout.

Keyboard Shortcuts

The 1TX text editor supports a complete set of keyboard shortcuts designed to keep your hands on the keys and your focus on the writing. Save, open, create new documents, toggle dark mode, enter focus mode, and switch typefaces without reaching for the mouse. Tab and shift-tab support is built into the editor for indentation control.

File Support

The 1TX text editor can open a wide range of plain-text file formats including .txt, .md, .log, .csv, .json, .js, .html, .css, .xml, .yaml, .ini, .conf, .sh, .py, .rb, .java, .c, .cpp, .go, .rs, .swift, .sql, and many more. Open files by clicking the open button, using the keyboard shortcut, or simply dragging and dropping them into the browser window. Save your work at any time as a .txt file that downloads directly to your device.

Zero Friction, Fully Intentional

You arrive at 1TX. You write. Everything runs locally, everything stays locally, and everything remains yours to keep, move, or delete as you see fit. The simplicity of this free online text editor is the entire point.
