Yes. xyzEditor is a 100% free, local-first  application. All your documents and data are stored securely in your own browser's local storage. We do not use any backend servers, so your data never leaves your device.

xyzEditor supports both LaTeX and AsciiMath. For LaTeX, wrap your equations in $$ for block maths or a single $ for inline maths. For AsciiMath, use backticks (`) and enable the AsciiMath Code Override in the editor's settings for lightning-fast inline typing.

You can create flowcharts, sequence diagrams, state diagrams, and more using Mermaid.js syntax. Simply create a Markdown code block and set the language to mermaid. The diagram will render and update automatically in the live preview.

xyzEditor generates high-quality PDFs using your browser's native print engine. You can force page breaks using --- or ***, and customize margins (in millimeters) directly in the app's settings. Click the "Print / Save PDF" button or press Ctrl+P to export.

GFM is an extension of standard Markdown that adds essential technical writing features like tables, task lists, strikethrough, and autolinking. xyzEditor fully supports GFM, ensuring your documents remain compatible with platforms like GitHub.

xyzEditor uses a unique section-based workflow. Instead of scrolling through a massive document, you can break your writing into smaller, manageable sections using the top Section Bar. This keeps the editor blazingly fast regardless of document size.
