WWWD

A browser‑based Markdown editor that runs entirely locally, offering a split‑pane view with instant rendering of GFM, tables, footnotes and code blocks. It includes syntax highlighting for over a hundred programming languages, an image manager for uploads, URLs and drag‑and‑drop, and one‑click export to PDF, HTML and Word formats.

The tool supports real‑time collaboration through shared rooms, showing teammates’ cursors and changes without requiring accounts or sign‑up. Every edit is automatically saved as a version snapshot, allowing users to browse a document timeline and restore earlier states.

Designed for writers, developers, students and professional teams, the editor emphasizes privacy—no data leaves the browser—and provides all features without any subscription, premium tier or hidden cost. It is ready to use instantly in any modern browser.
