What this tool does

Markdown Editor & Live Preview is a browser-based workspace for writing and reviewing markdown with immediate feedback. It supports common GitHub Flavored Markdown workflows, including tables, task lists, strikethrough, fenced code blocks, and autolinks. As you type, the preview updates in real time so you can validate headings, list structure, link formatting, and documentation flow without context switching. A formatting toolbar helps insert common markdown syntax quickly, while split/editor/preview modes make it practical on both desktop and mobile layouts. The tool also generates a table of contents from headings for faster navigation in long documents, and includes word, line, and character statistics for writing progress. Export actions let you copy rendered HTML or download both HTML and markdown files for docs pipelines, release notes, and README workflows. Rendering is designed to be safe for online use by restricting unsafe raw HTML behavior and sanitizing markdown links, while keeping output close to expected markdown rendering semantics.
