What is the Markdown Editor & Previewer?
A Markdown Editor & Previewer is a writing tool that renders Markdown into formatted HTML in real time as you type. Toollyz Markdown Editor & Previewer is a premium, distraction-free documentation workspace with a split-screen live preview that supports GitHub-Flavored Markdown — headings, bold, italic, strikethrough, tables, task lists, blockquotes, links, images, emoji shortcodes and syntax-highlighted code blocks. A formatting toolbar and keyboard shortcuts speed up writing, an automatic document outline lets you jump between sections, and a template library gives you ready-made README, blog, documentation, changelog and project-plan scaffolds. Live analytics count words, headings, links, images and more; everything auto-saves to your browser with version snapshots and undo/redo; and you can view the generated HTML or export to Markdown, HTML, PDF, DOC or plain text — all completely private and free.
