StackEdit

StackEdit is a powerful in-browser Markdown editor that provides web writers with an unrivalled writing experience. The editor features unique Markdown syntax highlighting with refined text formatting that helps users visualize the final rendering of their files. Built on the PageDown editor used by Stack Overflow, it provides convenient formatting buttons and shortcuts for a WYSIWYG-style editing experience. The Scroll Sync feature accurately binds the scrollbars of the editor and preview panels, ensuring users always keep an eye on the output while writing. The tool supports file synchronization with Google Drive, Dropbox, and GitHub, and can publish documents as blog posts to Blogger, WordPress, and Zendesk. Collaboration features allow multiple users to share workspaces and collaboratively edit the same file in real time, with automatic change merging. Users can insert inline comments and embed collaborator discussions in files, similar to Microsoft Word and Google Docs. The editor supports offline writing, accessible without an internet connection like any desktop application. StackEdit fully supports GitHub Flavored Markdown, LaTeX math expressions, UML sequence diagrams and flowcharts, ABC music notation, and emoji. Created by Benoit Schweblin and open source on GitHub, it has become a go-to tool for technical writers, bloggers, and content creators who need a feature-rich Markdown editing environment directly in their browser.
