Show HN: WYSIWYG markdown editor for any GitHub repo
Last verified:
What is Dunkdown?
Dunkdown is a WYSIWYG markdown editor built by plannotator.ai that allows users to view and edit markdown files in any public GitHub repository without needing to remember markdown syntax. Instead of viewing raw markdown code, users get a visual editing experience similar to a word processor while working directly with GitHub repo markdown files.
The tool works by simply replacing 'github.com' with 'dunkdown.com' in any GitHub repository URL. For example, visiting dunkdown.com/mattpocock/skills opens that repository's markdown files in the Dunkdown editor. This makes it particularly useful for developers, technical writers, and anyone who works with GitHub documentation but struggles with markdown formatting.
Key features include visual markdown editing, support for any public GitHub repository, no account required to use, and seamless integration with existing GitHub workflows. The editor handles standard markdown syntax while providing a cleaner writing experience for README files, documentation, and other markdown content in repositories.
