Inkdown
A WYSIWYG Markdown editor, improve reading and editing experience
Inkdown (bluestone) is a Markdown reading, editing, and sharing tool. Almost fully compatible with the GitHub Flavored Markdown standard, while extending the Mermaid graphics and Katex formula, supporting light and dark styles, and somewhat different from other WYSIWYG editors, Inkdown does not pursue complete customization. Its core goal is comfortable reading, smooth editing of Markdown, and document sharing in the simplest way possible. As a document publisher, markdown source code mode is undoubtedly efficient and free, but as a note, it is not conducive to reading. The table element of markdown is not conducive to writing, and the double-column mode is not conducive to focusing, so the Inkdown Editor was developed. It combines rich text with markdown editing habits to help you record daily, and saves it in standard markdown format, which allows your notes to be used anywhere and backed up in any way. -
