What is md-html-forge?

md-html-forge is a browser-based editor that converts Markdown into polished, book-quality HTML using a library of pre-built components. Instead of producing plain, unstyled output, it routes your Markdown through a curated set of 30+ visual building blocks, things like headers, tables, timelines, metrics, and callout boxes, so the result looks like a professionally designed document rather than a bare webpage. The way it works is through "forge directives," which are plain HTML comments embedded in your Markdown file. A comment like "use header" tells the engine to render that section with the header component. Because these directives are just comments, the file stays valid Markdown and readable in any plain text editor. The editor shows your Markdown on the left and a live HTML preview on the right, with two-way sync: clicking a checkbox in the preview writes the change back to the Markdown. You can save a Brand Pack, a set of colors, fonts, and spacing values stored in your browser's localStorage, so every document you produce inherits the same visual identity. No server or account is required. When finished, you can export the result as standalone HTML with no external dependencies, or as a PNG image. The project is also designed to work with AI assistants: the component library is exposed via structured endpoints so a language model can be given the component syntax and produce forge-formatted Markdown directly. md-html-forge is built with TypeScript and Next.js.
