What is md?

This project is a Markdown editor designed specifically for publishing articles to WeChat's public account platform. Writing for WeChat can be frustrating because the platform uses its own formatting system that does not accept standard Markdown. This editor solves that by letting you write in plain Markdown and then automatically converting it into properly styled content that pastes cleanly into the WeChat editor. The editor runs in a web browser and is available as a hosted tool at md.doocs.org, or you can run it yourself using Docker, a command-line tool, or by building from source. It also packages as a Chrome browser extension. For people who just want to write and publish without dealing with tools, the hosted version requires no installation. Beyond basic Markdown, the editor supports math formulas, code blocks with syntax highlighting, diagrams drawn in text notation, and custom color themes and CSS styles. Images can be uploaded to one of more than a dozen supported storage services including GitHub, Cloudflare R2, several Chinese cloud providers, and Telegram. You can also configure a custom upload endpoint. The editor integrates with several AI models, including DeepSeek and OpenAI, to assist with writing and formatting. Draft saving is built in. The README is written primarily in Chinese, as the tool is aimed at Chinese-language WeChat content creators. The full README is longer than what was shown.
