Who runs this and why
- MD Editor is a small independent project, operated from Taiwan.
- It is free with no catch: no ads, no investors, no data business.
- The editor runs entirely in your browser, with no account and no upload.
- Every guide is written twice, once in English and once in Traditional Chinese.
An editor you reach for without thinking
MD Editor sets out to do two things well. The first is the tool itself. It loads at once, works without an account, previews exactly what you will publish, and sends not one character of your writing to a server.
A library, not a landing page
The second job is teaching. Plenty of free editors wrap a thin marketing page around a text box. We would rather write the guides properly, so the library carries you from "what is Markdown?" to fluent work with tables, GitHub Flavored Markdown and the rest.
Why the .tw in the name
MD Editor is operated from Taiwan, and the domain says so on purpose. Nearly all the good Markdown writing on the web is in English. Taiwanese developers, students, technical writers and note-takers deserve the same depth in their own language.
So the Chinese here is natural Traditional Chinese, written for readers in Taiwan. It is not machine translation, and it is not simplified-character text with the glyphs swapped. Every page exists twice, from the editor interface to the longest guide.
What makes MD Editor different
Privacy is architectural, not contractual
Most online editors promise not to misuse your documents. We built the site so the question never comes up. Parsing, previewing, autosaving and exporting all run in JavaScript inside your tab, and drafts stay in your own device's localStorage.
There is no document database on our side, no upload endpoint and no account system. Nothing here needs an account, so we never built one. The privacy policy lists the few plain things our server does see.
Free, with no catch to look for
The fair question about any free tool is what pays for it. Here the answer is nothing much. The site runs no ads, has taken no investment, and sells no data, mainly because it never collects any data worth selling.
The bills come out of the operator's own pocket, and they are small. The editor does its work on your computer rather than on our servers, which is the cheapest architecture there is.
The preview tells the truth
The editor renders GitHub Flavored Markdown, the dialect used by GitHub, GitLab and most modern tools. Tables, task lists, strikethrough and fenced code blocks appear exactly as they will in your README or blog post. There are no dialect surprises after you publish.
The tool and the textbook live together
When a guide shows you a syntax pattern, the editor is one click away to try it. When the editor makes you curious about a feature, the complete Markdown guide explains it properly. That is learning by doing, with both halves in one place and in both languages.
What the library contains
Start here if the format is new to you
Two pages carry beginners. What is Markdown? is a plain-language introduction with history and real examples, and the FAQ answers fifteen common questions, each on its own page.
References to keep open while you write
- The complete Markdown guide - Every element of the syntax, from headings to footnotes, with correct usage and the traps.
- Markdown cheat sheet - The whole syntax on one scannable page, built to sit in a pinned tab.
- Markdown tables - Building, aligning and fixing tables, the syntax people struggle with most.
- GitHub Flavored Markdown - What GFM adds to the original Markdown, and why it became the default.
- Markdown vs HTML - How the two relate, which to use when, and how to mix them safely.
Each of those pages exists in English and in Traditional Chinese, and the set keeps growing.
Tip: If a topic still confuses you after you read our page on it, treat that as a bug in the guide rather than a gap in you. Tell us which sentence lost you and we will rewrite it.

Who you are writing to
This is a small project, so feedback reaches a human quickly. Found a rendering bug? Spotted an awkward sentence in the Chinese guides? Want a feature in the editor, or a topic covered in the library? The contact page gives the one address and the details worth including.
We read everything that arrives. Bug reports in particular are acted on fast.
One honest reminder
Because everything runs in your browser, your drafts live in localStorage on your device and nowhere else. Export anything important as a .md file. It is your document, so keep a copy that is genuinely yours.
