What the editor supports
The editor follows CommonMark, the standard Markdown specification, plus the GitHub additions people use most: tables with column alignment, task lists (- [ ] and - [x]), strikethrough with ~~ and automatic links for web addresses. Headings get IDs so you can link to sections. We checked the renderer on 300 generated documents against the markdown-it library, a widely used CommonMark parser, with the same extensions switched on, and all 300 produced identical HTML. Everything runs in your browser; nothing you type or choose is uploaded.
For safety, raw HTML in your Markdown is shown as text rather than run, and only web, email, phone and relative links become clickable. The draft is kept in your browser's storage on this device, so it's still there when you come back.
Worked example
The sample note, Python Basics: Study Notes, shows each feature: a heading, a four-item task list with two items ticked, a fenced Python code block, a three-row table with a centred column, a tip in a blockquote, a numbered list and a link to the official Python tutorial. Download .html saves it as python-basics-study-notes.html, a complete page with clean styling that opens in any browser.

Frequently asked questions
Is my writing private?
Yes. It stays in your browser on this device; clearing your browser data removes the draft.
Can I use HTML inside Markdown?
It's shown as text here, for safety. Use the exported HTML file if you need to add custom tags.
Is the Markdown editor free?
Yes. You can open the Markdown editor and fill in every option without signing up. When you download or copy your document for the first time, we ask once for your name and WhatsApp number; after that it, and every other Uncodemy tool, opens straight away.
