Frequently asked questions

What is the Best Answer Hub Markdown Editor?

The Best Answer Hub Markdown Editor is a free browser-based split-pane editor that lets you write Markdown on the left and see a live preview on the right. It supports GitHub Flavored Markdown including tables, task lists, fenced code blocks, strikethrough, and autolinks. You can export your work as a .md file or as styled .html. Everything runs locally in your browser, so your text is never sent to any server.

Is the Markdown Editor free to use?

Yes, the Best Answer Hub Markdown Editor is completely free with no usage limits, no signup, and no watermarks. You can write and export as many documents as you want. Unlike Typora, which costs $15 for the desktop app, or HackMD, which gates collaboration behind a paid plan, the Best Answer Hub Markdown Editor gives you full editing and export capabilities at zero cost.

How do I use the Markdown Editor?

Type or paste your Markdown into the left pane of the Best Answer Hub Markdown Editor. The right pane updates instantly as you type. Use the toolbar buttons to insert common formatting like bold, italic, headings, links, images, code blocks, and tables. Your work is auto-saved to your browser's localStorage every few seconds. When you are finished, click Download Markdown to save your .md file, or Download HTML to get a styled page you can publish anywhere.

What is Markdown and why do developers use it?

Markdown is a lightweight markup language created by John Gruber in 2004. It lets you format text using plain-text syntax like **bold**, *italic*, and # headings. Developers love it because it is readable in raw form, works in every text editor, and converts cleanly to HTML. It is the standard format for README files on GitHub, documentation on GitLab, posts on Reddit and Stack Overflow, and notes in Notion and Obsidian. The Best Answer Hub Markdown Editor supports all standard syntax plus GFM extensions out of the box.

Does this editor support GitHub Flavored Markdown?

Yes. The Best Answer Hub Markdown Editor uses the marked.js parser with GitHub Flavored Markdown (GFM) enabled. This means tables, task lists, fenced code blocks with syntax highlighting, strikethrough, and autolinks all render correctly. The preview pane uses github-markdown-css to match GitHub's visual style as closely as possible, so you can preview your README before pushing it to a repository.

Can I use this editor offline?

Yes. After you load the page once, the Best Answer Hub Markdown Editor works without an internet connection. All parsing, previewing, and exporting happens locally using JavaScript. The only time you need a connection is for the initial page load, which downloads the marked.js and highlight.js libraries. Once cached, the tool works entirely offline.

Is my text sent to a server?

No. Your text never leaves your browser when using the Best Answer Hub Markdown Editor. The editor uses client-side JavaScript to parse Markdown and render HTML, with no network requests when you type, preview, or export. You can verify this by opening the Network tab in your browser's Developer Tools and confirming zero outgoing requests after the initial page load. This makes the editor safe for drafting sensitive documentation, private notes, or proprietary README files.

How do I export my Markdown document?

Click the Download Markdown button in the Best Answer Hub Markdown Editor to save your raw .md file, which you can open in any text editor or commit to Git. Click Download HTML to get a self-contained HTML file with GitHub-like styling and syntax highlighting that you can open in a browser, attach to an email, or host as a static page. You can also click Copy HTML to grab just the HTML body for pasting into a CMS or blog platform.

What syntax highlighting languages are supported?

The Best Answer Hub Markdown Editor uses highlight.js with its common language pack, covering JavaScript, TypeScript, Python, Java, C, C++, Go, Rust, Ruby, PHP, Bash, SQL, HTML, CSS, SCSS, JSON, YAML, and plain text. Use a fenced code block with a language tag like ```python and the editor applies the correct color scheme automatically. If the language is not recognised, it falls back to automatic detection or plain text.

Can I preview how my README will look on GitHub?

Yes. That is one of the primary use cases for the Best Answer Hub Markdown Editor. The preview pane uses github-markdown-css, which replicates GitHub's typography, spacing, heading sizes, link colors, table borders, and code block styling. While no third-party preview can be pixel-perfect due to GitHub's internal theming engine, this tool gets you about 95 percent of the way there, the fastest way to catch formatting mistakes before you commit your README.

How do I insert a table of contents?

Click the TOC button in the Best Answer Hub Markdown Editor toolbar. The editor scans your document for headings, generates a nested list of anchor links, and inserts it at your cursor position. If you add or remove headings later, delete the old TOC and click again to regenerate it. The TOC uses standard Markdown link syntax like [Heading](#heading), which works on GitHub, GitLab, and most static site generators including Hugo and Jekyll.

Does the editor auto-save my work?

Yes. The Best Answer Hub Markdown Editor saves your document to your browser's localStorage every 2 seconds while you type. If you close the tab or refresh the page, your text is restored automatically when you return. Auto-save is completely local, with nothing uploaded to a cloud server. If you want to start fresh, click the Clear button. Note that localStorage is cleared when you clear browser data or use incognito mode.

Can I open an existing Markdown file?

Yes. Click the Open File button in the Best Answer Hub Markdown Editor or drag and drop a .md or .txt file directly onto the editor pane. The file contents will replace the current document. There is a 1 MB file size limit to prevent browser performance issues. If you accidentally overwrite your content, use your browser's Undo shortcut or close the tab without saving, but localStorage updates every 2 seconds, so act quickly.

What are the best Markdown editors in 2026?

For desktop, Typora remains popular for its distraction-free WYSIWYG experience at $15. Obsidian is excellent for knowledge management with a free personal tier. For browser-based editing, Dillinger and StackEdit are the most established alternatives, but both push cloud sync and account creation. The Best Answer Hub Markdown Editor differentiates itself by being lighter, faster, fully offline-capable, and requiring zero accounts, ideal for quick drafts, README previews, and documentation work where privacy matters.

What is the difference between CommonMark, GitHub Flavored Markdown, and standard Markdown?

John Gruber created the original Markdown specification in 2004, but it left many edge cases undefined. CommonMark, launched in 2014 by a group including Jeff Atwood, standardised those ambiguities into a formal spec. GitHub Flavored Markdown (GFM) extends CommonMark with tables, task lists (- [ ] syntax), strikethrough, fenced code blocks, and autolinks. It is now the default on GitHub, GitLab, and Discourse. The Best Answer Hub Markdown Editor uses the marked.js GFM parser, so your tables, task lists, and fenced code blocks render exactly as they do on GitHub. Reddit uses a CommonMark dialect, while Hugo and Jekyll support configurable GFM subsets.
