What is a Markdown editor?
A Markdown editor lets you write formatted text using simple syntax — like **bold**,*italic*, and # headings — that converts to HTML in real time. Markdown is the standard for README files on GitHub, documentation sites, blog posts, technical writing, and most modern note-taking apps (Notion, Obsidian, Bear, Logseq, Roam). This free editor renders GitHub Flavored Markdown (GFM) with full support for tables, task lists, fenced code blocks, and autolinks. Everything runs in your browser — your content never leaves your device, and your draft is autosaved to localStorage so a refresh won't lose your work.

Frequently Asked Questions
What is GitHub Flavored Markdown (GFM)?
GFM is the dialect of Markdown used by GitHub, GitLab, Bitbucket, and most modern documentation tools. It extends the original Markdown spec with tables, task lists, strikethrough, autolinks (bare URLs become clickable), and fenced code blocks with language hints. This editor uses GFM by default.
Where is Markdown used?
Markdown is the default format for GitHub README files, GitHub/GitLab issues and pull requests, static site generators (Jekyll, Hugo, Astro, Next.js MDX), documentation tools (Docusaurus, MkDocs, GitBook), blog platforms (Ghost, Medium import/export), note-taking apps (Notion, Obsidian, Bear, Logseq), and messaging apps (Slack, Discord, Microsoft Teams). It's the universal format for technical writing.
Can I use HTML inside Markdown?
Yes. Markdown processors allow inline HTML for elements Markdown doesn't support natively — like<video> embeds, <details> collapsible sections, or custom layout. This editor passes raw HTML through unchanged when used inside Markdown.
Is my content private?
Yes — 100%. Markdown rendering happens entirely in your browser, and your draft is stored only in your browser's localStorage. Nothing is sent to a server. Clear your browser data if you want to wipe the autosaved draft.
How is this different from Notion or Obsidian?
Notion and Obsidian are full note-taking apps with file management, backlinks, and sync. This is a focused tool for converting Markdown to HTML quickly — ideal for one-off documents, README drafts, or previewing how your Markdown will render before publishing.
Why is the rendered output missing some styling I expect?
This editor renders the structural HTML from your Markdown but does not apply syntax highlighting inside fenced code blocks or render math (LaTeX). For a publishing platform with full styling, internal linking, and SEO scoring, try Quillly — it's built on the same Markdown foundation.
