Markdown Editor & Generator

A complete Markdown workbench in your browser

Whether you're writing a README, an API reference, a changelog, a blog post or just notes, this editor gives you live preview, sensible defaults, and the export options you actually need — all running locally, no signup, no upload.

GitHub Flavored Markdown (GFM)

The parser is marked v12, the same engine that powers many static-site generators and code editors. It supports the GFM features developers expect:

• Tables with | col1 | col2 | syntax
• Task lists with - [ ] and - [x]
• Strikethrough with ~~text~~
• Fenced code blocks with ```language
• Autolinked URLs and emails

Built-in table of contents

Insert [[toc]] anywhere in your document and we'll generate a navigable list of all H2/H3/H4 headings. Useful for long READMEs and reference docs.

Code highlighting without bloat

Code blocks are syntax-highlighted with a minimal in-house engine that recognizes strings, comments, numbers and common keywords across JavaScript, Python, Go, Rust, SQL and shell. It's not as fancy as Prism or highlight.js but it adds under 1 KB instead of 80-200 KB. For most documentation purposes the difference is invisible.

Templates to start from

Pick one from the dropdown to instantly bootstrap:

• README — features, install, usage, API, contributing, license.
• API Reference — endpoints, auth, error codes, example requests/responses.
• Changelog — Keep-a-Changelog format with Added/Changed/Fixed/Deprecated sections.
• Blog post — hook → problem → attempt → breakthrough → solution → lessons.

Two export formats

• .md — your raw Markdown source.
• .html — a self-contained HTML file with embedded CSS, ready to drop into any web server or send by email. Looks clean on its own.

Safe HTML output

Markdown allows inline HTML, which means a malicious Markdown source could inject scripts or unsafe URLs (javascript:, etc.) into the HTML output. We sanitize everything with DOMPurify, the same library used by Gmail, ProseMirror and many other products. You can safely copy the HTML output and paste it into a CMS, blog or email without worrying about XSS.

Auto-save

Your draft is saved to your browser's localStorage every 2 seconds. Close the tab, come back tomorrow — your text will still be there. (It's local only — never uploaded.)

Keyboard shortcuts

• Cmd/Ctrl + B — wrap selection in bold
• Cmd/Ctrl + I — wrap selection in italic
• Cmd/Ctrl + K — insert a link (prompt for URL)

Privacy

Everything runs in your browser tab — markdown parsing, sanitization, rendering, saving. We don't upload your content, log your usage, or run analytics on what you type. The only network requests this page makes are the one-time CDN loads of marked and DOMPurify.

Common use cases

• Draft a GitHub README and paste it in directly.
• Write internal documentation that exports to a standalone HTML email.
• Quick-format a Slack post or forum reply.
• Convert old plain-text notes into beautifully rendered docs.
• Practice Markdown syntax with instant feedback.
