Your data never leaves your browser

MarkOut runs entirely in your browser. Your Markdown is never sent to any server — it is parsed locally by marked.js and copied directly to your clipboard. The only external request is loading the marked.js library from a CDN when you first open the page.

MarkOut is a browser-based tool that converts Markdown to rich text and copies it to your clipboard. Paste the result directly into Outlook, Teams, or any app that accepts formatted text — no plugins, no account, no installation required.

Outlook’s compose window accepts HTML-formatted clipboard content, but raw Markdown is just plain text. MarkOut converts your Markdown to HTML and writes it to the clipboard in a format Outlook recognises as rich text — so headings, bold, bullets, and tables all paste correctly.

Paste your Markdown into the left pane. MarkOut automatically detects Markdown, renders a preview on the right, and copies rich text to your clipboard in one step. Then switch to Outlook and paste.

You can also click Copy rich text manually after editing.

Copy the sample email below, paste it into MarkOut, and hit Copy rich text. Then paste into a new Outlook message. That is the whole workflow.

Better yet — forward it to a colleague and spread the word:

Subject: You need to try MarkOut Hey, I just found this tool called **MarkOut** and it is a game-changer for anyone who writes emails in Markdown. Here is what it does: 1. You **paste Markdown** into the left pane 2. It instantly converts it to **rich text** (headings, bold, bullets, code blocks — everything) 3. One click copies it to your clipboard as formatted HTML 4. **Paste into Outlook** and it looks perfect No install, no plugins, no account. Just open [markout.cloud](https://markout.cloud) in your browser. ### Why I like it - I draft emails in Markdown anyway — this skips the "now make it look nice" step - The `Subject:` line detection is clever — it pulls out your subject automatically - There is a **keyboard shortcut** you can install so you never even open the browser - It runs entirely in your browser — nothing is sent to a server Try it: [markout.cloud](https://markout.cloud)

When this checkbox is on, MarkOut detects a subject line at the top of your content — either a Subject: ... line or a top-level # Heading — and displays it separately in the header with its own Copy button.

This lets you paste the subject into the Outlook subject field and the body into the message body in one workflow.

Yes — any app that accepts HTML clipboard content will receive formatted text. This includes Microsoft Teams, Gmail, Notion, Confluence, and most rich-text editors. Results may vary depending on how each app handles pasted HTML.

Writing rich-text (HTML) content to the clipboard requires the clipboard-write permission, which browsers prompt for on HTTPS sites. Once granted, the permission persists for the session. MarkOut never reads your clipboard — only writes to it.

Not yet — MarkOut is currently a web app only, but there is a keyboard shortcut installer for Windows that lets you convert clipboard Markdown without opening the browser. A browser extension may follow — if that is important to you, open a feature request on GitHub.
