Share Markdown as a Link — Free, Instant, No Signup for Viewers

The problem: where to host a one-off Markdown document

You have a technical write-up, a project README, a tutorial, or a formatted report. You need to share it with someone — a colleague, a client, a friend. Emailing a .md file is awkward (most people can't open it). Posting it on a blog takes setup. GitHub Gist works but the viewer needs to be comfortable with a code-centric interface. HackMD requires sign-up. Notion is heavy and slow to load.

What you really want: write the Markdown, get a link, send it. The viewer opens it in any browser and sees a beautifully rendered page. That's exactly what Note Shuttle does.

How Note Shuttle works

Note Shuttle is a lightweight Markdown publishing tool. You write in a split-pane editor with live preview, choose a time duration for the link, and publish. The generated link works in any browser on any device.

• Markdown rendering — headings, lists, code blocks with syntax highlighting, tables, images, blockquotes, and inline formatting are all supported.
• Time-limited links — choose from 10 minutes, 1 hour, 6 hours, 24 hours, or permanent. Great for sensitive or one-time documents.
• Encrypted publishing — encrypt with AES-256 in your browser before uploading. The server stores only ciphertext. Viewers enter a password to decrypt.
• No viewer account required — anyone with the link can read the content immediately.

When do you need to share a Markdown link?

• Sharing a technical document — you wrote a README, API guide, or architecture doc and need to send it to a colleague or client without emailing an attachment.
• One-time report delivery — a formatted report for a stakeholder. You set it to expire in 24 hours so it doesn't linger forever.
• Team review — your team needs to review a proposal. You publish it as a permanent link and share in Slack or email.
• Tutorial or blog post — you wrote a tutorial in Markdown and want to share it publicly without setting up a website.
• Quick documentation — you need to document something fast. Write Markdown, publish, share the link with your team.

How to share Markdown with Note Shuttle

1. Sign up and open the dashboard. Registration takes seconds — just pick a username and password.
2. Create a new document. Click “New Note” in the sidebar. The editor opens with a split-pane view: write Markdown on the left, see the rendered preview on the right.
3. Write your content. Use standard Markdown syntax. The toolbar provides quick access to headings, bold, italic, links, code blocks, lists, and more. You can also drag and drop images.
4. Click “Share” and choose a duration. Pick 10 minutes for burn-after-reading, or 6 hours / 24 hours / permanent depending on your needs. Free plan supports up to 6 hours; PRO and PLUS unlock 24 hours and permanent.
5. Click “Publish” and copy the link. The generated link looks like note.shuttlelab.org/p/abc123. Send it to anyone.

Common issues when sharing Markdown

Images not showing up

Make sure you uploaded the images through the editor (drag & drop or paste). Images are stored on Cloudflare R2 and served via CDN. If you pasted a local file path like ./image.png, it won't work — the image must be uploaded first.

Link expired unexpectedly

Check the duration you selected when publishing. A 10-minute link expires 10 minutes after creation, not after the first view. For longer-lived links, choose 6 hours, 24 hours, or permanent (PRO/PLUS required).

Viewer sees a blank page

This can happen if the document content is empty. Make sure your document has content before publishing. Also check that the link hasn't expired.

Need to update content after publishing

Edit the document in your dashboard and the published link will reflect the latest content. Note Shuttle stores the document, not a snapshot — so edits are live immediately.

Frequently Asked Questions

Do viewers need to sign up to see my shared Markdown?

No. Anyone with the link can view the content directly in their browser. No registration, no login, no app installation required.

What share durations are available?

Free plan offers 10 minutes, 1 hour, and 6 hours. PRO and PLUS plans ($5/year and $20/year) unlock 24 hours and permanent links.

Can I revoke a share link after publishing?

Yes. Go to the Shared panel in your dashboard and delete the share record. The link becomes inaccessible immediately.

Is the Markdown rendered or shown as raw text?

The shared page renders Markdown with headings, lists, code blocks with syntax highlighting, tables, images, and other standard Markdown features.

How is Note Shuttle different from GitHub Gist for sharing Markdown?

GitHub Gist is code-oriented with a developer-focused UI and requires a GitHub account to create gists. Note Shuttle is designed for quick publish-and-share: write Markdown, get a link, send to anyone. Viewers don't need any account, and you get time-limited links and optional encryption.

When to upgrade to paid

The free plan covers most casual use: 100 documents, 5 MB per image, and share links up to 6 hours. Upgrade to PRO ($5/year) if you need permanent links, 24-hour links, more than 100 documents, or larger images (up to 50 MB each). PLUS ($20/year) adds 500 MB per image for heavy image users.
