Learn about everything JotBird supports for fast, private publishing.

Introduction

What is JotBird?

JotBird is a fast, privacy-first way to write and publish Markdown to the web. You can use it instantly without an account, or create a free account to sync published documents across devices and extend link lifetimes. With a Pro subscription, your published links never expire.

This guide explains how JotBird works, what it supports, and how the lifetime of published content is managed.

Overview

How JotBird Works

JotBird runs primarily in your browser. Until you publish, your content stays on your device.

When you publish, JotBird renders your Markdown to a static HTML page and hosts it at a shareable URL.

Each published document has:

  • One document
  • One URL
  • One clear owner

There are no projects, folders, or sites to manage. That simplicity is intentional.

If you create an account, your published documents are associated with your account and synced across devices. Drafts remain local to the device where you're editing.

JotBird is not a CMS, blogging platform, or collaborative editor. It's infrastructure for Markdown — optimized for speed, clarity, and low friction.

Editing

Writing and Previewing

The editor is split into two panes:

  • The editor pane, where you write Markdown
  • The preview pane, which renders your content in real time

The preview reflects exactly what will be published. There's no separate build step and no formatting surprises after the fact.

On smaller screens, the preview may be hidden or toggled by default to prioritize writing space. This behavior is intentional and may evolve as mobile usage patterns become clearer.

Drafts are saved locally in your browser. This allows fast, offline-friendly editing and avoids storing unfinished writing on our servers.

Draft changes are not synced across devices until you publish.

Publishing

Publishing, Updating, and Deleting

Publishing is a one-click operation. Once published, your document is available at a shareable URL.

Ownership

When you publish a document:

  • If you're signed in, the document is associated with your account
  • If you're not signed in, ownership is tied to your current browser and device

As the owner, you can:

  • Update the page using the Update button
  • Unpublish the page permanently from the document menu

Updates keep the same URL for the lifetime of the link.

Expiration

Content Lifetime and Expiration

Published URLs in JotBird are temporary by default.

Expiration depends on your account type:

  • Without an account: URLs expire after 30 days
  • With a free account: URLs expire after 90 days
  • With Pro: URLs never expire — your published links are permanent

For anonymous and free account publishes, expiration is fixed and does not automatically extend when content is updated.

When a URL expires:

  • The link stops working
  • The HTML page and hosted images are deleted
  • The content is removed from JotBird's servers

This design keeps JotBird lightweight, private, and predictable.

JotBird Pro

JotBird Pro ($29/year) gives your published links permanent URLs that never expire. When you upgrade, all your existing documents are migrated to permanent storage automatically.

If your subscription lapses, existing Pro links remain permanent. New publishes revert to 90-day expiration until you resubscribe.

Republishing

Expiration does not affect your local content.

With a free account: Republishing renews the same URL and starts a new 90-day lifetime.

Without an account: Republishing creates a new URL with a new 30-day lifetime.

With Pro: URLs are already permanent — republishing simply updates the content.

Files

Importing Files

JotBird supports importing local Markdown files.

Using File → Import…, you can load a .md file from your device into the editor. The file is read locally and is not uploaded unless you choose to publish.

Using File → New, you can start a fresh document. If you have unsaved changes, JotBird will prompt before clearing the editor.

Exporting

Exporting Content

You don’t need to publish in order to export your work. JotBird supports the following export options:

  • Export Markdown — exports a .md file with image assets (if any)
  • Export as HTML — downloads a standalone HTML file with image assets (if any)
  • Print or save as PDF — uses your browser’s print dialog

All exports happen locally in your browser.

Markdown

Supported Markdown

JotBird supports a practical, publishing-focused subset of Markdown.

This includes:

  • Headings
  • Bold, italic, and strikethrough
  • Highlighted text
  • Inline code and code blocks
  • Blockquotes
  • Bulleted and numbered lists
  • Task lists
  • Links and images
  • Emoji shortcodes
  • Tables
  • Footnotes
  • Subscript and superscript
  • Math expressions (KaTeX)
  • GitHub-flavored Markdown conventions

YAML frontmatter (a ----delimited block at the top of a file) is recognized and ignored. It will not appear in the preview or on the published page.

HTML in Markdown

JotBird supports a small subset of inline HTML so previews and published pages render consistently.

Commonly supported tags include paragraphs and line breaks (p, br), links (a), lists (ul, ol, li), emphasis (strong, em), code (code, pre, kbd), blockquotes, headings (h1h6), and tables (table, thead, tbody, tr, th, td).

For safety, dangerous HTML is stripped during publishing. This includes <script>, <iframe>, <object>, <embed>, inline event handlers (such as onclick), and JavaScript URLs. Images are allowed, but unsafe sources are removed.

HTML comments (<!-- like this -->) are supported and stripped from the rendered output. They’re useful for notes, annotations, or temporary content that shouldn’t appear in the published page.

Images

Images

You can paste, drag, or upload images directly into the editor.

When you publish:

  • Images are hosted automatically with the page
  • Image URLs remain valid for the lifetime of the page
  • Images are deleted when the page expires or is unpublished

JotBird is designed for document-level imagery, not large media libraries.

Privacy

Privacy and Analytics

JotBird does not track visitors to published pages and does not include third-party analytics scripts on shared content.

Visitor behavior on shared pages is intentionally private.

Limits

Limits and Fair Use

JotBird is designed for real documents — not bulk file hosting or automated publishing.

With an account, you can publish unlimited documents, subject to reasonable use.

Typical documents — including long articles, lesson plans, technical notes, and reference material — are well within supported limits.

If usage significantly exceeds normal document publishing (for example, automated mass publishing or file storage abuse), we may apply limits or restrictions.

FAQ

Frequently Asked Questions

Do I need an account?

No. You can use JotBird without an account.

Creating a free account lets you:

  • Sync published documents across devices
  • Publish unlimited documents
  • Renew links for up to 90 days

Upgrading to Pro ($29/year) gives you permanent links that never expire.

Can other people edit my published page?

No. Only you can update or delete a page you published.

Are URLs permanent?

By default, no. Published URLs expire after 30 days without an account, or 90 days with a free account. With Pro, URLs are permanent and never expire.

Do updates extend the lifetime of a URL?

For free accounts and anonymous use, no. Editing or updating a page does not extend its expiration.

With a free account, republishing renews the same URL for another 90 days. Without an account, republishing creates a new URL. With Pro, URLs are already permanent — updates simply replace the content.

Can I access my documents on another device?

If you're signed in, your published documents are available on any device where you log in.

Drafts remain local to the device where they were created until published.

Is JotBird open source?

No. JotBird is a proprietary product.

Does JotBird support math notation (LaTeX)?

Yes. JotBird supports math expressions using KaTeX, a fast math typesetting library.

Use $...$ for inline math (e.g., $E = mc^2$) and $$...$$ for block equations. Math renders in both the preview and published pages.

Does JotBird support Mermaid diagrams or other diagram formats?

Not yet.

Mermaid and other text-based diagram formats are not currently rendered. Diagram blocks will appear as plain code blocks in both the preview and the published page.

Diagram support is a common request and on the roadmap, but the current goal is to keep the publishing pipeline fast and predictable.

Clear reports help keep JotBird small, reliable, and predictable.

JotBird is intentionally simple. If it feels boring in the best possible way, it’s working.
