This plugin allows you to create documents with WordPress, and to share them with others so they can also read and edit. Share the unique link to let anyone edit, or restrict access to specific email addresses.
With the Gutenberg plugin, Docs supports real-time collaborative editing — multiple users can edit the same document simultaneously, seeing each other’s cursors and changes live.
<h3>Sharing</h3>
The share panel (in the document sidebar) lets you control access:
<ul>
<li>Anyone with the link — anonymous users get a randomly generated animal name and emoji avatar (e.g. “Anonymous Fox”). They can edit text but cannot upload files.</li>
<li>Specific people — invite collaborators by email. They receive a magic link to access the editor. Email-invited users can upload files.</li>
<li>Existing users — add collaborators from the user autocomplete. They get full editing and upload access.</li>
<li>Restricted — only the document author and invited people can access.</li>
</ul>
<h3>How it works</h3>
Documents live entirely in wp-admin — there’s no public frontend. Each doc gets a unique and secret shareable URL that opens the editor directly.
Anonymous visitors don’t create any database entries. Their identity exists only in a browser cookie and disappears when it expires.
Email-invited people are created as real WordPress users (without a role) so their edits show up in revision history. They log in via magic links sent to their email.

Your readers want your updates as quickly as possible, and we think we provide the easiest and most flexible publishing environment to make that happen. Sometimes though, that’s just not enough.
When you’re covering a fast-paced event — the latest Apple unveiling, an F1 Grand Prix or the Super Bowl — a full blog post for each individual update is a poor experience for your authors and your audience.
The <a href="https://wpvip.com/" rel="nofollow ugc">WordPress.com VIP Liveblog Add-On</a> was purpose-built to address these issues.
Here’s what makes it special:
<ul>
<li>Post updates right from the front end of your site (no need to use the <code>/wp-admin</code> dashboard).</li>
<li>Viewers of your liveblog get new entries served to them instantly and automatically, without needing to refresh.</li>
<li>Authors can drag and drop photos straight into the liveblog area, without separate browser tabs or windows.</li>
<li>No need for a separate site dedicated to liveblogging — every post can be a liveblog, even existing ones.</li>
</ul>
If you’d like to check out the code and contribute, <a href="https://github.com/Automattic/liveblog" rel="nofollow ugc">join us on GitHub</a> — pull requests are more than welcome.
