If you write something like “@nick, how are you?” this plugin will search for @nick’s url in the comment list of the current post and will convert his/her name to a link.

This plugin adds a field to the WordPress editor sidebar which allows you to paste the URL to a social media post that is associated with the post on your WordPress site. The URL is then stored in post meta and can be used to e.g. display the relevant social media post URL in the frontend.
By default, the plugin will append the link to the post content in the frontend. This can be disabled via filter though in favor of manual output elsewhere.
You can paste any URL into the field, regardless of social media platform. That said, the plugin will automatically recognize certain providers and adjust the message displayed in the frontend accordingly, referencing the specific provider when possible. The following providers are explicitly supported (in alphabetical order):
<ul>
<li>Bluesky</li>
<li>Facebook</li>
<li>GitHub</li>
<li>Instagram</li>
<li>LinkedIn</li>
<li>SoundCloud</li>
<li>Spotify</li>
<li>Threads</li>
<li>TikTok</li>
<li>Twitter</li>
<li>Tumblr</li>
<li>WordPress</li>
<li>WordPress.com</li>
<li>X</li>
<li>YouTube</li>
</ul>
No third-party APIs are called by this plugin and no data is sent to any of these providers by the plugin.

Relevant Social URL

Allows to associate a social media post URL with each post, and optionally to display a link to it in the frontend.
