muse.ai

This plugin simplifies the embedding of videos hosted on <a href="https://muse.ai" rel="nofollow ugc">muse.ai</a> platform.
It does three things: 
 – whitelists muse.ai as an oEmbed provider (which lets you embed videos simply by pasting links), 
 – adds shortcodes as an alternative method of embedding that gives you a bit more control, 
 – adds an Elementor widget for embedding muse.ai videos.
The shortcodes are essentially a wrapper around muse.ai <a href="https://muse.ai/docs#embed-player" rel="nofollow ugc">embed library</a>.
To embed videos using oEmbed, simply paste a video link into a separate line in your post or page. For example:
<pre><code>https://muse.ai/v/VBdrD8v
</code></pre>
If you would like more control, you can use shortcodes. For example:
<pre><code>[muse-ai id="VBdrD8v" width="100%" title="0" logo="https://tinyurl.com/yourLogoPNG"]
</code></pre>
