We have a small button that you can embed on your website that will create a 'Save to ReadCast' button. It works in the same way social sharing buttons work.
All you need to do is include this HTML where you want your Save button to be. We would advise you to only have one of these buttons on a single page.
<div id="readcast-save"></div> <script src="https://readcast.app/embed.js"></script>
