Is there a way to have a different chatroom for each post?

Yes, it is possible, but requires a little PHP coding and a minimal WordPress knowledge. First, you have to find which post types you wish to handle. A post type that represents regular blog entries is named “post”, for regular pages it is: “page”. For custom post types please ask authors of your theme. Prepare a list of such post types and add this code to theme’s functions.php file:

define('WISE_CHAT_POST_TYPES', ['post']);
add_filter('the_content', function ($content) {
	global $post;
	if (!$post instanceof WP_Post) {
		return $content;
	if (in_array($post->post_type, WISE_CHAT_POST_TYPES)) {
		$channel = ucfirst($post->post_type).' channel #'.$post->ID;
		$windowTitle = $post->post_title;
		return $content . sprintf('[wise-chat channel="%s" window_title="%s"]', $channel, htmlentities($windowTitle));
	return $content;

Populate WISE_CHAT_POST_TYPES constant with any post type you want, e.g.: [‘post’, ‘page’, ‘books’, ‘companies’], etc. This will output the chat under every single post as configured in WISE_CHAT_POST_TYPES. Each post will have its own dedicated public channel accessible to anyone who visits the post.
