Elementor is a page builder plugin for WordPress that was created by Pojo Me Digital LTD. It aims to provide a true WYSIWYG editing experience on both desktop and mobile. Key features include a template gallery, the ability to save content as widgets, section dividers, and a simple form builder. The presenter demonstrates how to get started with Elementor by choosing an underlying theme, installing the plugin, and loading a template to edit.
