Brizy Pro is a purely visual page builder for WordPress. To create your page, you first need to add a block. You can use an empty block, or you can choose from pre-made section blocks. The "unique interface" part is what happens when you start adding elements. Instead of having a sidebar or popup where you customize/style the element, pretty much everything happens inside (including typing). The result is a very fast way to create pages.

This new page builder is still young, but already has a huge set of blocks, templates and powerful functionality.
