The plugin allows users to embed interactive webfont specimens on their site via shortcodes. Users can preview, type with, and switch the webfonts in a preview, as well as use other interface options to manipulate the font sample.
The projects was initially financed through an Indiegogo campaign and is now maintained by Underscore as an open source project.
