Abstract: Systems, methods and products for assisting an author in targeting content to a desired audience. In one embodiment, a content readability plug-in is installed in an authoring tool. The author identifies a desired level of readability, type of communication or audience, from which the plug-in determines a desired level of readability. As the author creates content using the authoring tool, the plug-in examines the content and assesses its readability using readability indexing techniques embodied in a readability index library. The plug-in then provides feedback to the author which indicates the readability, and may provide suggestions for improving the readability of the content. The plug-in may provide feedback in real time as the content is being generated, or it may examine and assess a completed body of content. The author can then revise the content based on the feedback to achieve a readability level suited to the target audience.
