RoboHelp is a help authoring tool used to create online help manuals in formats like HTML, PDF, and Microsoft Help. It allows importing and editing of content, provides features for adding topics, graphics, links, tables of contents and indexes, and can output to multiple formats from a single project. The main difference between RoboHelp and Webworks Publisher is that RoboHelp provides direct editing of source files while Webworks Publisher compiles files generated from Adobe Framemaker.
