HelpSmith is a help authoring tool that you can use to create HTML Help (CHM), Web Help, Printed Manuals, Adobe PDF, MS Word documents, and ePub eBooks from a single source. HelpSmith includes a rich feature set combined with an easy-to-use user interface with a slight learning curve. Among the advanced features available in HelpSmith is the built-in Image Tool that significantly simplifies the way of writing documentation for user interfaces. For example, you can easily capture screenshots, create various annotations for images (balloons, arrows, ellipses, text labels, etc.), add clickable hotspots, and also use control annotations for UI elements that can be exported into the help topic where you can provide a detailed description for each control.
