HelpNDoc

HelpNDoc is a help authoring tool (HAT) designed for creating various documentation formats from a single source. It allows users to write, edit, and generate documentation, including help files (CHM), web sites, PDF manuals, eBooks (ePub and Kindle formats), and printed documentation.

Key features of HelpNDoc typically include a what-you-see-is-what-you-get (WYSIWYG) editor, table of contents management, keyword indexing, conditional compilation, template-based generation, and support for multimedia elements. It is primarily used by technical writers, software developers, and documentation specialists to create professional-looking documentation for software applications, hardware products, and online services. The software aims to streamline the documentation process by enabling single-source publishing, reducing the need to create multiple versions of the same content for different output formats.
