What is CHMAddIn?

CHMAddIn is a plugin for Microsoft Word that allows you to convert Microsoft Word documents to HTML Help (CHM) files. It is designed for use by authors or developers who create Help for software programs.

Why CHMAddIn?

No doubt that Microsoft Word is the most popular and powerful text processor. Microsoft Word is the de-facto standard editor for creating technical documentation in many companies - it's fast, stable and user-friendly. Help documents created with Microsoft Word can be easily converted to another popular formats - PDF, Open Office format and so on. But what about HTML Help? There are a lot of programs that can create Microsoft HTML help files but very few ones that are able to generate HTML Help directly from Microsoft Word document. CHMAddIn does it and does it perfectly.
