Helptrix consists of two separate applications:

In fact you are using Helptrix Author to write help or manual in one language you have chosen (main book language). As soon as help or manual is done, it could be translated to additional languages using Helptrix Translator.

Helptrix is based on single-sourcing, which means, that you write content of help or manual only once, and then publish it in several different outputs (HTML Help, PDF, HTML) from the same source. This features helps you to keep all different formats of your help or manual in consistent state.

Helptrix Author allows writer fully focus on content instead of formatting, because you can use only several pre-defined elements in your topics. Let's assume a note in the text: you don't to have remember how you have formatted note before (font, indentation, background color) - in this editor you just insert note element, and you are sure, that all notes will look exactly same way in every output.Of course you can adjust output appearance, when creating it. This approach preserves united look of your help systems and manuals.
