Help+Manual eWriter Help is available for Windows and MacOS. Use ePUB, PDF or Word RTF to target other platforms.  


This exclusive Help+Manual format packages WebHelp with its full table of contents and user interface into a single file. On Windows 10 users will be prompted to install the Windows Store eViewer app for eWriter when they open a file with the .ewriter extension, if they don't already have the viewer. A free installer for the standard Windows eViewer app is available from our eWriter page for users on earlier versions of Windows.

EWriter uses Windows' own HTML rendering engine to display the content, with full support for CSS3, HTML5 and JavaScript. The eWriter files are neutral, digitally compressed files that can be distributed without signatures by download or as email attachments.

The better alternative to CHM on Windows

eWriter Help files are an attractive alternative to the obsolete CHM format for documenting software applications on Windows machines. The eWriter format combines the benefits of CHM and WebHelp and eliminates many disadvantages of both. It also allows you to execute operations in your application with hyperlinks for the creation of interactive help tutorials.

A modern integrated help format for MacOS

With the exception of the very old Apple Help/Help Viewer format that most Mac apps no longer use, there is not really an integrated help format like CHM for the Apple platform. eViewer provides one.

Layout and functionality with WebHelp skins

You can use WebHelp skins for eWriter to get all the layout and formatting options available in WebHelp, including integrated search and a keyword index. At the same time, it is a compact single file like a CHM and supports context help calls from applications. Unlike CHM files, it can be accessed on networks, and unlike WebHelp, repeated application calls to the same eWriter Help file all open in the same window. It is stored in a single, compact binary file.
