Helpinator is a versatile user manual authoring and technical writing tool that allows you to generate user manuals and online documentation for all types of apps: Desktop, Web and Mobile. You can even write and publish your own technical books in Helpinator!

If you are still using CHM files for your desktop apps and suffer from compatibility problems you can use one of desktop context-sensitive help systems created by Major Mind Software as a replacement for CHM. The first one in called MajorMindHelp, it is based on HTML and apart from it's own help format it can use SimpleDocServer as a source of context-sensitive help content, or a WordPress website published from Helpinator or even a knowledge base. The other one is LiteHelp, it is a pure offline non-HTML help system, that is lightweight and portable. You can use both help systems free of charge on any number of user PCs if you own a Helpinator license.

Major Mind Software also provides SimpleDocServer (a separate product), a markdown-based webserver for in-house online documentation. You can easily generate SimpleDocServer content with Helpinator.

Helpinator allows to generate html user manuals in the form of a knowledge base. With the help of step-by-step guides you can create a comprehensive online employee handbook for your company HR department.

If you use GitHub for your project, you need at least a readme.md file for your project documentation. With Helpinator you can easily generate a readme.md, GitHub Wiki or entire GitHub pages website.

You may have heard of an excellent online documentation service called ReadTheDocs.org. It is based on reStructuredText text markup language. With Helpinator you can generate ReadTheDocs project with a single click and deploy your documentation website in minutes.

WordPress support now includes 2 online documentation themes designed for use with Helpinator and provided free of charge for owners of Helpinator licenses. Each theme is designed to be an add-on for your existing theme (e.g. they are designed to be child themes). You can also install and use free Helpinator WordPress plugin that extends WordPress API with methods for faster publishing of Helpinator content.

If your project is a web-based SaaS you can create online user manual that matches your project frontend UI library, because Helpinator allows to generate WebHelp based on Bootstrap or JQueryUI.

If you develop a mobile app you can use WebHelp based on JQuery Mobile for your project online documentation. Or you can turn this type of WebHelp into a standalone self-service Android kiosk app with Cordova.

But what if your project is a part of a larger project that already has it's own documentation toolchain? No problem, Helpinator also allows to export your project to ASCIIDoc, DITA and DocBook, so you can write your part of content in Helpinator and fit into larger project documentation based on these very popular formats.

If you plan to publish your own tech book, self-publishing is a viable choice nowadays. One of the most easy-to-use online publishing platforms is LeanPub. With Helpinator you can generate LeanPub source project and publish your book for sale online in a blink of an eye. And with WordPress support you can publish parts of your book online on your WordPress blog as a part of your book promotion.

Old popular output formats like PDF, CHM, DOCX, EPUB, MOBI, OracleHelp, JavaHelp, QtHelp are still in place.
