Uniquely Dr.Explain captures application screens or web pages and documents them automatically
Dr.Explain is based on a unique interface analysis and screen capture system. Thanks to this system, Dr.Explain can automatically analyze an application's user interface, take screenshots of all controls and elements, and then add explanatory callouts to all images in the draft help system.
After that, all one needs to do is add descriptions to the callouts, and save the result in the HTML (online manual), CHM (help file), RTF, or PDF format.
