KnowHow is a unique knowledge manager that interacts with your PC and allows you to add notes and information to any program, folder or window. Instead of keeping separate notes, you can simply click the tray icon and add a note or comment that will be associated with the currently open program, document or window and can be recalled at any time you use the program. The tray icon tracks your PC usage and will automatically inform you if any KnowHow is available for the currently active window. KnowHow can also be used to add notes to websites, individual documents, email contacts and more.
