CalliGrapher, one of the most popular Pocket PC handwriting recognition applications on the market, analyzes pen strokes written in any application window or in the designated Write Pad area, then converts those pen strokes into text and sends the recognized text to the target application. Employing advanced fuzzy logic and neural net techniques, CalliGrapher recognizes arbitrary alphanumeric strings as well as words contained in its integrated dictionary.

CalliGrapher 8.0 supports the Microsoft Windows Mobile 5.0 software platform. In addition to the classic CalliGrapher "Write Anywhere" input method, which allows users to enter handwritten information anywhere on the screen, CalliGrapher 8.0 introduces a new soft input panel called Write Pad. Write Pad is a specified area at the bottom of the screen where users can enter handwritten information that is instantly recognized and converted to the digital text. The text can be easily sent to the desired application.

In addition to handwriting recognition, CalliGrapher offers PenCommander, an easy-to-use PC navigation tool, and a "Quick Correct" window for fast correction as the user writes. CalliGrapher also offers language pack offerings for 11 foreign languages and Medical Pack, a 130,000-word professional-strength English language medical dictionary.
