Nisus Writer, originally Nisus, is a
word processing program for the
Apple Macintosh.The program is valued by its users — especially serious users like book authors — for its reliability and unique features. It has been criticized because of its rather unorthodox interpretation of Apple's user interface guidelines.Nisus Writer was the first word processor for Macintosh — long before
Unicode was introduced — which was able to handle multiple type systems within one document, e.g.
Arabic,
Hebrew,
Japanese, etc., thanks to
WorldScript. Therefore Nisus Writer was an indispensable tool for people who had to integrate passages written in non-Roman script into a regular document, for instance theologians and archaeologists. Other distinguishing features of the program were non-contiguous text selection, multiple clipboards, voice recording, and so on.
