WordPerfect (WP) is a word processing application, now owned by Corel. At the height of its popularity in the 1980s and early 1990s, it was the market leader of word processors, displacing the prior market leader WordStar.

WordStar is a discontinued word processor application for microcomputers. It was published by MicroPro International and originally written for the CP/M-80 operating system (OS), with later editions added for MS-DOS and other 16-bit PC OSes. Rob Barnaby was the sole author of the early versions of the program.

ChiWriter was a scientific word processor for MS-DOS, created by Cay Horstmann and released commercially in 1986.
