pojwI' (Analyzer, pronunciation: S) is a shareware program for klingonists. It has been developed by d'Armond Speers.
The latest version is available for Windows 9x/NT/2000/ME, older versions exist for MS-DOS and UNIX(1).
It is not in development anymore, the last update was on March 4, 2004.
The Klingon to English translation is in a separate window, so you only have to have a comparatively small window open, making it useful to translate texts while reading something else. Mistakes, for example wrong order of suffixes, are marked.
The translation feels surprisingly natural: Dalo'be'nISqu' becomes "you really need to not use him/her/it/them".

The program is shareware and should be purchased for about 20 US Dollar after having tried it.
