>>Does your Grammar Slammer with Checkers work with Windows XP?
Yes. It works with all versions of Windows from 95 up. As of this date that includes Windows 7.
>>How does this program compare to checkers in Word or Grammatik?
All use slightly different patterns. The grammar checker in Grammar Slammer gives the user many easy options. Probably the best thing for you to do is download a trial copy from our download site at https://www.englishplus.com/pub/ and see how you like it.
Be sure to read the file that comes with it, “What to Expect from a Grammar Checker.” This will give you an idea of what anyone’s grammar program can and cannot do. You can also read this online at https://englishplus.com/news/readthis.htm.
