IBM Word Proof is a stand-alone spell checker for the IBM PC with a
list of over 125,000 standard English words. It can also find
synonyms and anagrams, and features a built-in full screen editor.
You may add your own specialized words to its list.

Word Proof 1.00 is designed for use with word processors such as
EasyWriter, PeachText, IBM Personal Editor, and IBM Professional
Editor.

Compared to other spell checkers of the time, Word Proof was
considered fast and very easy to use. It was supposedly based on the
spell checker for IBM's DisplayWriter product.
