Spell Catcher 8 for Mac

From Rainmaker Research:

Spell Catcher 8 is a spelling and typing correction application that works with the operating system and allows you to correct spelling, punctuation, and create macros in virtually every application. Spell Catcher works interactively or in batch correction mode, even if your application has its own built-in spell checking feature. The new version is a free update for previous owners of Spell Catcher 8, and offers a number of feature enhancements, bug-fixes, and anew dictionary-converting application, the Spell Catcher Converter. This application can convert user-defined dictionaries into the Spell Catcher 8 format automatically, without the user having to manually re-enter special entries.
