Spell Catcher X is a powerful, all-in-one spell checking and writing software solution—a program that’s so much more than a spelling checker, its name only hints at its capabilities. With Spell Catcher, you’ll write better and faster—in virtually any application. Use it to spell check e-mails, letters or documents, instant messages, and more! Spell Catcher can watch for errors as you type, and automatically fix common typos. Shorthand Glossaries let you define your own abbreviations for repetitive phrases—even thousands of characters long! Use the dictionary or thesaurus to look up a word you’ve just typed to check its meaning or search for a more precise alternative.
