Two AM Software has released Dictionary Cleaner, a free utility that helps you edit your custom spelling dictionary.
Mac OS X lets you easily create a custom dictionary to spell words you commonly use that aren’t built in to the dictionary included with the operating system. But it doesn’t provide an easy way for you to edit that dictionary once you’ve added words to it.
The solution is Dictionary Cleaner, a utility that installs in the Mac’s System Preferences. The software lets you view, add and edit words. It has support for English, French, German, Spanish, Japanese, Chinese (Simplified and Traditional), Portuguese, Polish and Finnish.
