pearDict

pearDict is a little tool that makes access to various online dictionaries very convenient, as it's fully integrated into your workflow. Simply select a word in any Cocoa-based application, choose the 'Look Up on Web Dictionary' entry from the Services menu and pearDict will find the word for you. Or how about that - simply move the cursor over a word and press a keyboard shortcut - pearDict will magically look up the word online. The same also works for current selections or text-cursor placements - of course with customizable keyboard shortcuts. This even works for none-service aware applications. Of course, you can also manually look up words by entering them directly into pearDict's search field. If the information provided by pearDict is not good enough, you are only a mouse click away from the fully-featured dictionary Web page.

pearDict is provided for free in the hopes that it makes communication between people of different cultures and languages easier.
