GoogieSpell is an Open Source AJAX-Based spell checker offering a Gmail like spell checker solution for your own application. The project is written in Javascript only and is using Google and Aspell for the spelling feature. It's pretty fast and also available as online service Orangoo spell check, I just missed the ignore feature since the speller don't always provide good suggestion. To use it download the latest GoogieSpell 3.1, the download package include the javascripts, images and demo code. Released under a GPL license.
