'jQuery spell check' is a jQuery plugin that adds spellchecking functionality to web-apps using pure jQuery Code. It features a live demo and free development licenses for PHP, ASP, ASP.Net, and Java developers.

With jQuery spell check, users can enjoy a hassle-free experience, as the software does all of the spell checking itself using AJAX behind the scenes. This means that users do not need to download huge dictionary files or send their data across the internet for remote processing on a third-party server. As such, jQuery spell-check is perfect for use in an intranet or secure login environment.
One significant advantage of this plugin is that it can also be used in 'abstract' as a behind-the-scenes spell-checker for form-processing, online word games, or even for spellchecking rich/wysiwyg HTML Editors, such as TinyMCE and CKEditor.
Another advantage of jQuery spell check is that users can 'Add' or 'Learn' words just like in Microsoft Word, and these words are stored locally and affect only one user. For enhanced experiences, developers can configure the software to cause those words to be added to a central repository for all users to share, which is especially popular on Medical and Engineering intranet projects.
The installation process is also incredibly easy, and you can install it on Windows, Linux, and OSX by uploading one folder into your website project. To get started with this powerful software, simply read the jQuery SpellCheck tutorial at javascript-spellcheck.com. There, you'll be able to see an example with source code, download the plug-in for your own project, and check out the full guide to make the most of jQuery spell check.
