For an online project I'm working on, I am looking for a open source grammar checker. I have searched Google, with some good results (http://www.link.cs.cmu.edu/link/, etc), but I am wondering what all of you think about this topic.
I need this to be able to be used online, versus desktop based, but this is the only real specification I have. If it has a built-in spell checker, that would be a plus, but I can always use another project for that purpose.
Thanks for any help.
LanguageTool should fit the bill:
try polishmywriting.com (now afterthedeadline.com)
I think the developer's details are here: http://news.ycombinator.com/user?id=raffi here's an ASK HN post from raffi: http://news.ycombinator.com/item?id=286162
UPDATE: you can get an API Key (i.e. for Wordpress): http://www.afterthedeadline.com/download.slp?platform=Wordpress
Have you taken a look at the Xinha project? I believe that has spell check and possibly grammar check.
Several wysiwyg editors have support for spell checking: feckeditor, htmlarea, tinymce.
I think most of them uses aspell dictionaries.
