When writing for my WordPress blog I have used the WordPress plug-in "After the Deadline". As I am not native English, this helps me correct spelling and grammar errors.
Recently
the same tool is released as an extension for Chrome and Firefox. Using this extension it is possible to use the tool with any form on webpage when it is viewed with Chrome or Firefox.
For example, I used it with the tip and article submission form on The Code Project. The best thing is that it is free for personal use :-D.
The
homepage of the tool shows more information. Here are
the Chrome extension and
the Firefox extension.
