Grammar checker software

<p>Hello,</p> <p>In French (my mother language), there is a software called <a href="http://www.druide.com/antidote.html" rel="nofollow">Antidote</a> which is really good for grammar checking. What is even better, is that it works on Linux (last version even on 64bit).</p> <p>I'm looking for an equivalent in English. I found <a href="http://www.whitesmoke.com/" rel="nofollow">WhiteSmoke</a> but it's only for Windows and OsX.</p> <p>Is there an equivalent for Linux ?</p> <p>Thank you</p>
