I've been using LanguageTool for a few weeks now and have found it to be incredibly helpful. My emails, Tweets, and everything have been significantly improved thanks to its unintrusive and intuitive UI. Definitely recommend!

Хорошее дополнение, очень помогает.

At last a spell checker that works.
