Productive grammar and spelling checker for the web. I'm a native English speaker, and Linguix still helps me improve my English. In addition to the spelling and grammar checking, I like Linguix's snippet feature to help me speed up my workflow by saving things I frequently type. I also like the user dictionary -- unlike the user dictionary in Android OS, it's easy to remove words that shouldn't be there. Now I'm waiting for future releases of Linguix. Hopefully they will support multiple languages!
