The spelling checker is installed by default in Open Office, but what’s missing is grammar checker. For those who are weak in English, grammar checker is really a handy tool which it exist in Microsoft office version 97, or even earlier but not in Open Office.
Well, recently I discover a language tool plugin for open office written in java which does grammar checking. You can check out this language tool at here, installation is simple and straight forward, I have tried it on open office 2.3 and it works well for me.
Well I tried to make some silly grammar mistakes and try out this language tool, but it fails to detect the mistakes. It seems that this Language Tool still have room to improve, you can help to improves it by helping them writing the rules in XML, check out their development page here.
