The Las Vegas Writers Group Message Board › Punctuation/Grammer Checkers
Las Vegas, NV
If you're using LibreOffice (formerly OpenOffice) like me, you probably don't have a punctuation/grammar checker out of the box. Here's some handy tools to fill that need:
Language Tool: This is a plugin for LibreOffice. It's comparable to the grammar check (green underlines) in MS Word.
Des found the next two.
Gregory's Punctuation Checker: Past your text in and it'll find punctuation/grammar errors. It's not perfect though so research everything it tells you before you apply it.
Grammar Check Me: Same as above, but also includes articles on writing.
