Online Grammar Checker for TeX files

This is a simple Grammar Checker for TeX files. Just paste your text into the text box and press Go. This checker has some ability to look inside math text to determine whether it starts with a vowel. For example try "`A $\frac{n}{2}$'-dimensional space is an error but `a fractal' is fine". If you also want output from the 3rd party LanguageTool (LT) Checker appended, check the box; LT errors that are less relevant to TeX will be filtered out.
