I'm looking for a software that could search through the text of a EULA or other contract for suspicious clauses that you might take issue with.
Does such a software exist? and if it does, Where can I get it?
I think you are talking about EULAlyzer. It was done by JavaCoolSoftware up to some time ago, now BrightFort LLC. It has some analysis tools that helps you to identify weird clauses about third parties, data collection, advertising, etc.
I have used it and didn't gave me trouble finding stuff in lengthy text nor unexpected behaviors. It comes as freeware with advanced/premium characteristics but the basic covers you for legalese analysis.
Take seriously this note:
Note: This program does not provide legal advice. It can only highlight information that you may want to consider before making your own decision whether to agree to a license agreement or not. You should always consult a lawyer (or other authorized individual) for advice on legal issues.
It only works in Windows up to 7 officially, I haven't tested 8. Doesn't have Linux/Mac counter parts.
Note: it only expects EULA's, if you try another legal document you may not get the desired results.
