I’ve been playing around with a few of these, and it seems there are some plugins that you can actually use for free. I’m sure there is an ethics clause somewhere in the code that keeps me from using them for unethical purposes, but they appear to be useful enough that you don’t have to pay for them.
The first one is called ‘Find Words’. It searches through your document looking for all instances of words or phrases. For example : My client has a legal interest in this case? If you search by the word “legal”, Find Words will tell you where those other two lines should be moved so as not to violate an ethical rule or statute. It does it very quickly too, which makes it even more powerful! Another way to do this would be WordFence instead .
