Edit Minion is a resource for cleaning up writing in terms of looking for repeated words, phrases, and even things that may come off as cliche. For example, I asked Edit Minion to help clean up the first chapter of my novel, Facades, and received this screenshot.
(Yes, "toilet" made it onto the list.)
As needed, the user can ask Edit Minion to look for certain things such as possible homonym issues, passive voice, adverbs, weak words, etc. An example of what that looks like in my own writing is below.
Personally, I find the color coding really helpful, and I'm definitely going to be using Edit Minion for final cleaning up before publication! I definitely recommend it. It's a wonderful resource. Nothing is saved on the website, so it's safe for use without copyright infringement worries!
And, as proof that I have improved as a writer, I dug out some writing from when I was 13 and stuck it into Edit Minion. Excuse me while I cringe.
Happy writing, everyone!
