- I fed this tool one of my old essays that was written before AI writing tools were available and it reported 79% AI written. I only used this tool to test its accuracy and I'm baffled. I hope professors are not using this as their plagiarism ultimatum. I good professor or writing auditor will examine an individual's writing patterns over different pieces. All this tool does is tell you that your writing sounds like AI to scare you into buying their other features that just scramble your own writing style.
