I looked for information on gradework, and couldn’t find anything. From your description, it sounds like you presume the software is accurate. I’d expect there to be peer reviewed studies about its error rate, a description of how it works, limitations, etc. For instance, if you ask for a one sentence factual response to a question, there’s no way it will be able to distinguish LLM from human. I’m sure it has other limitations. I met someone that built one of the better packages in the “don’t copy your answers from google” space a while back. He routinely gets pleas for help from people his software has falsely accused of plagiarism (the tool is open source and popular and maintained by others). He generally sends strongly worded letters to educators explaining the limitations of the tool, why it’s probably wrong in this case, and that says he will happily testify against them in court as an expert witness. I imagine the commercial vendors are less transparent, but not more accurate.
