There are concerns about classroom use of AI generated essays. See for example: “A Toolkit for Addressing AI Plagiarism in the Classroom” [Archived].
AIWritingCheck.org was created by education technology nonprofits Quill.org and CommonLit.org to assist teachers in determining whether writing was produced by humans or artificial intelligence, the organizations claimed in a news release.
Another tool GPTZero.me says that “Humans Deserve the Truth” and also offers to check if a text was generated by human(s) or AI.
Yet another was already prepared for the previous version of GPT: https://openai-openai-detector.hf.space
My test so far is very inconclusive, and it seems probably that at some point it will not be possible to distinguish AI or human-generated text in a lot of cases.
Interestingly Quill has another web page that helps to paraphrase text: quillbot.com… In fact the paragraph above about AIWritingCheck.org is paraphrased from the first paragraph of this article: Artificial Intelligence – New Free Tool for Teachers Can Detect ChatGPT-Generated Student Work, Nonprofit Creators Say, By Kristal Kuykendall 01/31/23 [Archived].
