detecting AI
How can you know if the piece of writing submitted by a student is not their original work? Well, essentially, your teacher's gut feeling tells you. There might be expressions that no student would ever use. Or perhaps the text is off-topic, dealing with the general theme, but not making complete sense or addressing the points given in the instructions. That's the time to check whether the text has been copied and pasted from somewhere else, or written by an AI bot.
Ask chatGPT itself: did you write this?
https://gptzero.me/- While GPTzero may not be able to tell you that the text has definitely been written by AI, it does analyse the way the text has been written and can tell you about the likelihood that the text might be AI-written (or highlight sentences which are likely to have been written by a bot):
https://www.zerogpt.com/: works in a very similar way to gptzero.
https://www.thomas.io/detect-gpt (Chrome extension)
https://contentatscale.ai/ai-content-detector/ It uses advanced natural language processing models to detect AI-generated content. Simply type your text or paste it into the text area and hit Check for AI Content. Within seconds you get a human content score that predicts the possibility of your content being fully human-written, partially human-written, or fully AI-generated.
Draftback (Google Chrome extension): this extension shows how the text was typed (or pasted) into a Google document.
The first video shows the process of writing a student's original work (or, at least, you can see how they typed the words, including typos).
The second video, however, illustrates what happens when text is pasted into the document:
*Bonus tip: do not underestimate good old Google Translate. I've had students confess they had simply written the text in Spanish and then run it through Google Translate. Banking on that admission, I have sometimes done the opposite process: I've asked Google Translate to translate a submitted piece of writing into Spanish. That helped me understand many of the inexplicable sentences or non-sensical punctuation marks.
