GPTZero seems to work pretty well. In my initial run with the app, I plugged in some text from a recent conversation with ChatGPT and, within seconds, it accurately deduced that the copy was “machine generated.” Next, I plugged in some writing from a recent blog of mine, and, again, it quickly figured out that it was written by a human. The more text you plug into the program, the better the results seem to be—so it helps if you add at least several paragraphs of copy for an accurate readout.
