A senior pupil at Princeton University has killed the dreams of thousands of students hoping to write their essays with the AI tool ChatGPT.
22-year-old computer science major and journalism minor Edward Tia said he spent his winter holiday creating the GPTZero app to combat increasing instances of plagiarism.
The GPTZero app can determine whether an essay was created using ChatGPT or written by a human.
The free AI writing tool has caused a stir with its impressive writing skills and was recently restricted by New York City school officials on school devices and networks to prevent students from cheating.
GPTZero uses two indicators to determine the likelihood that AI wrote a text.
The first is the “perplexity” of the text, which determines the probability of specific words being suggested by a bot. At the same time, “burstiness” inspects the spikes in each sentence and evaluates how randomly the text is written.
Tian’s app has been praised by educators and those wanting to prevent plagiarism in an increasingly digitalized world.
