Students write applications that discover content from ChatGPT.
“There is a lot of excitement and enthusiasm at ChatGPT. But like any new technology, it must be used responsibly,” said Tian, a senior lecturer at Princeton University in Canada. SCMP above the motivation for the birth of GPTZero.

With the goal “People have the right to know the truth”, this app is aimed at educational developers or those who need to evaluate whether the text they are reading was written by a human or by an artificial intelligence. GPTZero attracted such attention that not long after its launch in early January, the app servers crashed, forcing Tian to purchase additional Streamlit online storage. To date, the app has received more than a hundred thousand downloads.
Launched by OpenAI in late November 2022, ChatGPT has already attracted over a million users worldwide in less than a week. With the ability to react naturally and quickly, this artificial intelligence is increasingly being used by students for homework and essays.
Tian considers ChatGPT a “Pandora’s box for social media technology”. “While this is a great innovation, it has many downsides,” he said.
The 22-year-old student said that GPTZero uses two variables to determine whether the text entered was written by a bot or a human: complexity and simplicity. Difficulty is a measure of the randomness in a text. If the corpus is unknown, it means it “confused” the AI and most likely was written by someone. If the text is known and already exists in the database, the system recognizes that it was generated by AI.
According to Tian, complexity is an independent and “imperfect” measure, so an extra step is needed to compare semantic sentence variants. “People tend to write with many variations of sentences, such as long sentences, short sentences, active sentences alongside passive sentences. Meanwhile, texts written by AI are more consistent,” explains Tian.
Tian was born in Tokyo but lives mainly in China and Canada. He attended Princeton University and worked for the school newspaper. Princeton Daily. Having grown up in an evolving science and technology environment, he is interested in the intersection of computer science and journalism and how technology can be used to enhance multimedia storytelling.
“Writing and autowriting are still important skills despite the passage of time, so writers and man-made works are always valuable. AI can “write” better, but people still love it. I love works written by people. Tian said.
