GPTZero is a startup that offers a tool to detect whether AI, specifically ChatGPT, was used to write a piece of text. This tool is aimed at helping individuals determine the originality of the content they are reading. Plagiarism detection is crucial across various sectors, including education, media, and publishing. GPTZero was created by Princeton student Edward Tian and launched in January 2023. The company has raised $3.5 million within five months of its launch and has over 4.5 million monthly active users and 25,000 paying subscribers.
The AI-detection product offered by GPTZero is easy to use. Users can simply paste the text they want to check into the provided box, or upload a PDF or Word doc, and hit Scan. The tool will provide a result indicating whether the text was likely generated by AI and the probability of that. Users can also access an online dashboard with a free GPTZero account, which allows them to scan 40 documents per hour and check up to 10,000 words per month.
GPTZero’s paid options offer more words, files, and additional features. The Essential package costs $10 per month and includes 150,000 words per month, batch file scanning for 10 files, and access to the Chrome Extension. The Premium package costs $16 a month and offers 300,000 words, writing feedback, and plagiarism scanning. The Professional package, priced at $23 a month, includes 500,000 words, advanced data security, and single sign-on authentication.
While reviews of the GPTZero Chrome extension are mixed, the company emphasizes that its tool is a starting point for examining possible AI-written content before conducting further investigations. To address false positives, GPTZero recommends students use its Writing Report tool, which tracks a document’s creation process and edits in real-time. The company also mentions that it constantly trains its models, with at least one new release per month.

The company emphasizes that some AI-generated stories on its platform are labeled as such, while articles dealing substantively with AI are created entirely by expert editors and writers. CNET used an AI engine to assist in creating several dozen stories, but this note clarifies that the content is curated by human experts.
