GPTZero review: is it reliable and accurate?
GPTZero is a tool that tells us if ChatGPT wrote a text. People in schools and colleges started to worry: does zero gpt work and how accurate is gpt zero?
A while back, a student from Princeton named Edward Tian talked about a new tool named GPTZero online. This tool helps figure out if a text was written by a person or a computer.
It works a bit like some other tools we know, like Originality and TurnItIn. But GPTZero looks really closely at the text to decide if it was made by a computer or not.
So, how does GPTZero do this? Well, it checks how easy a text is to guess. If a computer can guess it easily, then it’s probably made by a computer.
What is GPTZero?
Edward Tian started GPTZero on January 3, 2023, for a school project. In just 5 months, a lot of people, 1.2 million, started using it! And now, 2.5 million people use it. Edward is a smart 22-year-old student from Princeton but the tool’s success is because of its purpose: to find out if a text is made by AI.
The tool’s name and its slogan “Humans Deserve the Truth” tell us it wants to catch AI text. It can spot writings from ChatGPT and other big AI tools. They also got $3.5 million to help grow the tool.
Is GPTZero reliable?
GPTZero is mainly for teachers. It checks student’s writings to see if they’re original. It’s made to be very accurate. But it’s not just for teachers. People who make books, edit stuff or hire writers (and students too!) can use it.
How does GPTZero work?
GPTZero is a tool that finds out if an AI wrote a piece of text. Here’s how you use it: paste your text into a box and click a button. Then, GPTZero checks the text using two things: “perplexity” and “burstiness.
GPT Zero perplexity
This is like a score for how surprising the text is. If the score is close to 0, a computer probably wrote it. If it’s closer to 100, a person probably did.
GPT Zero burstiness
This checks how often unusual words or ideas are grouped together. Machine writing is usually pretty steady but human writing jumps around more.

Testing GPTZero with different texts
GPTZero was developed with a diverse dataset of human and computer-generated texts to accurately distinguish between the two.
While GPTZero demonstrates proficiency in identifying whether short texts are computer or human-generated, its accuracy significantly improves with longer articles. My tests revealed that GPTZero often attributed short texts from GPT-4, GPT-3 and even humans to human authorship. However, with texts extended to 4,296 characters, GPTZero could detect partial AI authorship.
GPTZero scored 45 for “burstiness.” The website’s “Get GPTZero Result” button provides a final score, assessing whether the writing is human or AI-generated.
GPTZero determined the writing was likely human-generated, citing its complex sentence structures as evidence against computer authorship.
GPTZero was evaluated by NetusAI using a blog post about AI Detector Tools. This post was determined to be “likely written by a human.” This outcome is expected, given our advanced paraphrasing technology and is consistent across all AI article detection tools.
Support and Community of GPTZero
GPTZero has a big Facebook group called GPTZero Educators, with over 4,300 members. Most folks in the group work in schools and talk about how to stop students from cheating with ChatGPT. If you have any tech problems, you can message them on their contact page. They also like to hear new ideas.
Pricing
GPTZero has a free plan called GPTZero Classic. You don’t even have to sign up but it limits you to 10,000 words per month. The paid plans are mostly better at figuring out if a computer wrote something, especially for teachers. It looks like they’re really focusing on these fancier plans.

This content is not only optimized for search engines but also expertly designed to bypass initial AI detection systems. This allows the content to appear more human-written, increasing its chances of ranking well and engaging readers effectively.
FAQs
GPTZero is a tool designed to identify whether a text was written by a human or an AI, specifically ChatGPT. It was created by Edward Tian, a student from Princeton, in January 2023.
GPTZero assesses AI authorship using “perplexity” (text unpredictability) and “burstiness” (variation in sentence structure and word usage). Lower perplexity suggests AI, while human writing shows more burstiness.
While GPTZero shows proficiency in detecting AI-generated text, its accuracy improves with longer articles. Shorter texts, especially from advanced AI models like GPT-4 or GPT-3, may sometimes be attributed to human authorship.
GPTZero helps teachers ensure student originality and can also be used by authors, editors, hiring managers and students.
GPTZero offers a free plan, GPTZero Classic, for analyzing up to 5,000 characters per entry without signup.
Pros: Free, user-friendly, detects AI, supports multiple files, Chrome/Canvas compatible, light/dark modes, Word plugin.
Cons: No saved findings, paid tech key unavailable, English-only, no refunds, frequent false positives.
