GPTZero AI Content Detector Review 2024: Is GPTZero Reliable & Accurate?
Ever wondered if the content you're reading was written by a human or generated by an AI tool like ChatGPT? As someone who regularly tests AI tools, and more, I've found myself asking this question more frequently.
To find out, I decided to dive deep into GPTZero, a AI content detection tool designed specifically for this purpose. With my background in testing various AI detectors like Turnitin , Scribbr , Copyleaks AI Detector , I ran several experiments to see just how accurate and reliable GPTZero is when it comes to identifying AI-generated text.
In this review, we'll explore GPTZero's accuracy, its key features, and whether it is a reliable solution for detecting AI content.

What is GPTZero?
GPTZero is an AI detection tool developed by Princeton University student Edward Tian and launched in January 2023. It is designed to identify text generated by large language models such as ChatGPT , GPT-4 , Google Gemini , LLaMA , and more. By distinguishing between human-written and AI-generated content, GPTZero provides a reliable solution for individuals concerned with maintaining academic and professional integrity .
My Verdict: Is GPTZero AI Detector Reliable?
GPTZero is a free and relatively reliable AI content detection tool, but there is still room for improvement, especially when it comes to accuracy. After conducting 3 different text tests, I found that GPTZero's results were mostly correct and acceptable, with only slight inaccuracies. However, based on the feedback I gathered from Reddit users, many have expressed concerns about its accuracy and false positives.
Overall, GPTZero is still a well-performing AI detection tool, especially as it continues to receive real-time updates, and its interface is clear and user-friendly. GPTZero has the potential to become an even more robust solution for AI content detection in the future.
For those looking to bypass AI detection tools like GPTZero, I recommend Tenorshare AI Bypass. After conducting the test below, I found that this tool can effectively bypass AI detection like GPTZero, getting a high human score.
GPTZero Review on Reddit
Many users have praised GPTZero for its ability to identify AI-generated content, particularly in academic settings where integrity is key. However, some have reported instances where human-written content was incorrectly flagged, leading to concerns about over-reliance on the tool.
I gathered real user feedback from Reddit , where one user was frustrated because adding a simple double space changed the AI detector's result from 99% AI to 99% human.
Similarly, the other user was complaining about the inaccuracy of GPTZero AI detector . GPTZero flagged this user's text as AI-generated. However, after removing or changing just a few words, the detector marked the entire text as human-written.
In general, users appreciate its speed and ease of use but advise combining it with human oversight to avoid potential false flags.

How Does GPTZero Work?
GPTZero works by analyzing the statistical properties of a text. It primarily focuses on two metrics:
- Perplexity: This measures how surprised a language model would be by the text. A higher perplexity suggests a more unusual or complex text, which could be indicative of human authorship.
- Burstiness: This measures the variation in complexity within the text. A higher burstiness indicates more frequent shifts between simple and complex language, which is also often associated with human-written content.
By comparing the perplexity and burstiness of the input text to a database of known AI-generated text, GPTZero can identify patterns that are characteristic of machine-generated content.
Testing GPTZero AI Detection Accuracy
To test GPTZero's accuracy, I conducted tests using a range of different text samples. These included 100% human-written content , fully AI-generated text , and an additional challenge— AI-generated text that had been paraphrased using Quillbot's Paraphrasing tool. This setup allowed me to explore how well GPTZero can differentiate between human and AI writing, as well as whether it can detect AI content that has been rewritten by another tool. Let's dive into the tests and see how GPTZero performs in these various scenarios!
Test 1: Can GPTZero Detect AI Content Generated by ChatGPT?
Firstly, I asked ChatGPT to generate an article on climate change, with over 500 words. This is 100% AI-generated content. Can GPTZero detect it? Here is the result of the first test:
After scanning the text, GPTZero reported a "91% Probability AI generated" result. As expected, GPTZero was able to detect the AI content, but it did not give a 100% AI-generated result. There's a slight margin of error , around 9%.
Test 2: Can GPTZero Detect Human-Written Content?
This is 100% human-written text, and GPTZero detected only a 5% probability of it being AI-generated. I'm satisfied with this result, as the accuracy is very high .
Test 3: Can GPTZero Detect Quillbot's Paraphraser?
Let's up the challenge! I'm very curious to see if GPTZero can detect text that was fully AI-generated and then rewritten by Quillbot.
Finally, for the paraphrased AI text, GPTZero gave a result of "76% probability AI generated" and "24% human-written." I find this result acceptable . While it's not 100% accurate, it did a fairly good job, as it recognized that most of the text was likely AI-generated.
How to Bypass GPTZero: Try Tenorshare AI Bypass
Based on the tests conducted above, GPTZero AI Content Detector performs quite well overall. However, if you're looking for a tool to bypass this AI detector, you can try the free online humanizing tool - Tenorshare AI Bypass.
Is Tenorshare AI Bypass Reliable?
Seeing is believing, so let's put it to the test! I took a climate change article generated by ChatGPT and ran it through Tenorshare AI Bypass to see if it can successfully bypass GPTZero's detection. Below is the output from Tenorshare AI Bypass:
Next, I submitted the AI text rewritten by Tenorshare AI Bypass into GPTZero for scanning. The result from GPTZero was: "3% Probability AI generated." This is an excellent score, meaning that the humanized rewriting from Tenorshare AI Bypass can successfully bypass the GPTZero detector.
