Introduction

ChatGPT is undoubtedly the top AI model available today, with over 300 million weekly active users. Just about everyone uses this tool to write, especially when it comes to school essays. 

As tools like ChatGPT become more common, so does the use of AI detectors. GPTZero is a great example of such a detector, with over 2.5 million users around the world. The question is, is there anything better than GPTZero?

Since there’s no shortage of new AI tools being launched every day, you may expect the same variety in AI detection, too. Today, we’ll test the effectiveness of GPTZero against competitors to answer your question.

GPTZero Benchmarked Against ChatGPT

ChatGPT only gets more advanced by the day, with most experts being unable to tell the difference between human-written and AI-written text. The good news, GPTZero is advancing at the same rate, too. That was proven in a recent study by GPTZero.

In this test, they compared 250 human-written texts to 250 generated by a clever AI designed to sound human. Not only did the AI-written version pass undetected by human reviewers, but they even said it sounded “more human.” 

That’s because it contained personal anecdotes and first-person perspectives. Plus, the human-written text had phrases like “In conclusion,” which AI tools tend to use often. Even then, GPTZero was able to detect the AI-written text with 100% probability!

That’s because GPTZero’s detection system relies on two metrics: perplexity and burstiness. The first measures the text’s predictability – lower means more AI-generated. Meanwhile, burstiness measures how variable the text is, which is higher in human text. Plus, GPTZero detects AI-written work sentence-by-sentence instead of analyzing the text as a whole.

Potential Competitors to GPTZero

To find out if there’s anything better than GPTZero, we need to compare it with its top competitors. Let’s see how these three tools perform against GPTZero.

Originality AI

Originality AI combines AI detection with plagiarism checking and has an accuracy rate of 80%, compared to GPTZero’s 98.6%. It also has a false positive rate of 0.05%, while GPTZero’s is 0%. However, unlike the latter, Originality AI supports multiple languages and quick file uploads.

This tool also has a Turbo version, in which the accuracy rate actually drops by 0.2%. This version also has a higher false positive rate (0.37%) and recall (97.2%).

Copyleaks

Copyleaks is the easiest to use when it comes to AI detectors. The interface is pretty simple, and it only takes a few seconds to show your results. However, it does lack the accuracy offered by GPTZero, standing at only 90%. 

However, in our experience, its actual accuracy rate would be even lower. Another thing worth considering is that it only displays its results as “human-written” or “AI-written,” not an accurate percentage.

ZeroGPT

ZeroGPT, using proprietary DeepAnalyse™ technology, also has a very user-friendly interface and a free plan. Plus, compared to GPTZero’s 5,000-word capacity, this tool can analyze up to 15,000 characters per scan. Its false positive rate is also fairly low, but its accuracy rate stands at only 85%.

GPTZero Beyond Benchmarks

Benchmarks can tell you a lot about the accuracy of an AI detector, but they don’t tell you everything.  Sure, we need to know how well an LLM performs on specific tasks. But what about ease of use? Is it a pain to actually use the model?

Luckily, that’s not the case with GPTZero, which has a very clean and simple interface. Plus, it has an Origin Chrome extension to make integration even simpler. And GPTZero isn’t just an AI detector – it also doubles as a plagiarism checker and source finder.

Conclusion

To wrap it up, there’s nothing better than GPTZero, at least not when it comes to accuracy. The tool has a near-perfect accuracy rate, along with 0% false positives and 97.2% recall. 

However, what it offers in accuracy, it lacks in versatility. Many of GPTZero’s competitors have a higher text capacity and many other built-in tools to improve the user experience. But if you’re a professor trying to make sure your students aren’t using ChatGPT to write their papers, this AI detector is your best bet.

What’s more important to you in an AI detector—unmatched accuracy like GPTZero offers, or greater versatility with additional features?
