GPTZero: AI Content Detection Tool Explained

by | AI

AI is everywhere these days, from our smartphones to our cars and even in the articles we read online. But here’s the kicker: sometimes, it’s hard to tell if the text you’re reading was penned by a human or whipped up by an AI. That’s where GPTZero comes into play!

GPTZero is an AI content detection tool designed to predict if a piece of text has been written by a large language model like ChatGPT. It’s trained on a vast dataset of both human and AI-created text to provide predictions at the sentence, paragraph, and document levels.

In this article, we’re going to dive into the nitty-gritty of GPTZero and explore how it’s shaping the future of AI technology.

Let’s do this!

What is GPT Zero?


GPTZero is an AI detector created to detect text generated by AI models like ChatGPT, the artificial intelligence writing tool that has caused ripples in the education system due to its capability to produce seemingly human-written text in response to prompts.

Developed by Edward Tian, a 22-year-old senior at Princeton University, GPTZero serves as a reliable way to ensure the authenticity of written content in an age where AI-made text is becoming increasingly indistinguishable from human-written text.

How Does GPTZero Work?

So, you’re probably wondering, how does GPTZero tell the difference between human and AI text? Well, let’s pull back the curtain and take a peek at the magic behind the scenes.

At its core, GPTZero is an AI model that’s been trained to play detective. It sifts through text — be it a sentence, a paragraph, or an entire document — and predicts if it was written by a human or an AI. It’s like a bloodhound, sniffing out AI content from a sea of words.

GPTZero is trained on a massive dataset of human-written and AI text that has never been published on the internet. It’s been taught to recognize the subtle differences in style, structure, and other linguistic features that distinguish human writing from AI content.

When GPTZero analyzes a piece of text, it’s not just looking at the words. It’s examining the sentence structure, the flow of ideas, the use of vocabulary, and a whole lot more to pick up on the telltale signs of AI content masquerading as human-like text.

Highlighted text that GPTzero thinks was made by AI

GPTZero provides a score, known as ‘completely_generated_prob,’ which indicates the probability that the entire document was AI-written text. The score is a sliding scale that gives you a nuanced understanding of the extent to which AI may have been involved in generating the text.

For situations where the content is a mix of human and AI content, GPTZero can provide sentence-level classifications, highlighting specific sentences that it believes were written by AI like in the above image.

And it’s not just limited to one type of AI model. GPTZero is a versatile tool, and it can detect content generated by a range of AI tools, including the likes of ChatGPT, GPT-3, GPT-2, LLaMA, and other AI models. It’s like having a universal translator for AI language models!

How Much Does GPTZero Cost?

GPTZero pricing plan

GPTZero has three plans, and we’re going to go over each one in this section.

1. Free Plan

The free plan is great for hobbyists or content creators who occasionally need to check content for AI content. Its features include:

  • 5,000 character limit per document
  • 3 file limit for batch uploads

2. Educator Plan

The educator is, as the name implies, designed for educators. It costs $9.99 per month and includes:

  • 50,000 character limit per document
  • Unlimited batch uploads
  • Check up to 1 million words per month
  • Access to a more fine-tuned detection model for education

3. Pro Plan

The pro plan is for super users. It costs $19.99 per month and includes:

  • 50,000 character limit per document
  • Unlimited batch uploads
  • Check up to 2 million words per month
  • Access to GPTZero’s premium AI detection model with high limits

How Much Does the GPTZero API Cost?

GPTZero API costs

Businesses and developers who want to access the GPTZero API for custom solutions have to pay for a separate subscription that starts from $14.99 per month for a run up to 0.5 million words per month.

The cost is based on the number of words you expect to run up in a month, which can be increased to up to 5 million words per month at $99.99. Developers and businesses who need a higher limit have to contact GPTZero for a quote.

Applications of GPTZero

Now that we’ve got a handle on what GPTZero is and how it works, let’s talk about where this AI detective really shines. From education to hiring to social writing platforms, GPTZero is making waves in a variety of fields.

Let’s dive into some of these use cases!

1. Education

GPTZero applications in education

First up, let’s talk about education. With the rise of AI, there’s been a surge in AI-written text in the academic world.

Students might be tempted to let an AI do their homework for them, but GPTZero is here to keep things fair. Teachers can use GPTZero to check student work and ensure it’s all original content. It’s like having a high-tech plagiarism detector but for AI!

2. Hiring and Recruitment

GPTzero use in hiring and recruitment

Next, let’s look at hiring and recruitment. These days, it’s not uncommon for companies to receive hundreds, if not thousands, of applications for a single job posting. Sifting through all those resumes and cover letters can be a daunting task.

But with GPTZero, recruiters can quickly identify if an application was written by humans or AI, helping them focus their attention on the most promising candidates.

3. Social Writing Platforms

GPTzero use for social writing platforms

Social writing platforms and services are another area where GPTZero is making a difference. These platforms are all about authentic human connection and expression, and GPTZero helps ensure that’s what they remain.

By identifying AI-written content, GPTZero helps maintain the integrity of these platforms and the authenticity of the interactions they facilitate.

And these are just a few examples. The beauty of GPTZero is that it’s a versatile detection tool. Anywhere there’s text, GPTZero can be there, helping to distinguish between human and AI content.

What Are the Limitations of GPTZero?

Limitations of GPTZero

GPTZero’s classifier has limitations, and the tool’s developers don’t recommend educators use its results as a basis for penalizing students. They instead recommend teachers use the results as part of a comprehensive evaluation of student assignments.

There is a chance that human content is misidentified as fake content, and vice versa. The model has a higher accuracy when classifying entire documents compared to individual paragraphs, and even more so compared to single sentences.

The model’s accuracy also improves when the input text closely resembles the content of its training dataset, which comprises a wide variety of human and AI-created text, with the bulk being English prose.

GPTZero’s classifier isn’t designed to detect AI-produced text that has undergone substantial alterations, and it may occasionally mislabel highly formulaic text as AI-produced.

It’s crucial to keep the error rate in mind when using GPTZero as an AI content detector. Use its results as part of your assessment, but remember that it can get things wrong.

Final Thoughts

In a world where AI-made text is becoming increasingly prevalent, GPTZero stands as a beacon, helping us distinguish between human and AI-generated content.

From education to hiring to social writing platforms, GPTZero is making its mark as an AI text detector. Its ability to detect a wide range of AI language models, provide nuanced scoring, and continually learn and improve makes it a powerful ally in our increasingly digital world.

But perhaps the most exciting thing about GPTZero is its potential. As AI technology continues to evolve, so too will GPTZero and its AI detection abilities. The future of AI is here, and with GPTZero, we’re ready to meet it head-on!
