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 trained using a mix of texts from humans and computers. The goal? Make sure it correctly picks out which is which.

Sure, GPTZero is pretty good at figuring out if a short piece of writing is made by a computer or a person. But it’s even better at spotting long articles written by a computer. When I tested it with short texts from GPT-4, GPT-3, and even humans, GPTZero usually thought a person wrote them. However, when the text got longer, up to 4,296 characters, GPTZero could tell it was partly written by a AI.

Sure, for something called “burstiness,” we got a score of 45. If you scroll down on the website, there’s a button that says “Get GPTZero Result.” When you click it, you get a final score and an idea of whether the writing is made by a person or computer. That’s what happened with the paragraph we were talking about.

Of course! I’m excited to see how GPTZero does with different kinds of writing. I think it will probably know the thesis is written by a person because it’s complex. For your blog post, the score might be somewhere in the middle. Ready to see your thesis paragraph when you are!

Sure! GPTZero thought the writing was most likely done by a person because the sentences were really complex. It didn’t think a computer wrote it.

Netus AI tested GPTZero with our own blog post about AI Detector Tools to see if the AI Detectors is accurate. The score we got was “This text is likely to be written by a human” which wasn’t a big surprise as out paraphraser is the most advanced. This the result we get with all the AI article Detector tool.

Support and Community

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 5,000 characters per entry. 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. is gpt zero legit
