What is GPTZero and how does it detect AI?

GPTZero is the most trusted AI detector for education, designed to check if content was written by large language models such as ChatGPT, GPT-4, GPT-5, GPT-6, Gemini, Claude, Perplexity or Copilot. It provides document-level, sentence-level and even word-level analysis, highlighting the specific parts of a text that appear AI-generated. Like all AI detectors, GPTZero isn't perfect, and short texts or highly edited passages can make detection harder. This is why we recommend using GPTZero as a conversation starter to using AI responsibly in the classroom.

Why do teachers and educators need an AI detector?

More and more students are now using generative AI tools to create essays in mere seconds, and for educators, this brings up new questions around academic integrity and helping students see the value of their own voice. An AI detector can give teachers (and students) peace of mind when reviewing submissions, by quickly flagging work that appears to be AI-generated.

Which AI models can GPTZero detect?

GPTZero detects text from ChatGPT (GPT-3, GPT-4, GPT-5, GPT-6), Gemini, Claude, Copilot and other major services.

What languages can you scan using GPTZero?

Currently, GPTZero supports English, Spanish, French, German, and more. Detection is strongest in English prose, but the model continues to expand to other languages.

How accurate is GPTZero's AI detector?

Independent sources (including TechCrunch) have called GPTZero the best and most reliable AI detector available. In our internal testing, GPTZero achieves high accuracy rates while maintaining one of the lowest false positive rates in the industry, meaning it's far less likely to wrongly accuse a student of using AI.

How do I share an AI scan report with my student?

You can share results via link directly in GPTZero or download a PDF report to email or print.

I'm an educator who has found AI-generated text by my students. What should I do?

When a scan suggests AI use, we recommend: Ask students to show their process (through edit history or in-person assessment). Use GPTZero's Writing Reports to replay how a student wrote. Check for patterns across multiple assignments rather than relying on a single instance.

What can I do as an educator to reduce the risk of AI misuse in my classroom?

In short, by designing assignments that highlight the human value of education. For example: Help students understand the risks of using AI in their work (to learn more, see this article ), and the value of learning to express themselves. Ask for personal reflections or critiques of AI-generated answers. Collect multiple drafts over time. Incorporate non-text formats, like presentations, videos, or audio recordings. Set expectations upfront that work may be checked with GPTZero.

Don't just hear it from us.

Hear what our teachers, ambassadors, and schools are saying.

Randi Weingarten

President, American Federation of Teachers

This tool is a magnifying glass to help teachers get a closer look behind the scenes of a document, ultimately creating a better exchange of ideas that can help kids learn and get excited about school when AI is used appropriately.

Jonathan Langlois

University of the Ozarks

I have been able to lead a couple of campus wide faculty workshops where GPTZero was a main feature... I have heard back from people who had a semester of AI slop that with the use of GPTZero now are getting student writing again.

Dr. Arpita Gupta

KLEF

The program has enabled me to support educators in understanding responsible AI use, academic integrity, and the evolving role of AI detection in education.

Vincent Kebwaro Maige

Chuka University

Serving as a GPTZero Ambassador has been a valuable experience. It has allowed me to advocate for the responsible use of AI in academic work... The experience has also strengthened my leadership, communication, and AI literacy skills.

Catherine Moore

Moravian Academy

I love having the confidence to share with other colleagues our observations and challenges of GenAI use in the classroom. I have shared GPTZero with so many of my colleagues that now my school subscribes so that all of the faculty may use it.

Alisa Coop

Glendale Community College

The tool sparks great conversations, and honestly, that conversation is the real win. Awareness, not enforcement, is what actually changes how students think about authorship.

Michael Setiawan

Bina Nusantara University

GPTZero is my personal driver to help detect AI. The other features are also great, such as hallucination and AI grader... I also encourage my students to use GPTZero to help them record their writing process as evidence of their authorship.

Uldis Karlovskis

Riga Technical University

We had a great time trying to guess which texts were AI-generated and which were human-written, then comparing our predictions with GPTZero's results... the tool generally performs very well.

Rosemary Evans

University of Toronto

GPTZero provides the support I require as an educator to authenticate online information... It alerts me to hallucinations including citations which are not real. I do not use GPTZero punitively but rather as a teaching and learning tool.

Ray Stribling-Vergara

Evanston Township High School

I use GPTZero as the first line of defense after my intuition tells me that the writing a student provides does not 'sound like them.'

Ariella Pardo

College Montmorency

I now create AI chatbots for my students to support review and independent practice while promoting academic integrity and AI literacy in the classroom.

GPTZero’s feedback aligns well with my sense of what is going on in the writing - almost line-for-line.

Christa Bell

Lafayette County School District

Being a GPTZero Ambassador has been a meaningful extension of my work as a school librarian and educational leader... It's exciting to help schools feel more confident as they adapt to this rapidly changing technology.

Papa Ezra

Zetech University

Over the last few years, GPTZero has been a great professional companion. It came in handy in grading and assessment of papers as well other relevant documents.

Jennifer Fisch-Ferguson

Mott Community College

It's been really great to learn about generative AI in both the possibilities and limits. It's a great community with people willing to share experiences.

Alden Dearborn

Randolph High School

It's been so gratifying to empower my colleagues through GPTZero's professional development. These tools have helped us find ethical places for AI in the classroom while holding students accountable for producing their own work.

Austin Yoo

The Princeton Review Korea

Using GPTZero, I have been able to identify false practice patterns more clearly and guide students toward honest academic habits. GPTZero has helped me support students in producing work that reflects their own thinking.

Elmira Gurses

I care deeply about the spread of uninformed and unrestricted use of AI in schools... there are smart AI monitoring services and scales we can use to implement a sustainable system that does not forbid AI but makes it a partner in education.
