GPTZero: AI Detection & Writing Replay
Extension Actions
- Extension status: Featured
Bring AI detection, citation checks, live essay feedback, and writing replays directly into Google Docs and your workflow.
The GPTZero Extension is the best solution for enhancing critical thinking and human writing, as recently featured in The New Yorker, New York Times, and Harvard Business Review.
The new Google Document experience is custom built for teachers, students, and researchers. It includes four new powerful features:
(1) Live AI detection checks instantly as you write
(2) Customizable feedback and writing comments in Google Docs
(3) Writing video replay and report, with a new typing pattern analysis
(4) Bibliography, citation, and a research-focused fact check
➤ What is our writing video replay?
GPTZero’s Writing Replay brings your Google Docs writing process to life, showing exactly how a piece was written, edited, and pasted. Now supporting multiple editors, switch to see how different writers contributed to the final document.
➤ What makes the GPTZero Writing Report different?
Unlike other writing replay solutions like Draftback, Brisk Replay, Grammarly Authorship, or Turnitin Clarity, the GPTZero Writing Report includes:
• Multi-user detection: See how much each writer contributed by percentage.
• Instant replay: Fast-loading, high-resolution writing playback.
• Activity insight: Identify frequent edits, pastes, and writing bursts.
• Human vs. AI analysis: Built-in AI detection flags large pastes and unnatural text.
• Typing pattern insights: Our proprietary algorithm uncovers human typing behaviors.
• Security: Enterprise grade data security and privacy, SOC2, and FERPA compliance.
➤ How does GPTZero writing and typing analysis work?
GPTZero’s first-of-its-kind natural typing analysis constantly runs AI detection on large copy-pastes, and layers a proprietary algorithm trained on millions of documents that identifies human typing and natural editing patterns.
➤ What is GPTZero Bibliography and Source Check
Check writing for AI-hallucinated and inaccurate bibliographies, uncited claims, and plagiarism. Then receive suggestions to improve sources and citations.
➤ What is GPTZero Writing Feedback
Fully customize giving feedback by uploading a rubric and assignment details and specifying the focus. Feedback is live-drafted directly into Google Docs comments for convenience.
➤ How can teachers integrate GPTZero into a course?
Thousands of educators have added GPTZero directly into their syllabus as an assistant for students during their writing process.

- GPTZero is an excellent tool for checking whether writing may have been generated by AI. It is simple to use, fast, and helpful for students, teachers, and writers who want more confidence in the originality of written work. The layout is easy to understand, and the results are clear without being confusing. Overall, GPTZero is a reliable and useful resource that makes AI detection much easier. Highly recommended!
- Adeniran Samuel
- I loved how GPTZero made it easier to check writing. The website is pretty easy to understand and it gives the results quickly. The Google Doc extension is great because you don't have to open a new tab just to check if a piece of writing has been written by AI. It's not perfect but it's a good way to understand patterns in AI writing and how to make writing better. It's a must for students or writers.
- Quinn Singer
- I’ve had a really good experience using ChatGPT Zero. The website is easy to use, and it gives quick feedback when checking writing for AI-generated content. I like how simple the layout is because it makes uploading and reviewing papers fast and convenient. It has helped me better understand how AI detection tools work and what kinds of writing patterns they look for. While no detector is perfect, ChatGPT Zero is useful for getting a general idea of how writing may appear to professors or other readers. Overall, it’s a helpful tool for students who want to review and improve their work before submitting assignments.

- I’ve been really impressed with GPTZero so far. It’s one of the few AI detection tools I’ve tried that feels both accurate and easy to use, especially on longer, more formal pieces of writing. The interface is clean and straightforward, so you can paste in text and get a clear probability score for AI-generated content without needing any technical background.

- Keeda Beach
- works great, helps me avoid phrasing that is used in AI to make my writings sound more original and unique
- Robert Seligman
- It works I'm in school and was originally flagged for using tools like gramarlly or Wordtune because they use AI to fine tune your writing but GPTzero helps to make sure that can never happen. IT JUST WORKS!!!
- Kathie Malcomb
- I am a 10th Grade English teacher and this tool is indispensable. I've always been fairly certain of my own ability to detect AI writing, but I also want to give students the benefit of the doubt. Now, when I suspect that a student is submitting AI-generated work I use GPTZero to check it, and I have the confidence to return the work if necessary. Even better, my students know I'm using AI-detection, so they are starting to take their own writing more seriously. Thank you for creating this for teachers!
