About GPTZero: AI Detection & Writing Replay

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.
