GPTZero

GPTZero is an AI detection platform for identifying machine-generated text. It combines a text detector with a Chrome extension, a plagiarism checker, writing-process verification, and educator-focused classroom tools.

Sentence-level AI detection

Paste text or upload a document and get an overall AI probability score plus a sentence-by-sentence breakdown of which parts look machine-written.

Multi-model coverage

Flags AI text from major model families including ChatGPT, Gemini, Claude, Llama, and others, rather than training for a single model.

Browser and docs extensions

A Chrome extension and Google Docs add-on bring scanning into Gmail, Docs, Classroom, and other surfaces you already work in.

Plagiarism checking

Checks content for copied passages from outside sources so you can separate AI-generation questions from originality questions.

強み・メリット

+Sentence-level highlighting shows why a passage was flagged instead of only giving a score
+Covers text from many different AI model families, not just one chatbot
+Integrations with Chrome, Google Docs, Canvas, and Google Classroom fit existing school workflows
+Publishes concrete compliance claims (SOC 2 Type II, FERPA, GDPR, CCPA) that institutions can review
