What is GPTZero?
GPTZero is an AI content detection tool for examining pasted text and documents for passages that may have been generated by language models such as ChatGPT, GPT, Gemini, Claude, and Llama. It also includes writing-quality features so users can review possible AI involvement alongside the text itself. A scan provides an overall assessment and highlights phrases that the system identifies for closer inspection.
The product is available as a web detector with browser, document, writing-report, and writing-replay workflows, and it connects with Google Docs, Canvas, Google Classroom, Zapier, and an API. Teachers and students can use it to support conversations about academic integrity and writing development, while publishers, recruiters, marketers, and other teams can review documents where authorship and writing quality matter. Detection results are best treated as evidence for review rather than a final judgment about a writer or document.
Key features of GPTZero
Multi-model text detection
GPTZero scans text for patterns associated with AI-generated writing and covers models including ChatGPT, GPT, Gemini, Claude, and Llama. This makes it useful for an initial review of essays, articles, submissions, and other written documents.
Document and sentence-level results
A scan combines an overall assessment with more granular text-level findings. GPTZero can highlight phrases or sentences that warrant closer review, helping users inspect the relevant parts of a document instead of relying only on a single summary result.
Writing and authorship review
Writing reports, video replay, human-writing verification, and plagiarism checking add context beyond an AI-likelihood result. These capabilities support reviews that need to examine writing transparency, the authoring process, and whether material appears to come from outside sources.
Education and workflow integrations
GPTZero can be used through a Chrome extension and connected with Google Docs, Google Classroom, Canvas, Zapier, and an API. These integrations bring detection into browsers, classroom platforms, document workflows, or systems built by an organization.
