FAQs
What is GPTZero?
GPTZero is the first and leading AI detector that allows you to identify content generated by LLMs like ChatGPT. Founded in Jan 2023, it has served over 10M users and works with 100+ organizations.
How does AI detection work?
AI detectors look for patterns in text, such as perplexity, burstiness, and style, to determine if it was machine-written. GPTZero uses a proprietary model with hundreds of factors for accuracy.
Is GPTZero's AI detector accurate?
Yes. Independent benchmarks show GPTZero is the most accurate AI detector with 99% accuracy for AI vs. human text, and 96.5% for mixed documents, minimizing misclassifications.
How do I use GPTZero's AI detection tool?
Paste text or upload files, then press 'Scan'. Results show AI-generated percentages and highlights. For scans over 10k characters, create a free account. A Chrome Extension is also available.
Who is GPTZero for?
GPTZero is primarily for educators and students in 3500+ colleges and institutions, guiding academic integrity. It also serves publishers, recruiters, copywriters, and businesses.
Does the GPTZero AI Content Checker only detect ChatGPT outputs?
No. GPTZero works across a wide range of AI models including ChatGPT, GPT-5, GPT-4, Gemini, Claude, Llama, and Deepseek. Its model is constantly updated with new training data.
Which languages does GPTZero support?
GPTZero fully supports English, German, Portuguese, French, and Spanish with industry-leading accuracy. It is also used in many other languages across over 100 countries globally.
What is the best AI detector?
GPTZero is consistently rated most accurate and reliable, verified by independent sources like TechCrunch. It's finetuned for student writing and has minimal false positives for ESL learners.
What are the limitations of AI Detectors?
No AI detector is 100% accurate, and AI changes constantly. Results should not be used for punishment. Accuracy improves with longer inputs and is strongest on English prose. De-biased for ESL.
What can I do as an educator to reduce the risk of AI misuse?
Help students understand risks, create AI-proof assignments (e.g., personal experiences, live discussions), require multiple drafts, use difficult-to-generate mediums, and set clear expectations.
I'm an educator who has found AI-generated text by my students. What do I do?
Have students demonstrate understanding in controlled settings, ask for writing process artifacts (drafts, edit history), or look for a long-term pattern of AI use, not just a single instance.
What is GPTZero's source finder?
GPTZero's source finder detects potentially misleading claims in text and recommends sources that support or contradict them, allowing users to dive deeper into analysis and provide context.
Does GPTZero's source finder use AI?
Yes, AI is used to detect claims and pair them with relevant sources. GPTZero actively filters out potentially AI-generated content to ensure reliability of sources provided.
Does GPTZero's source finder work as a fact checker?
No, it doesn't take a stance on truth. It indicates whether online evidence contradicts, debates, or supports a claim using high-quality sources, but does not endorse specific viewpoints.
How do I use and interpret the results from your API?
The API returns 'document_classification' (HUMAN_ONLY, MIXED, AI_ONLY) with class probabilities and a confidence category (high, medium, low). It also highlights AI-detected sentences.
