Democratizing AI
Transparency.
We are a team of researchers, linguists, and engineers dedicated to building the most accurate bridge between machine-generated text and human creativity.
The Human Firewall
Between 2022 and 2026, the internet was flooded with synthetic media. The “Signal-to-Noise” ratio of human thought collapsed. We saw a vital need for a tool that could distinguish between the statistical probability of an LLM and the chaotic brilliance of a human mind.
We didn’t build GPTZero to punish students or police writers. We built it to preserve the value of human originality. Our mission is to support educators, journalists, and editors in verifying authenticity without compromising privacy.

Core Principles
The foundation of our research lab.
Precision
We don’t rely on a single model. Our engine aggregates analysis from GPT-4o, Claude 3.5, and Gemini detection vectors to minimize false positives.
Privacy
We are not a data farm. Our “No-Log” policy ensures that text scanned by guest users is processed in volatile memory and never used to train our models.
Accessibility
Truth shouldn’t be paywalled. We provide professional-grade detection tools for free, without mandatory registration, to students worldwide.
Beyond Guesswork
Unlike other detectors that look for simple keywords, our engine performs a deep Stylometric Analysis. We map the “Linguistic Entropy” of a document.
01. PERPLEXITY
Measures the complexity of text. AI models are trained to minimize perplexity (be predictable). Humans are naturally chaotic and unpredictable.
02. BURSTINESS
Measures the variation of sentence structure. Humans write in “bursts”—short sentences followed by long, complex ones. AI is monotonous.
AI as a Co-pilot, Not a Replacement.
We believe in the transparent use of AI tools. Using AI for brainstorming is innovation; presenting AI output as your own is deception.
Behind the Code
GPTZero was founded by a collective of NLP (Natural Language Processing) researchers and Princeton computer scientists. Our team operates globally, constantly stress-testing our models against the latest adversarial attacks (like jailbreaks and paraphrasing tools) to ensure our detection remains the industry gold standard.
