GPTZero is changing the way AI-written content is detected, ensuring that human creativity is preserved. Since launching the first public AI detector in 2022, they have become the leader in detecting outputs from models like ChatGPT, GPT-4, Google-Gemini, and LLaMa. They go beyond simple detection to investigate the sources of AI content, ensuring thorough and reliable results.

They were the first to offer sentence highlighting, helping users understand why certain parts of a text were flagged as AI-generated. This feature makes their AI reports clear and trustworthy. Their accuracy is backed by independent benchmarking through a partnership with Penn State, proving that GPTZero is best in class.

Top researchers from Princeton, Caltech, MILA, Vector, and OpenAI work with them to keep their detection methods cutting-edge. They also tackled AI biases with a new de-biased model launched in July 2023, based on data from Stanford University. Security is a priority for them, meeting high standards through SOC-2 and SOC-3 certifications.
