What is GPTZero? [Free version is available with less components than fee based versions] “GPTZero is the first and leading AI detector that allows you to identify specific content in a document or text that has been generated by a large language model (LLM), such as ChatGPT. Founded in January 2023, GPTZero has served over 10 million users to date and works with 100+ organizations in education, hiring, publishing, legal and more. AI detectors work by looking for patterns in text that are more likely to have been written by a machine than a human. The most common factors they look for include: GPTZero uses its own proprietary model that takes hundreds of factors into consideration and boasts the highest detection accuracy in the industry…Independent benchmarks, like our partners at Penn State’s AI Research Lab, and our own large-scale testing show that GPTZero is the most accurate AI detector, with a 99% accuracy rate when spotting AI-generated text vs. human writing, a false negative rate under 2%, and a false positive rate under 1%. This means we correctly classify AI writing 99 out of 100 times, and keep misclassification of text to an absolute minimum. Unlike many competitors, GPTZero can reliably detect “mixed documents” (where human and AI writing are combined) with 96.5% accuracy rate. While no AI detector can ever truly be 100% perfect, we are committed to being a leader in responsible adoption of AI generation and AI detection technologies…”
