GPTZero is a powerful tool that detects whether text is AI-generated or written by a human. Free and open-source, it allows anyone to check the authenticity of their content with an impressive accuracy rate of up to 98%.
How Does GPTZero Work?
Based on extensive research, GPTZero’s algorithm was developed by Edward Tian, a Princeton University graduate. It analyzes text through statistical methods, identifying telltale markers of AI generation. Typically, AI-generated text is characterized by simpler language and repetitive structures, whereas human-written content is more varied and complex. GPTZero detects content generated by leading AI models, including ChatGPT, GPT-3, GPT-4, Bard, and LLaMA 2.
