What is GPT Zero?

When you suspect an essay or application is AI-generated, GPTZero offers a quick verification layer. Teachers and hiring teams use it most. The free tier covers basic detection on limited documents per month, available through a web interface, Chrome extension, or API. Plagiarism checking is included. Reliability is the catch. Detection accuracy varies by writing style. Human work gets flagged as AI sometimes. AI content can pass through, particularly from newer models. It's a first-pass filter, not definitive proof. Good for educators checking assignments and recruiters verifying application responses. Need absolute certainty about authorship? Dealing with sophisticated models? Look elsewhere.
