An AI detector is a tool designed to analyze text and determine whether it was generated by AI models such as ChatGPT, with the core goal of validating content originality and authenticity.
Some AI detectors offer free basic services, such as analyzing text up to a certain character limit; advanced features or bulk processing may require a paid version.
Many professional AI detectors pledge user privacy, explicitly stating that they do not store or share the uploaded text, and delete it after analysis.
