What is an AI Detector?

An AI detector is a tool designed to analyze text and determine whether it was likely written by a human or generated by an AI system, such as ChatGPT, Gemini, Claude, Grok, DeepSeek, or other language models.
You can use CopyChecker’s AI checker to find whether a human or LLM wrote something without having to jump through hoops with our AI content checker.
According to recent statistics, about 50% of content is now AI-generated. While not inherently bad, ensuring content is not written with AI by scanning it with an AI text detector is important.
