What is AIDetector?

AIDetector is a free online tool that analyses text to identify whether it was generated by AI models such as ChatGPT, GPT-5, Claude, and Gemini. You paste or upload text, and the tool returns a detection result indicating the likelihood of AI authorship. It's designed for educators checking student work, content creators verifying authenticity, and publishers concerned about AI-generated submissions. The tool accepts multiple file formats, making it practical for various workflows. Since AI detection remains an imperfect science, AIDetector should be treated as one signal among others rather than definitive proof of authorship.
