X Detector

X Detector is a free AI content detection tool built for students, teachers, and anyone who needs to know whether a piece of text was written by a human or generated by an AI. It accurately identifies content produced by ChatGPT, Claude, Gemini, and other major AI models, supporting detection in over 20 languages so it works for classrooms and workplaces around the world. Unlike many AI detectors that charge for basic features, X Detector is completely free — with no compromises on accuracy, privacy, or multilingual coverage. It's designed to safeguard the integrity of critical text, whether you're an educator checking student submissions, a publisher verifying original authorship, or simply someone who wants to know if what they're reading was truly written by a person.
