What is free AI detector?
Free AI detector refers to people looking for no-cost tools that estimate whether a piece of text was written by AI tools such as ChatGPT, such as GPTZero, ZeroGPT, QuillBot's and Grammarly's detectors. People search it to check essays, articles and applications, or to test their own writing before submitting it. In practice, the users are teachers, students, editors and recruiters. Detection is unreliable, with false positives against human writers, and companion tools that rewrite text to evade detection grow alongside. It is a large, freemium category with clear demand and an uneasy accuracy problem.
