T-Checker

AI content detection

T-Checker is a free AI writing detection tool that provides instant AI detection scores and sentence-by-sentence highlighting results, and can be used without registration. Users can paste texts such as essays, papers, and academic drafts into the input box, and the tool analyzes writing patterns such as sentence rhythm, repeated wording, predictable structure, and AI-like academic tone, giving an AI probability score, risk level, and sentences that may require attention. The tool is aimed at students, educators, and academic writers, and is used before submission to check whether articles, research papers, discussion posts, application essays, and similar texts contain traces of AI generation or AI assistance, and serves as a reference for writing review, helping identify parts that need additional personal reasoning, specific examples, and adjustments to sentence variation. Official materials do not state its relationship with the official Turnitin system, nor do they provide specific information such as pricing or platforms.
