Start a Free AI CheckCheck AI-Written Text Before Submission
TurnDetect is built for writers who need a fast way to review AI-generated writing signals in academic work. It can help identify passages that read too polished, too repetitive, or too generic before the final version is submitted.
Use it as a practical pre-submission AI checker for essays, research papers, application statements, discussion posts, reports, and thesis chapters. The goal is not only to get a score, but to understand which parts of a draft may need clearer reasoning, more personal phrasing, or stronger source support.
Tip: For best results, check complete paragraphs instead of isolated sentences. AI-writing patterns are easier to evaluate when the tool can see structure, transitions, and repeated phrasing.

What text length works best?
