AI detection FAQ
Can Turnitin detect ChatGPT?
Quick answer
Turnitin offers AI-writing detection that estimates how much of a document may be AI-generated, but like all detectors it can produce false positives and false negatives, especially on edited or mixed drafts.
Turnitin added an AI-writing indicator that reports an estimated percentage of AI-generated text. It is separate from its similarity (plagiarism) score and is intended as a signal for instructors to review, not an automatic verdict.
No detector — Turnitin included — is perfectly reliable. Short submissions, heavily edited AI output, paraphrased text, and non-native English writing can all shift results. Treat any AI percentage as a starting point for a human conversation, not as proof.
If you want explainable, passage-level evidence rather than a single percentage, DeepDetector focuses on showing which sentences carry AI-writing signals and how confident the review is, so reviewers can interpret uncertainty responsibly.
