Can Turnitin Detect Chinese AI Writing?
Independent guide. Not affiliated with Turnitin, LLC. Read the Turnitin disclaimer.
No. As of October 2026, Turnitin's AI detector does not support Chinese. Chinese text still gets a similarity report, but no AI score.
The mixed-language problem
Turnitin says mixed-language documents aren't supported. A 2026 report in an HKBU student publication described a mixed Chinese-English project scored 40% AI that dropped below 20% once the languages were separated. If your paper mixes languages, check it first.
Translation raises English AI scores
Writing in Chinese and translating with AI tools produces English that Turnitin's English model, which includes paraphrase and bypasser detection, often flags.
What to do
- Submit English sections in a separate file where allowed.
- Check the English version on Turnitin ($3.50).
- Have translated English rewritten by a person: $5.99 per 200 words.
