Turnitin AI Checker

Turnitin AI Checker (PaperCheck) is a private, pre-submission service that delivers official Turnitin AI detection and plagiarism reports for uploaded documents.

What is Turnitin AI Checker?

Turnitin AI Checker, operated by PaperCheck, is a web-based service that allows students to upload their papers (DOCX, PDF, TXT, or RTF) and receive an official Turnitin report showing both AI detection (AI-generated and AI-paraphrased percentages) and similarity scores. Most reports are processed in 5–15 minutes; 99% complete within 30 minutes. Files are stripped of metadata and automatically deleted after 24 hours, never added to any repository. PaperCheck is an independent service not affiliated with Turnitin LLC.

FAQ

Is the report real, not an AI-generated fake?

The report is generated through official Turnitin processing, not by another AI tool. PaperCheck has direct access to Turnitin's detection engine, producing the same AI and similarity scores an institution would see.

Will my paper be stored in a repository?

No. Uploaded files are stripped of metadata and automatically deleted within 24 hours. They are never added to Turnitin’s institutional repository or any other database.

How fast is it?

Most reports are delivered in 5–15 minutes; 99% within 30 minutes. If the service fails to deliver, you get a full refund.

Can AI detection flag human writing?

Yes. Turnitin’s AI detector can produce false positives. The report includes a disclaimer: treat scores as a review prompt, not proof of misconduct.

Are you affiliated with Turnitin?

No. PaperCheck is an independent service providing a pre-submission check using Turnitin's technology but is not associated with Turnitin LLC.
