PaperCheck

PaperCheck is a web service that lets students and academics run their papers through Turnitin's official AI and similarity detection before submitting to a university. You upload your document (DOCX, PDF, TXT, or RTF), and within 5–15 minutes you get a real Turnitin report showing both the AI-generated percentage and the similarity score. The goal is simple: give you a preview of what your institution will see, so you can revise and submit with confidence.

How does it work? After you upload, PaperCheck strips identifying metadata from your file to protect your privacy. The file is processed through Turnitin's official detection engine — the same one used by most universities. You receive a detailed report that breaks down AI-generated text, AI-paraphrased sections, and similarity matches. Each flagged section comes with a plain-English explanation, so you know exactly what to revise. Your upload is automatically deleted within 24 hours and is never added to a university repository. Reports are accessible for 30 days, then removed.

PaperCheck is built for students who want to avoid surprises before a final submission. It's also useful for academic writers who need to check their own work or understand how Turnitin scores different types of writing. The service is independent — not affiliated with Turnitin LLC — and offers a money-back guarantee if the report fails to deliver. With no subscription required and one-time pricing starting at $4.99 per check, it's a straightforward pre-submission safety net.
