PaperCheck

PaperCheck helps students check their papers against Turnitin before they submit — using the same official Turnitin AI writing detection and similarity engine instructors actually use, not a third-party approximation.

Upload a DOCX, PDF, TXT, or RTF file and get back an official Turnitin AI + similarity report, most reports in 5–15 minutes. The report breaks down what's flagged as AI-generated vs. AI-paraphrased alongside a similarity score, so students can review and revise before their real submission instead of being surprised by it.

Key features:

• Official Turnitin AI + similarity report, not a knockoff detector
• Most reports back in 5–15 minutes, 99% within 30 minutes
• Metadata stripped before processing; files deleted within 24 hours
• Never added to a university's Turnitin repository
• One-time payment, no subscription — plans from $4.99
• Free AI-only check available for a quick first estimate PaperCheck is an independent service and is not affiliated with, endorsed by, or sponsored by Turnitin LLC.
