Red Paper checks your documents for plagiarism against published papers, journals and web sources — and flags AI-generated passages in the same scan.
WHAT YOU GET
• Similarity report — a percentage match against published academic work and the web, with the matching passages shown against their sources.
• AI content detection — machine-written passages flagged alongside the similarity score, reported separately so the two readings are never confused.
• Originality certificate — a shareable PDF you can attach to a submission or send to a supervisor.
• 196 languages — the language of your document is detected automatically.
HOW IT WORKS
Upload a PDF, DOCX, DOC or RTF file, or paste your text. The scan runs on our servers and you get a notification when the report is ready. Reports stay in your account, so you can open them again later or download the certificate any time.
WHO IT IS FOR
Students checking a thesis or assignment before submission. Researchers preparing a manuscript for a journal. Editors and institutions verifying submitted work.
