“This tool helped me catch AI-written sections I didn’t even realize were there. It saved my grade and gave me the confidence to submit without worry.”
“The grammar suggestions were a game changer. It’s not just a checker — it actually helped me improve clarity and structure in my writing.”
“Fast, accurate, and super easy to use. I ran a scan 30 minutes before class and caught two issues I fixed right away. Highly recommend.”
“At McGill, originality matters. This scan quickly flagged citation issues and suggested improvements I hadn’t even considered. A must-have for students.”
“The writing feedback was incredibly useful — especially for grammar and flow. It helped me meet the strict academic standards at Oxford.”
Is AI-Generated Writing Considered Plagiarism?
AI tools like ChatGPT, Gemini, and Grok can generate text that sounds human—but submitting it without credit can still violate academic integrity policies. Many schools now classify uncredited AI assistance as a form of dishonesty, even if the content isn’t directly copied from another source.
That’s why detecting AI-written content is just as important as checking for plagiarism. Paperdue’s dual-scan technology highlights sections that may trigger AI detection at your school, giving you the opportunity to revise and submit with confidence.
Maintain Academic Integrity in the Age of AI
AI writing tools have revolutionized how students approach assignments—but they’ve also introduced new risks around originality, authorship, and academic honesty. Upholding integrity now means more than avoiding copy-paste—it requires proving that your work is truly your own.
Paperdue.ai helps you stay compliant and confident. Instantly scan for AI-generated content, identify potential plagiarism, and improve your writing with guided tools for citations, paraphrasing, and editing. Whether you’re submitting an essay, research paper, or thesis, our platform ensures you meet today’s academic standards.
Frequently Asked Questions
Answers to common questions about scanning, privacy, and pricing.
Yes! Paperdue’s scanner checks for both — it scans billions of academic sources for plagiarism and also uses advanced models to flag AI-written sections, helping you stay compliant with school policies.
We offer both! You can choose a single document scan with no commitment or upgrade to our monthly plan for multiple scans daily and access to all our writing tools, example essays, writing tutorials, and more.
No. Your document is never shared, published, or made accessible to others. All scans are processed securely and privately. To improve detection accuracy, our system may compare patterns—not content—against prior submissions, but your actual writing remains confidential at all times.
