What is DupliChecker?
DupliChecker is a web based plagiarism checker that scans up to 25,000 words per search using AI based technology and partial match detection at the paragraph level, so it can catch reworded or restructured copying rather than only exact matches. It accepts copy and paste, URL, and file upload input across formats including doc, docx, odt, pdf, rtf, and txt, and can import files directly from Google Drive and Dropbox. A free AI content detector, grammar checker, and paraphrasing tool are bundled alongside the core checker.
A limited free version is available without signup, while paid access is sold in weekly, monthly, and yearly tiers offering larger word counts and search quotas, plus a Plagiarism API for integrating real time checks into other websites.
