Reviews
- Trustpilot Review: One reviewer tested partially paraphrased, fully rephrased, and completely copied text and reported accurate detection results, expressing surprise that a free checker worked so well. Another highlighted the “contextually correct vocabulary replacement” in Duplichecker.com’s paraphrasing tool, which helped expand word choice and add more sophisticated jargon, while a business owner praised support for offering a custom plan with “up to 20% off pricing.” Multiple comments also noted multilingual grammar and plagiarism checks as a major convenience, though one user complained that the free version contains too many ads.
- essayscam.org Review: Opinions split sharply in the forum thread. One freelance writer said it is “100% free to use” and valued the ability to paste text or upload .doc or .txt files for plagiarism checks, claiming it helps correct mistakes. Others warned that free plagiarism scanners may collect and resell submitted essays, argued the tool is “not 100% reliable,” and advised avoiding services like Duplichecker.com due to copyright and data risks.
- aidetectplus.com Review: After weeks of daily testing, the reviewer credited Duplichecker for its multilingual grammar checker and the option to download a plagiarism report instead of taking screenshots. The article also criticized “expensive subscriptions that trap you” and claimed unused monthly credits disappear, while calling customer service “a mess” when handling payment or refund issues.
