Duplicate Content

Duplichecker is a plagiarism checking tool that can be used to check the originality of content before it is uploaded or to verify if existing content has been used without permission by a third-party source. This tool supports multiple languages, including English, French, Spanish, Russian, Portuguese, Dutch, Indonesian, Italian, and Arabic. Besides the plagiarism checker, Duplichecker.com also offers other tools to help users improve their SEO strategy.

What is Duplichecker?

Duplichecker is a free online plagiarism checker that verifies whether content is partially or fully plagiarized on the internet. It works by analyzing each sentence and comparing it to existing content online. Users can paste text, drop files, or upload documents (.tex, .txt, .doc, .docx, .odt, .pdf, .rtf) by URL. This automation makes plagiarism detection easy and accessible to everyone. Checking content manually across millions of sites and billions of words is impractical, highlighting the importance of using a plagiarism checking tool. Duplichecker allows up to 1,000 words to be checked at a time for free, with paid versions offering more features and larger word limits.

How to Use Duplichecker for Plagiarism Checking

  2. Paste the text to be checked or import a document (formats: .txt, .doc, .docx, .odt, .pdf, .rtf).
  3. Click the “Check plagiarism” button.

After processing, Duplichecker displays the results, showing the percentage of unique content and plagiarized content, with plagiarized passages highlighted along with their sources. If plagiarism is detected, users can use the “BEST Paraphrasing Tool” to rewrite the passages and achieve unique content.
