DupliChecker offers a widely-used plagiarism detection tool called Plagiarism Checker, favored by numerous individuals and institutions globally.

Who Can Use It:

  • Content Writers - To check articles, blog posts, and other written content for originality.
  • SEO Professionals - To analyze content and modify it in order to avoid duplicates.

How It Works?

The Plagiarism Checker analyzes text or uploaded documents against millions of online sources, detecting both exact matches and paraphrased content using AI technology.

It then displays results with percentages of unique and plagiarized content, highlighting duplicates and providing sources.

Key Features:

  • Free use is limited to 1,000 words, with expanded capabilities in premium plans.
  • Uses color coding to differentiate duplicate and unique phrases.
  • It supports multiple languages, including Spanish, Russian, Portuguese, Dutch, Indonesian, Italian, and Arabic.
  • Doesn't save uploaded material and trashes content after checking.
  • Multiple input methods include direct text pasting, file uploading (.tex, .txt, .doc, .docx, .odt, .pdf, .rtf), and webpage URL checking.
