Skandy leverages advanced AI technology to deliver exceptional plagiarism detection. It uses a robust 9-stage contextual analysis system combined with the ultra-fast Siblius search engine, allowing it to ensure the detection of even the rarest and most hidden types of plagiarism — like unintentional self-plagiarism, paraphrasing, or misused quotes. The checker scans open sources for all duplicate sections and matches, which are highlighted in the detailed report. After you’ve edited any non-unique fragments, you can re-run the detection. Once it shows 100% uniqueness, you can be confident your text is free from plagiarism.
Skandy's OCR (Optical Character Recognition) technology enables it to analyze PDF files of any size, regardless of font, format, or layout — whether the text is in regular paragraphs, columns, or blocks. OCR accurately recognizes words, sentences, and paragraphs, ensuring that every element is thoroughly checked for matches and duplicate fragments. It even recognizes printed and handwritten texts, making it incredibly versatile.
The detailed report Skandy provides highlights all matches, duplicate sections, and questionable areas that need correction. If your text reaches 100% uniqueness, you can be sure there’s no plagiarism. If the percentage is lower, Skandy clearly identifies which specific text fragments, words, or sentences were borrowed, allowing you to make the necessary corrections to achieve complete uniqueness in your PDF document. Ensuring your work is plagiarism-free always enhances your reputation.

FAQ

Who may need to check PDF for plagiarism?

The Skandy AI Writing Checker is a smooth and accurate solution for writers
Plagiarism is often seen as both theft and fraud. When someone uses another person's words without citing the source and presents them as their own, it’s considered plagiarism. This can lead to serious consequences like fines, suspension from school or work, loss of trust, and damage to professional reputation. Whether intentional or unintentional, plagiarism can appear in any document, including PDFs.

The Portable Document Format category of files is widely used because they’re convenient for a range of professionals. Here’s why it’s crucial to ensure these files are plagiarism-free:

  • School, college and university students: the PDF format is often used for submitting essays and assignments. Ensuring your work is 100% original is key to getting good grades and maintaining academic integrity.
  • Teachers and researchers: Checking PDFs for plagiarism detection is vital to confirm that academic papers meet ethical standards and don’t contain unauthorized borrowings.
  • Webmasters and marketers: PDFs are commonly distributed in newsletters and offered as guides to clients or website visitors. If a client spots plagiarism, it can damage the trust in your brand and website.
  • Copywriters and editors: Copywriters often create and format content in PDFs, while editors oversee its distribution. Unique content is essential for attracting clients and readers, and it helps avoid legal risks.
  • Journalists and writers: Professionals in writing often use PDFs to present their work, complete with text, graphics, and illustrations. Ensuring text originality demonstrates professionalism and builds trust.
  • Entrepreneurs: Business owners use PDFs for various documents, articles, letters, and marketing materials. Original text content helps differentiate your business from competitors and attract more customers. PDFs maintain consistent formatting across devices, making them ideal for a wide range of documents.
PDFs preserve your text layout exactly as intended, no matter which device the document is opened on. The formatting remains consistent, with text blocks staying in place, so there’s no risk of the layout shifting across different devices. This makes PDFs a popular choice for research papers, student assignments, corporate documents, and content projects. Ultimately, ensuring the uniqueness of PDFs is crucial for anyone who relies on this format.
