FAQ

Questions and answers

Plag is a leading online platform dedicated to detecting and preventing plagiarism, ensuring the authenticity and originality of written content. Powered by advanced algorithms and extensive databases, our platform scans texts for similarities to internet sources and published materials. We offer a comprehensive set of features, including plagiarism removal and grammar checking, designed to enhance the quality and precision of your writing. Widely trusted by students, teachers, writers, and businesses, our service safeguards against potential legal complications associated with plagiarism, making it an indispensable tool for maintaining integrity in your work.
Our process begins by extracting the text from your file, which is then meticulously compared using our advanced text-matching algorithms. These algorithms conduct thorough scans across diverse databases containing both public and paid access documents. As a result, any text similarities found between your document and the source documents are highlighted for your convenience. Additionally, we calculate the percentage of similar text, known as the similarity score, along with other relevant scores. Finally, an insightful originality report is generated, providing a comprehensive overview of the similarity matches found in your document and the corresponding source documents, accompanied by the associated scores.
Upon uploading your document, it undergoes a comprehensive comparison with our extensive database of publicly accessible documents and scholarly articles. Throughout this process, our text-matching algorithms diligently identify similarities between the words in your document and those present in other texts. The algorithm calculates the percentage of similarity by tallying all the matches, which is referred to as the similarity score. The text matching algorithms not only identify exact matches but also account for matches that may be fragmented across the text. To assess the risk of plagiarism, we focus on the presence of larger continuous blocks of similar text in your document. Even a single significant block of similar text can indicate potential plagiarism. Hence, it is crucial to note that documents with a relatively low percentage of similarity can still be deemed as high risk based on the presence of substantial textual matches.
The detailed report provides two essential features that facilitate a comprehensive analysis of your document. Firstly, it highlights the similarities and matches in different colors, allowing for easy identification and differentiation. This visual representation aids in understanding the extent and nature of the matched text within your document. Secondly, the report grants you the ability to inspect and directly access the original sources of the matched text. This valuable feature enables you to delve deeper into the sources and verify the context and accuracy of the matched content. By effortlessly accessing the original sources, you gain a deeper understanding of the textual connections and can make informed decisions regarding appropriate attribution or necessary revisions.
By utilizing the free check option, you will receive a comprehensive text similarity range, ranging from 0-9%, 10-20%, or 21-100%. This provides you with valuable insights into the level of similarity detected in your document. Additionally, you have the opportunity to easily share the generated similarity report with your educator, facilitating transparent communication and fostering academic integrity. Furthermore, our service offers a real-time plagiarism check, ensuring that you can promptly assess the originality of your content. With this feature, you can proactively identify and address any potential plagiarism concerns, enabling you to make necessary revisions or properly attribute external sources.
We place the highest emphasis on safeguarding the privacy of your personal data and documents. Our commitment revolves around the principle that what belongs to you remains exclusively yours. We strictly prohibit the use of any uploaded documents for copying or distributing purposes in any form. Moreover, your documents are not included in any comparative databases. Your data, along with the contents of your documents, is fully protected by legal measures. Access to this information is limited to you and our authorized employees, solely for the purpose of providing customer support. We adhere to stringent confidentiality guidelines to ensure that your data remains secure and confidential at all times. Your trust in our service is of utmost importance to us, and we take all necessary steps to maintain the privacy and integrity of your personal information.
