PlagiarismCheck

PlagiarismCheck is an online tool designed to detect plagiarism and AI-generated content in written texts. It serves educators, students, writers, and content creators by analyzing documents for originality and authorship. The platform uses advanced algorithms to compare submitted text against a vast database of academic papers, web pages, and other sources, providing a detailed similarity report with a percentage score. Users can upload files or paste text directly, and the system scans for both direct copying and paraphrased plagiarism. One of the core functions is AI detection: the tool identifies text that may have been generated by large language models like GPT, helping teachers maintain academic integrity and helping writers ensure their work is original. The results are presented in an interactive interface that highlights matched sections, shows source links, and gives a breakdown of similarity by category (e.g., internet sources, publications, student papers). Users can view a side-by-side comparison of the original and potentially plagiarized passages. For educational institutions, PlagiarismCheck integrates with learning management systems (LMS) such as Canvas, Moodle, and Blackboard, allowing instructors to automatically check student submissions within their existing workflow. It also supports batch uploads and provides downloadable reports in PDF or Excel format. For businesses, the tool helps verify the originality of marketing copy, internal documents, and employee-generated content, reducing the risk of copyright infringement. The platform prioritizes confidentiality: uploaded texts are stored securely and are not shared with third parties. It also includes a writing improvement feature that suggests rephrasing for flagged passages, helping users learn
