4-Gram Jaccard Shingle Overlap & Exact-Phrase Verification
First, Mode 1 converts your draft and source into 4-word shingle sets A and B. Next, it computes Jaccard overlap |A ∩ B| ÷ |A ∪ B| × 100 and draft containment |A ∩ B| ÷ |A| × 100. Meanwhile, Mode 2 builds quoted exact-phrase search links for live web and Google Scholar verification.
Because our Plagiarism Checker applies these rules automatically, you avoid manual rounding mistakes. Furthermore, users looking for similarity checker or content theft checker workflows can test multiple scenarios side by side before finalizing their work.
