Plagiarism Checker

Plagiarism Checker UOM is a text similarity tool for students, researchers, editors, and content teams that need to verify originality. It compares two texts or a text against a set of sources to quantify overlap and identify potentially copied material. The tool returns a global similarity score, a per-source breakdown, and a list of matched passages with exact offsets to support citation and revision decisions.
Conceptually, the analysis combines token-based and structural indicators. It normalizes whitespace, tokenizes into n-grams, and uses TF-IDF cosine similarity to gauge direct and broader similarity. Paraphrase signals are flagged through sequence-alignment heuristics to catch rewritten passages. When multiple sources are provided, per-source similarity is reported alongside the overall score.
Who benefits? Students preparing papers, researchers drafting manuscripts, editors conducting checks, and content teams maintaining publication standards. The tool supports multilingual inputs and can operate on short passages or full documents, designed for high-throughput workflows with clear export options. Core features include dual-input comparison, per-source match lists, overall score, passage offsets, and exportable reports (CSV/JSON). Use cases include assignment checks, manuscript originality reviews, and web content audits.
