Plagiarism Checker: Compare Two Texts for Similarity
Measure word-level overlap between a source text and a comparison text with a similarity percentage.
UtilityTools Team
Our Plagiarism Checker compares two blocks of text and reports what percentage of words overlap. It is a straightforward duplicate-detection helper for students and editors.
Paste the original source in the first field and the suspect text in the second. The tool tokenizes words and calculates matched versus total counts.
High similarity does not always mean plagiarism — quoted material and common phrases will register matches. Use the score as a signal, not a verdict.
For thorough academic review, combine this with proper citation practices and human judgment.
