Why VERITAS
A plagiarism checker that gives you more than a similarity percentage
A useful plagiarism report should show more than a percentage. VERITAS combines plagiarism detection with source identification and contextual similarity analysis, helping you review matching passages, quotations, translated matches, and original text more accurately.
Accurate Quotation Detection
VERITAS identifies quotations and properly attributed passages separately from other text matches, improving the accuracy of the similarity report.
Translated plagiarism detection
VERITAS can detect cross-language and translated text matches, helping uncover source similarities that simple exact-match checkers may miss.
Automatic source classification
The system classifies different types of sources, including academic publications, standards, official documents, and other online material, for more informative plagiarism detection and similarity checking.
Detailed plagiarism report
Receive a clear PDF similarity report with match percentages, identified sources, explanations, and color-coded text.
Report delivered by email
Your plagiarism check continues securely on the server, and the completed similarity report is sent automatically by email.
Academic plagiarism checker
Check Theses, Dissertations, Essays, and Research Papers for Plagiarism
Before submitting academic work, a plagiarism check can reveal matching passages that may need a citation, clearer attribution, or revision. VERITAS works as an online plagiarism detector and similarity checker for theses, dissertations, essays, research papers, and other academic documents in DOC or DOCX format.
A similarity score is not, by itself, proof of plagiarism. Matches may include quotations, common wording, references, or properly attributed material. VERITAS therefore shows matched passages and identified sources in a detailed similarity report, allowing each result to be reviewed in context.
