Understanding Similarity Scores
What different percentages typically mean
Low Similarity
Generally acceptable. Minor matches are usually common phrases or properly cited content.
Moderate Similarity
Review recommended. May be fine if matches are cited quotes, but verify all sources are properly referenced.
High Similarity
Needs attention. Review all matches carefully—add citations, paraphrase more, or reduce quoted content.
Note: Acceptable thresholds vary by assignment and institution. Literature reviews may naturally have higher similarity than original research.
Why Check Similarity Before Submission
Verify Your Citations
Make sure all quoted material is properly cited. Catch missing citations before your professor does.
Identify Accidental Matches
Sometimes you match sources you've never seen. Find and paraphrase these sections before submission.
Avoid Plagiarism Charges
Plagiarism accusations can result in failing grades or expulsion. A $3.99 check is cheap insurance.
Submit with Confidence
Know your exact similarity score before submission. No surprises, no anxiety.
Your Paper Stays Private
Unlike official institutional submissions, checking your paper with Reilaa does NOT add it to any database. Your paper is processed for analysis and immediately deleted. No storage, no sharing, no self-plagiarism concerns for future submissions.
