What a similarity report shows
A Turnitin similarity report explains where overlap comes from. The percentage is useful, but the matched-source list and highlighted passages are what help you decide whether a match is harmless, properly quoted, missing a citation, or too close to source wording.
OriginCheckAI positions the report as a revision tool. You can review the evidence, fix citation gaps, shorten quotes, rebuild source-heavy paragraphs, and then decide whether the paper is ready for final submission.
- Similarity percentage for quick triage.
- Matched sources and highlighted text for evidence.
- Context for quotes, bibliography and common phrases.
- Downloadable PDF report for your own records.
How to read the percentage
There is no universal safe score. A reference-heavy paper can show a higher percentage while still being explainable. A short essay can show a lower score and still contain one risky copied paragraph.
Start with the largest and most specific matches. If the source relationship is clear and cited, the match may be acceptable. If the structure or wording follows a source too closely, revise the paragraph around your own claim instead of only changing a few words.
When to use this page instead of the main checker
Use the main Turnitin checker page if you want the broad service overview. Use this similarity report page when your main concern is source overlap, quote handling, bibliography matches, and how to interpret the PDF before submitting.
If AI writing risk is also important, pair the similarity report with the Turnitin AI checker page so both problems are reviewed before the deadline.
Questions students ask before checking
No. It reports text matches. You still need to review sources, citations, quotes and assignment context.
Start with the largest matched sources and any full-sentence or paragraph-level matches that are not clearly quoted or cited.
Yes. Reference lists can create legitimate matches, so the source context matters more than the percentage alone.
