Similarity with context
A match is not automatically plagiarism.
Quotations, common language and correctly cited passages can all create overlap. Proofademic separates source matches by risk so reviewers can inspect what matched, where it came from and how it is used.
Original analysis begins with a clear claim, supporting context and a documented method.
This passage follows the source unusually closely and should be reviewed against the original wording.
As prior research has established, the surrounding citation may explain the overlap.
Source transparency
Move from a percentage to the passages behind it.
A single similarity score cannot explain why text matched. Open the source trail, compare the wording and keep citation context attached to the review.
- 01Matched passageSee the wording that triggered the result.
- 02Original sourceTrace the match back to its surfaced source.
- 03Risk classificationPrioritize close wording without hiding lower-risk overlap.
Institutional policy is most effective when detection evidence is considered alongside a student’s drafting history.
Review workflow
Check, revise and share without losing the trail.

Institutions + teams
Keep source evidence attached to every handoff.
Move a report between instructors, integrity teams, editors and reviewers without reducing the result to a percentage.

Common questions
Before you check a document.
No. Similarity can come from quotations, citations, common phrases or uncited copying. Proofademic surfaces the matched text, source and risk level so a person can review the context.
There is no universal acceptable percentage. A similarity score shows how much text matched the sources checked, not whether plagiarism occurred. Review the matched passages, citations and assignment policy before deciding what the score means.
Yes. Quotations, references, assignment wording and other correctly cited material can still resemble source text. Check each match and its citation context instead of trying to reach a particular percentage.
No. A 0% score means the checker did not find matching text in the sources it reviewed. It cannot prove that every idea is original or that every source was cited correctly.
A checker may surface close paraphrases when wording or structure overlaps a source, but no checker can identify every paraphrased idea. Writers still need to cite borrowed ideas even when the wording has changed.
The report includes an overall match percentage, unique-content score, high- and low-risk matches, surfaced sources, matched-word counts and sentence-level details.
Yes. You can download a print-ready PDF report or enable a share link so another reviewer can view the results.
Plagiarism checking and AI detection answer different questions. Proofademic provides both workflows so source overlap and AI-writing signals can be reviewed separately.
