Seeing exactly which passages overlap is more useful than a bare similarity number.
Plagiarism Detector lets you toggle highlighting and produces a copyable, report-style summary of the matches.
How to use Plagiarism Detector
- Paste your text and the source you want to compare against.
- Keep highlighting on to mark matched passages in place.
- Copy or download the report-style summary of the result.
Use cases
- Marking overlapping passages directly in the text.
- Producing a short shareable similarity report.
- Reviewing a short passage against a known source.
Good to know
Plagiarism Detector highlights the passages your text shares with a pasted source and summarizes the percentage and matched-word counts in a report you can copy or download. Highlighting can be turned off for a score-only view. It compares only against the source you paste, with no web access, and very short input is matched with shorter phrases and noted. Long input is compared up to the first 60,000 characters per box.
Frequently asked questions
What do the highlights represent?
Each highlight marks a passage in your text that matches a word sequence in the pasted source, so you can see exactly where the overlap is.
Can I get a result without highlighting?
Yes. Turn highlighting off for a score-only view; the copyable report still lists the percentage and matched-word counts.
Does it compare against anything other than my source?
No. It only compares your text against the source you paste; there is no web or database lookup.
Why does a short passage still show a match?
For short input it automatically uses shorter phrases so it can still compare, and it notes when it does this.
