What NoPlagio is
NoPlagio checks two things at once: textual overlap with web and academic sources, and signals of AI-generated content. It supports a very large number of languages and several document formats, and produces highlighted reports with links to the matched sources.
What you can do with it
- Screen theses, reports and manuscripts
- Compare multilingual submissions
- Open the sources behind matched passages
- Identify paragraphs needing revision
- Prepare reports for supervisors
Who it is for
- Students and researchers
- Teachers and academic institutions
- Editors handling multilingual material
What to watch out for
- Similarity percentages include properly quoted and cited material, common phrases and reference lists; read the report rather than trusting a number
- AI detection within the report has the usual reliability limits
- Uploaded work is sent to a third party, so unpublished or confidential documents need care
- Institutional use needs a clear policy on retention and who can see reports
