Manuscript Similarity Detector

Automatic comparison of two scientific papers in PDF to quantify and characterize their overlap. It is not a plagiarism detector: it works at the level of content, concepts and argumentation.

The output includes a global similarity score (0–100), the list of shared topics and concepts, the references in common detected in both bibliographies, and a natural-language description of the differences and complementarities between the two works.

Useful for systematic reviews (screening methodological duplication between studies), literature surveillance, positioning a manuscript against a reference paper before submission, and supporting citation decisions when assessing whether two works cover equivalent ground.

How it works

  1. 1Upload the two papers as PDFs.
  2. 2The system compares content, concepts, argumentation and bibliographies.
  3. 3You get a 0 to 100 similarity score with shared topics, common references and key differences.

Who it is for

  • Authors positioning their manuscript against a reference work before submission.
  • Systematic review authors screening methodological duplication between studies.
  • Supervisors comparing drafts with closely related literature.
  • Researchers doing literature surveillance in their area.

Frequently asked questions

Is it a plagiarism detector?

No. It works at the level of content, concepts and argumentation, not literal text matching. It helps you understand how much two works overlap and where.

What does the result include?

The global 0 to 100 score, the list of shared topics and concepts, the references common to both bibliographies and a natural-language description of differences and complementarities.

When should I use it?

Before submitting a manuscript, to differentiate it from a close work; and in systematic reviews, to decide whether two studies cover the same ground.
