Accurate, In-Depth & Shareable Plagiarism Reports

Our goal is a report that makes matching text understandable. These reporting capabilities are planned and will depend on the connected matching service.

Sentence highlighting

See the passages that need attention, with surrounding text kept intact.

Matched sources & similarity percentages

Follow source URLs and review the amount of overlap. A similarity percentage is not by itself proof of plagiarism.

Shareable reports & PDF export

Planned sharing and downloads will help keep findings, source details, and discussion together.

GramProof source review

Highlighted passage → source context

Source URLs and match percentages will appear only after a real scan.

Look beyond identical wording

Detect Patchwork & Paraphrased Plagiarism

A passage can borrow from several sources, or replace words while keeping another author’s ideas and structure. Reviewing these cases requires more than a search for an exact sentence.

GramProof’s planned similarity workflow will help surface partially rewritten and combined passages where provider support allows. Paraphrase detection is not available in this preview.

Several sources. One draft. A closer review.

Compare the wording, structure, and citations together. Proper attribution matters even when the words have changed.

Hybrid Plagiarism Checks

A planned combination of source coverage and responsible handling. The sources actually checked will be disclosed when a provider is connected.

Web sources

Compare passages with covered web material and follow matches to their original context.

Academic / journal sources

Academic coverage will depend on provider access and licensing. We do not claim access to every journal or private database.

Privacy & security

This preview converts uploads locally and does not send or store documents for plagiarism analysis. Live-service handling will be explained before launch.
