One review workspace
Features that keep evidence close.

PlagCheckr features
Plagiarism analysis
Inspect similarity matches against web pages and academic sources, with the source evidence connected to highlighted passages.
Source-aware review
Keep claims, citations, and source context close while you revise a document, so attribution decisions rest on visible evidence.
Report highlights
Generate passage-level highlights after your initial report to pinpoint exactly which parts need rewriting or citation.
Downloadable reports
Share a clear record of findings with supervisors, editors, or co-authors — the people responsible for the final review.
Private by default
Documents are retained for up to 30 days, then automatically deleted — and removable manually at any time. Nothing is added to a public database.
