Duplicate Content Checker
Find repeated passages in a draft or compare two versions before publishing. Review the exact text that matches, then copy or export a focused editing list.
Give each draft a clear purpose
Repeated wording can make an article or collection of pages harder to review. This checker finds matching sequences in the text you provide, so you can decide which passages to rewrite, combine or keep.
Use one-draft mode for repeated passages within a document. Choose two-draft mode to compare an existing page draft with a new version. Common phrases and deliberate quotations may match too; review the context before editing.
Locate matching sequences after their first appearance in one draft.
See which passages from your draft also appear in a comparison text.
Review actual matching text rather than relying on an unexplained originality score.
Filter the passage list, copy visible results or download a CSV report.
